About Science Frontiers

Science Frontiers is the bimonthly newsletter providing digests of reports that describe scientific anomalies; that is, those observations and facts that challenge prevailing scientific paradigms. Over 2000 Science Frontiers digests have been published since 1976.

These 2,000+ digests represent only the tip of the proverbial iceberg. The Sourcebook Project, which publishes Science Frontiers, also publishes the Catalog of Anomalies, which delves far more deeply into anomalistics and now extends to sixteen volumes, and covers dozens of disciplines.

Over 14,000 volumes of science journals, including all issues of Nature and Science have been examined for reports on anomalies. In this context, the newsletter Science Frontiers is the appetizer and the Catalog of Anomalies is the main course.

From a dayglow experiment aboard NASA's satellite DE-1 (Dynamic Explorer-1 ) comes an unexpected discovery of considerable potential importance. Looking down on the earth, the DE-1 records the light emitted by atmospheric oxygen at altitudes of about 200-300 kilometers -- this is the so-called "dayglow." The experimenters, L. Frank, J. Sigwarth, and J. Craven, all at the University of Iowa in Iowa City, have found that their dayglow images are speckled with transitory dark spots. "According to Sigwarth, each hole expands like a drop of dye spreading out in a glass of water; within about 30 seconds the dayglow intensity drops by about 95 percent over an area of about 3,000 square kilometers. Then, over the next 3.5 minutes, the dayglow intensity increases toward its normal value as the hole grows to an area of about 25,000 km2 ." The Iowa group thinks that the holes or spots are created by meteors hitting the upper atmosphere because the spots follow the same time distribution as meteors. For example, they are more frequent during the well-known meteor showers. The theory is that the dark spots are formed when ice associated with the meteors is turned into water vapor, which reacts with the atmospheric oxygen producing the dayglow, in effect removing temporarily part of the light ...

Science Frontiers ONLINE No. 95: Sep-Oct 1994 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Gamma-ray flashes in the upper atmosphere Something strange is definitely going on in the upper atmosphere, particularly above thunderstorms. We have already reported on the mysterious light flashes (SF90) and radio emissions (SF#94). Now, we record similar, possibly intimately related flashes of energy in a different portion of the electromagnetic spectrum. "Detectors aboard the Compton Gamma Ray Observatory have observed an unexplained terrestrial phenomenon: brief, intense flashes of gamma rays. These flashes must originate in the atmosphere at altitudes above at least 30 kilometers in order to escape atmospheric absorption and reach the detectors." The energies of the gamma rays in the flashes are very high. They are typical of the braking radiation (Bremsstrahlung) from 1,000,000 electron-volt electrons. Since most of the gamma flashes originate over regions where thunderstorms are frequent, it is tempting to associate them with lightning. Ordinary lightning, however, is not energetic enough to generate the gamma flashes and, of course, it does not occur above 30 kilometers altitude anyway. G.J . Fishman et al, who reported on this new phenomenon in Science, speculate that some hitherto unrecognized, high altitude electrical discharges occur high above areas hosting thunderstorms. Possibly, upwardly directed lightning (" rocket lightning") is involved in all three of the newly found flashes in the radio, optical, and gamma portions of the electromagnetic spectrum. (Fishman ...

Science Frontiers ONLINE No. 35: Sep-Oct 1984 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Infrared Atmospheric Waves When the night sky is photographed in the infrared portion of the spectrum, luminous wave-like structures appear in the upper atmosphere. The wave crests are about 50 kilometers apart; lengthwise, they stretch up to 1.000 kilometers; altitude, about 85 kilometers. As many as ten waves may be seen at the same time. Morphologically, these waves resemble noctilucent clouds, which are sun-illumined, high-altitude clouds. The infrared waves, however, appear when the sun is well below the horizon. Since these waves are seen only at low angles over the horizon, some geophysicists propose they are the result of a geometric effect produced by viewing a rippled layer of weakly emitting gases in the upper atmosphere. When one looks at this rippled layer just above the horizon, one sees alternating thick and thin sections due to the perspective. The thick portions will appear brighter than the thin sections. As for the origin of this postulated rippled layer; no one is sure. Gravity waves may be involved. (Herse, M.; "Waves in the OH Emissive Layer," Science, 225:172, 1984.) Comment. As described in our Catalog Lightning, Auroras, Nocturnal Lights. luminous atmospheric waves are, on rare occasions, visible to the naked eye.

"In August 1984 I had just left work at 5.30 p.m . and was walking along an unfrequented side street as a short cut to get to my bus. The weather was cloudy and sultry, but there had been no reports of thunder in the area that day. I came to a junction in the pavement which led only to car-parking for buildings lying farther back when a bubble about the size of a tennis ball sailed out of this side-way, in a straight line, about the level with my shoulders, at a distance of some five or six feet. I stared at it in amazement, for where could a bubble have come from at such a place and time?" "I was further amazed that it did not disintegrate...While gazing at the bubble it seemed to me that there was a dark band round it, which I interpreted as being a reflection of the tarmac road, although subsequently when experimenting with childrens' bubble mixture I discovered that bubbles never reflect anything so discernible." "The bubble proceeded at its original speed, curving around ...

Noel is an astronomer at the National Astronomical Observatory located on the outskirts of Santiago. He is a veteran of hundreds of nights worth of stellar observations over almost 30 years. In the latest number of the Journal of Sci entific Exploration, he reported some of his more perplexing sightings in the Chilean skies, two of which are related below: "At approximately 22:30 local time on January 17, 1980, I was in front of my home in the eastern suburbs of Santiago de Chile. The sky was cloudless, although there was some smog, especially in the west in the direction of downtown. Sunset had occurred at 20:55 local time. "At that time I observed a point-shaped luminous object at an elevation of about 20 degrees; it was moving at a rather slow angular velocity from southwest to west approximately. No noise was heard and it looked like an artificial satellite, except for the direction of its motion. Its brightness, color and angular velocity reminded me of the old Echo artificial satellite from the 1960s. The object disappeared from sight during the few seconds it took me to call two persons to participate in the observation. It was not apparent how the object had disappeared from view since there were no sources of obscuration evident. Having become puzzled by this observation I continued watching that same region of sky from time to time. "About ...

... Science Frontiers ONLINE No. 74: Mar-Apr 1991 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Gaia on mars?H.L . Helfer, University of Rochester, noting the absence of extensive cratering on the northern plains of Mars, suggests that some 2-3 .5 billion years ago these plains were covered with oceans. These ancient seas, perhaps as much as 700 meters deep, protected the plains from direct impacts. Further, crater density counts for Chryse and the Martian highlands imply that Mars possessed a fairly dense atmosphere until about 1.5 billion years ago. In his Abstract Helfer speculates as follows: "With both early Earth and early Mars having similar atmospheric compositions and not too dissimilar atmospheric structures, it is reasonable to suppose that the warm Martian oceans, like the ancient oceans of Earth, would develop anerobic and aerobic photosynthesizing prokaryotes and structures like stromatolites. Their development might have changed the Martian atmosphere. Their fossils might be found along the fringes of the old oceans, the northern lowland plains." (Helfer, H.L .; "Of Martian Atmospheres, Oceans, and Fossils," Icarus, 87:228, 1990.) Comment. The Gaia influence is seen in the molding of the Martian atmosphere into something more conducive to the development of life. One can also speculate that, if life did develop on Mars, it could have seeded the earth via bits of debris blasted off by meteorite impacts. Several meteorites picked up in Antarctica are thought to have come from Mars ...

During the 10-minute flight, more than 500 lightning-related events were recorded over that part of the globe visible from the rocket's altitude. "Among these is a class of about 23 events all having an anomalous signature, with obvious clustering of optical impulses or continuous emissions, and resulting durations of several hundred milliseconds. Such durations are much longer than typical for lightning-related events recorded at the rocket, which are more frequent overall. Every anomalous optical event (AOE) was accompanied by broadband VLF signals of a distinctive character...In considering possible sources above 30 km we find that the AOEs do not seem to resemble other natural optical phenomena, such as meteors which burn up well above 30 km in the mid-latitude atmosphere."

The smaller ones are completely consumed. A few bigger ones reach earth and are renamed "meteorites." So far, all of this is well-understood. But when meteors begin to burn up much above 100 kilometers, a problem arises. The air there is normally much too thin to cause incandescence and burn-up. Observational anomalies are abundant. Two Leonid fireballs were seen glowing at 160 kilometers by Japanese scientists. In 1998, a Dutch team in China detected bright Leonids at 200 kilometers! In addition, some Russian reentering space-craft began glowing well above 100 kilometers. ANAL is a solid phenomenon. Of course, the density of the upper atmosphere does increase somewhat when solar activity is high. Atmospheric gravity waves can also cause the atmosphere to bulge out. But these effects are inadequate to explain all observations. R. Spalding, at Sandia National Laboratories, ventures that ions in the upper atmosphere are electrostatically attracted to meteors and create light when they collide with them. A. Ol'khovatov suggests that "plasma instabilities" may be involved.

A preliminary analysis by Michael Mumma, of Goddard Space Flight Center in Maryland, and his colleagues. indicated that processes analogous to optical pumping in laboratory lasers were taking place and led to the coining of the term 'natural lasers.' Now, Deming and colleagues from the Goddard team have taken new observations of emission from Mars and Venus at wavelengths near 10 micrometers. and modelled them to show that stimulated emission -- the effect which makes lasers so powerful -- accounts for up to seven per cent of the total emission. This is not a large amplification factor by laboratory standards, particularly for a CO2 laser. But, the authors speculate that the sheer size of the natural lasers could make them useful tools in the future for communicating with distant civilizations beyond our own planetary system." The atmospheres of Mars and Venus are almost pure CO2 . The CO2 molecules are excited by the absorption of energetic solar photons; then, thermally emitted photons at about 10 micrometers from lower reaches of the atmosphere collide with the excited molecules, stimulating them to emit another 10-micrometer photon, thus doubling the number of photons. This is typical laser action. ...

Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Did a methane burp down twa800?The potential for methane eruptions from offshore sediments to sink ships and down aircraft was proposed by W.D . McIver way back in 1982, in the Bulletin of the American Association of Petroleum Geologists. (SF#25/208) The source of methane-gas releases (" burps") is the rapid decomposition of methane hydrate, which exists in prodigious quantities in offshore sediments. Some geologists have estimated that there is twice as much methane in methane-hydrate deposits as in all terrestrial natural-gas fields. What makes methane hydrate potentially lethal is its instability. Landslides and small quakes can release huge plumes of methane bubbles into the ocean and thence into the atmosphere. Ships might founder in the lowdensity froth of bubbles, and aircraft might be adversely affected, too. This is where TWA800 comes in. R. Spalding, a scientist at Sandia National Laboratories has been monitoring mysterious atmospheric explosions and believes that some of these detonations are consistent with the atmospheric ignition of huge methane plumes. (Other detonations are due to meteors.) Spalding proposes the following scenario: The ocean floor releases a massive methane gas plume, which rapidly rises to the surface and ascends into the atmosphere. The lighter-than-air methane cloud gains altitude, mixing with oxygen and thereby gaining explosive poten tial. An electrical disturbance -- possibly caused by the rising cloud itself or a lightning strike -- detonates the cloud. Awesome energy is instantly re leased in the ...

P. Huyghe, coauthor with L. Frank of The Big Splash, responded to SF#125 with three recent articles. Two reply to major criticisms of the icy-comet theory; the third gives geological and geophysical reasons why there must have been icy comets or some other substantial influx of water and carbon to the earth's surface down the geological eons. No instrumental artifacts. The basis for the 1985 claim of L. Frank et al that small, icy comets continually bombard the earth's upper atmosphere came from photos taken far above the earth from the Dynamics Explorer 1. Large, transient "holes" appeared in the atmosphere. These were attributed to vapor clouds created by small, icy comets. (SF#44) Critics claimed that these "holes" were no more than instrumental errors. L.A . Frank and J.B . Sigwarth have investigated this possibility and have rejected it.

Our climate, atmospheric oxygen level, ocean composition, and similar vital conditions are kept livable by life's waste products, such as the oxygen emissions of plants. That something like Gaia is required is seen in the extreme disequilibrium of the earth's atmosphere compared to the near-equilibrium of the atmospheres of apparently lifeless Venus and Mars. For example, our atmosphere's 21% oxygen, a highly reactive gas, is many orders of magnitude higher than one would expect on a lifeless planet. Furthermore, life-friendly conditions have been maintained for billions of years despite large changes in the sun's output and the traumas of asteroid impacts. T.M . Lenton, writing in Nature, asks a salient question: How has planetary self-regulation (Gaia) been established and maintained by evolution and natural selection which operate on the level of individuals? In other words, evolution tells us that organisms should evolve so as to leave the most progeny not so as to regulate the atmosphere. Lenton answers that there must be feedback loops from the planetary environment that steer the evolution of individuals in the "proper" direction. Lenton goes on to explore some of these many feedback mechanisms; one obscure loop involves the production of dimethyl sulfide by marine phytoplankton. Truly, it ...

Named after the valley, the lights have been named: The Hessdalen Phenomenon. A research station was set up in the valley in 1983. During January-February 1984, eight different kinds of instruments were in use, with the following results: Camera with grating : Three pictures showed a continuous spectrum. No spectral lines were seen on any picture. IR-viewer: This instrument was used too little to drawn any conclu sion. Spectrum-analyzer: Sometimes there were electromagnetic signals with harmonics of about 80 MHz. Seismograph : No local seismographic activity was measured. Magnetograph : The magnetic field did sometimes change when the lights showed up. There also seemed to be a correlation with the mag netic pulsation. Radar : The lights could be seen on radar. The speed varied all the way from 0 to 30,000 km/hour. Sometimes the radar saw something moving at a low speed, but no lights were seen by eye. Clearly, there was something there, but only the radar showed it. Laser : A laser-beam was directed toward the light, and the behavior of the light changed.

Godfrey (National Optical Astronomy Observatories) has discovered an unusual feature in the planet's atmosphere. His mosaics reveal a hexagon centered on the north pole. Since neither probe flew directly over the pole, the complete scene has to be created by 'stretching' a series of photographs taken from the side as Saturn rotated, then fitting them into a polar projection." The straight sides of the hexagon are each about 13,800 kilometers long. The entire structure rotates with a period of 10h 39m 24s, the same period as that of the planet's radio emissions, which is assumed to be equal to the period of rotation of Saturn's interior. The hexagonal feature does not shift in longitude like the other clouds in the visible atmosphere. The pattern's origin is a matter of much speculation. Most astronomers seem to favor some sort of standing-wave pattern in the atmosphere; but the hexagon might be a novel sort of aurora. More extreme speculation has Saturn's radio emissions emanating from the hexagon (something we can see and which has the right rotation period) rather than from the planet's interior (something we cannot see).

(SF#110) The media have said little about the staggering quantities of methane and higher hydrocarbons locked up in frozen hydrates around the edges of the continents. Actually, the small methane burps are minor problems compared to the catastrophic climate changes that could be forced if just a small portion of the gases frozen under the sea floor were released into the atmosphere. Gas-hydrates are unimpressive when brought to the surface -- just dirty, fizzy ice. However, taken together, they contain more carbon than all the world's oil fields, perhaps much more. Most estimates fall between 1,700 and 11,000 billion tons, but there is one scientist who pegs these cold-storage carbon deposits at 4,100,000 billion tons. In comparison, human releases of carbon to the atmosphere via the burning of wood, gas, coal, and even the collective flatulence of all the planet's animals are trivial. Geological evidence confirms that past climate swings were associated with large injections of carbon into the atmosphere and oceans. A major contributor to these "carbon burps" may be decomposing methane hydrate. Until recently, climatologists have questioned the sizes of gas-hydrate deposits, but cores extracted from the Blake Ridge off the Carolina coast confirm ...

Both classes of phenomena are written off as either observer misperceptions or idiosyncracies of the earth's atmosphere. Of course, such treatment of strange phenomena is not new, nor is it undesirable, for we do want to confront reality whatever it might be. However, the two "wipes" in Sky & Telescope do seem a bit arrogant, especially when famous scientists do not hesitate to employ ghostly ephemera to support theories favored by the establishment. Strange eclipses. Down the years, many fantastic solar coronas have been sketched during the few minutes of totality. Long coronal petals and errant streamers, often asymmetrically arrayed, are common in the Nineteenth Century astronony journals. Scientists have no problems with these. It is the highly geometrical coronas that are hard-to-account-for. The reported colored coronas, too, seem unlikely. Red, blue, and green hues are definitely frowned upon. Coronas should be brilliant white, perhaps yellowish. S.J .

What about us -- Terra, the third planet? A February article in Sky and Telescope begins: "Military satellites have been watching huge meteoroids slam into the Earth's atmosphere for nearly two decades." Secret until recently, infrared scanner data from military satellites have detected 136 atmospheric explosions since 1975 with yields of 1 kiloton or more. There may actually have been as many as four times this number, because the satellites are programmed to look for unnatural events, such as nuclear detonations. They often ignore extraterrestrial projectiles. Why aren't earthbound observers aware of all these atmospheric explosions? Because most are infrared events; few emit enough visible light to attract the attention of ground-based observers. However, two of these "secret" meteoric events might explain some Fortean phenomena recorded over the last two centuries. April 15, 1978. Over Indonesia. A military satellite watched a colossal daylight fireball that, for one second only, would have rivaled the sun to anyone watching from the ground below and alert to such phenomena.

But Martian models that assume water to have been the eroding agent encounter difficulties, because Martian gravity is too weak to hold the hydrogen when water is dissociated by solar radiation. A better bet, say Y.L . Yung and J.P . Pinto, is liquid hydrocarbons; i.e ., petrol. Starting with a methane atmosphere, at 0.1 earth's atmospheric pressure, the natural loss of hydrogen would lead to the polymerization of hydrocarbons and eventual condensation. "Petrofalls" from this atmosphere could cover the Martian surface to a depth of one meter and lead to heavy erosion. (Anonymous; "Martian Surface in Good Spirits," New Scientist, 79:19, 1978.)

We humans know to our dismay that we have the capacity to modify the earth's environment, but could we perhaps exercise better judgment and terraform Mars? C.P . McKay et al have looked into this possibility: "From our analysis, one could propose the following sequence of events: production of CFCs (or other greenhouse gases) starts on Mars and the surface temperature warms up by about 20 K. The regolith and polar caps release their CO2 and the pressure rises to 100 mbar. One of two things could then happen. If there were large regolith and polar CO2 reservoirs, the pressure would continue to rise on its own. If these were absent, the CO2 pressure would stabilize, and additional CO2 would have to be released from carbonate minerals. At this point (perhaps between 100 and 105 years) Mars may be suitable for plants. If there was a mechanism for sequestering the reduced carbon, these plants could slowly transform the CO2 to produce an O2-rich atmosphere in perhaps 100,000 years. If sufficient N2 could also be released from putative soil deposits, and the CO2 level kept low enough, then a human- breathable atmosphere could be produced. (McKay, ...

This portion is densely cratered from a period pf heavy meteorite bombardment. It is also carved by many channels that are thought to have been cut in ancient times by flowing water, water which quickly escaped into space or combined chemically with Martian minerals. The present atmosphere of Mars, in consequence, contains little water vapor. But some of the Martian landscape, notably Alba Patera, raises questions about the above scenario. The anomalous characteristic of Alba Patera is its relative smoothness and scarcity of impact craters. This Martian real estate is believed to be 2 billion years younger than the rest of the planet. Even so, it, too, is marked by "fluvial" features that resemble stream beds. Question #1 . How did Alba Patera get smoothed out or "reworked"? In other words, what happened to the ancient craters that must have pocked its surface, as they do everywhere else? Question #2 . Where did the water come from to cut Alba Patera's stream beds if all of the Martian water disappeared 2 billion years earlier? One line of thought maintains that "fluvial" does not mean "pluvial," and that Martian water has come from below rather than as rain from the atmosphere.

This synchronism suggests some sort of energy interchange between Io and the top of Jupiter's atmosphere. The theory now in vogue states that Jupiter's rotating magnetic field induces a voltage across 2300-mile-diameter Io, resulting in an electrical current of some 5 million amperes flowing between Io and Jupiter, some 262,000 miles away. In this bizarre electrical circuit, the two moving "terminals" on Jupiter, in the northern and southern hemispheres, are heated by the current flow and show up as fuzzy infrared-bright spots.

The satellite, called Lageos, is covered with laser reflectors so that it can be tracked with high precision. At its altitude of 3700 miles, the earth's atmosphere is supposed to be so thin that friction will bring the satellite only 1/250th of an inch closer to the earth each day. The trouble is that Lageos actually falls at ten times this rate. In 1979 it descended 60% faster than it does now. Lageos will stay in orbit several hundred thou-sand years, but space scientists are understandably concerned about their theories about the upper atmosphere. Many suggestions have been made to explain this anomaly. Some say the atmosphere is thicker than expected; others prefer to think there is more helium than predicted; but the "plasma drag" effect seems to fit the situation the best. Lageos may, in fact, be electrically charged and interacting with the surrounding cloud of electrically charged particles and is ever so slightly braked by the electrical forces.

Huyghe has recently written more about Frank's discovery, his theory, and its reception by the scientific community. "These comets are not occasional visitors, he [Frank] says, like the one that comes by every 76 years and -- lucky for us -- never actually drops in. No, these are very small, cometlike objects that enter our atmosphere at a rate of 20 per minute, he says. These comets, which he believes must contain about 100 tons of water apiece, vaporize on impact with the atmosphere and fall as rain or snow. Now that may seem like one sizeable cold shower, but on a yearly basis he says it's actually only a tiny fraction of the annual preciptation. Then again, over a span of 4.5 billion years, which is about how old the earth is, that's enough water, he says -- trumpets blaring -- to create the oceans."

Frank's assertion and evidence that each year some 10 million icy comets, each averaging sixty compact cars in weight, strike the earth's atmosphere and, in the fullness of time, help fill the ocean basins.

If this belief is correct, meteors darting into the earth's upper atmosphere would have speeds less than 260,000 kilometers per hour. Any objects with significantly higher velocities must come outside the solar system. It has, therefore, been unsettling to find that quite a few meteors hit our atmosphere at speeds much higher than 260,000 km/hr. Radar measurements of 160,000 meteors by A. Taylor and colleagues, at a New Zealand site, found that about 1% (1500 meteors) struck the atmosphere with velocities greater than 350,000 km/hr. These speedsters must come from beyond the solar system. The question arising is: Whence all this interstellar debris? One hint comes from the fact that the aliens appear to come from the direction in which the sun and its family of planets are traveling through interstellar space. Evidently, this interstellar medium is far from a vacuum; it is strewn with flotsam and jetsam -- but from what smashed planets, moons, and asteroids?

So wrote R.W . Service, the poet of the Arctic realms, about the eerie voices of the auroras. The low-frequency sound of the aurora is barely detectable by human ears. It is "felt" more than heard, as Service expressed so eloquently. Some skeptics have maintained that these ethereal sounds do not really exist, but modern instruments confirm that pressure waves are definitely produced in the atmosphere as the auroras weave and dance in the sky. Most auroral sound is in the infrasound range, which begins at the lower limit of human hearing -- about 20 Hertz. Just enough sound energy seeps over the 20-Hz limit to be heard by sensitive human ears during periods of intense activity. Another natural infrasound, weak but continuous, is the "voice of the sea." These sound waves, called "microbaroms," have periods in the 5-7 second range (0 .20-0 .14 Hz), well below the range of human ears. Such low-frequency sounds travel great distances with little attenuation. It is thought, therefore, that the "voice of the sea" is an extended source -- perhaps the collective acoustical signature of all the storms from all the world's oceans. ...

The Leonids are meteors that radiate from a point in the constellation Leo. The millimeter-size bits of debris that create this annual light show are tiny fragments discarded by the comet Temple-Tuttle that burn up high in the atmosphere. Astronomers are secure and comfortable with this explanation of the mid-November spectacle. Perhaps they shouldn't be. In November 1998, an intriguing anomaly cropped up -- way up, 120 miles up! Leonids were seen to burn up at this altitude where there is not enough atmosphere to create the friction required to vaporize the space debris. Perhaps the cometary fragments from comet Temple-Tuttle are unusually volatile. Perhaps there is something else going on at the outer fringes of the atmosphere. Who knows? (Witze, Alexandra; "Scientists Gain Insights into Meteors," Northwest Florida Daily News, May 27, 1999. Cr. B. Reid) Comments.

Below, we present three examples where finality (closed books) seems to be proclaimed too quickly. On occasion, the night side of Venus (which goes through phases like the moon) seems to glow softly and subtly. For some 350 years, keen-eyed observers have seen this phenomenon through their telescopes. Nevertheless, the effect is so elusive that many astronomers doubt its physical reality. Additionally, it is easy to doubt the existence of the ashen light because good explanations are as elusive as the light itself. During the past decade, two scientific nails have also been driven into the ashen-light coffin: Spectrographic studies of the upper atmosphere of Venus do detect some nighttime air glow, but it is much too weak to account for the abundant telescopic observations from earth. The Cassini spacecraft did not detect any high-frequency radio noise typical of lightning when it passed close to Venus in 1998 and 1999. This put an end to the surmise that the ashen light was due to rapid, widespread lightning occurring deep inside the planet's thick atmosphere and then blended into a steady glow by atmospheric scattering. (Anonymous; "Case for 'Ashen Light' Weakens," Sky & Telescope, 101:27, May 2001.) Comment.

(SF#112, 114, 118, and earlier) Although some other data supported Frank's theory, many scientists scoffed. After some mildly acrimonious debate, a consensus decided that the spots on the satellite photos were merely instrument artifacts. Any lingering doubts as to Frank's house-size snowballs or "icy minicomets" impacting our atmosphere have been dispelled by a radar search by S. Knowles and his colleagues at the Naval Research Laboratory. Using the Naval Space Surveillance System's powerful radar, their scans of the upper atmosphere detected nothing resembling giant snowballs.

The central, flattened vegetation is crushed clockwise about half the time, counterclockwise in the other cases. On two known occasions, the flattening process has actually been observed. The invisible atmospheric vor tex does its work in 30 seconds or less and generates a high-pitched humming sound. The complex nature of these vortices is attested to by the rare ringed circles and multiple patterns. Both single- and double-ringed circles are known. The wind direction always alternates from central circle to first ring to second ring. The most common multiple patterns consist of large central circles flanked by two or four, smaller satellite circles, all nicely spaced.

We mentioned this conundrum briefly in SF#125. We now have the scientific details at hand concerning the supporting observations made during the November 1998 Leonid bombardment. The observations were made by an international team in China. Photographic cameras were employed as well as an all-sky TV camera equipped with an image intensifier. All photographed meteors began to visibly burn up below 130 kilometers, but the TV camera consistently picked up the same meteors at higher altitudes. Both sets of cameras recorded the same final burn-up heights. The most startling observation was a meteor that the TV camera detected at roughly 200 kilometers altitude. The highest observed Leonid meteor with initial mass of about 1 kg started radiating at an altitude of almost 200 km.

In addition to the volcanic activity and climate change, the shock of the asteroid impact could have been sufficient to destabilize the immense amounts of methane hydrate that have long been locked up, frozen and dormant, in oceanic sediments all over the world. According to this scenario, once the shock of the asteroid impact released the methane from its icy prison, it rose to the surface of the oceans in a world-wide burp. Methane, unfortunately for the dinosaurs and many other life forms, is highly flammable. Lightning could have ignited it almost immediately if it was concentrated enough.

"Several nights through the week were marked by strange atmospheric effects which Dr. Norman Lockyer of the South Kensington Solar Physics Laboratory believes to be a display of the aurora borealis, though personally I have not observed any colored streamers. "Following sunsets of exceptional beauty and twilight effects remarkable even in England, the northern sky at midnight became light blue, as if the dawn were breaking, and the clouds were touched with pink, in so marked a fashion that police headquarters was rung up by several people, who believed a big fire was raging in the north of London." (Anonymous; "Like Dawn at Midnight," New York Times, July 5, 1908. Cr. M. Piechota) Comment. Actually, all of northern Europe saw a succession of very bright nights beginning June 30, 1908. It was even possible to take photographs at midnight. The cause was not the aurora borealis but rather the Tunguska Event (Siberian Meteor) of June 30, 1908. Of course, Western Europe did not know what had happened in Siberia for years. Terrestrial dust from the Tunguska Event that was blasted into the upper atmosphere or perhaps particulate matter accompanying the impacting object (probably a comet) was apparently the cause of the nightime airglow.

This is the Novaya Zemiya Effect, and it is basically a polar mirage. Even when the sun is still 5 below the horizon, its light can become trapped between thermoclines and be transmitted over the usual horizon. The atmospheric ducts act much like flat light pipes. In the Novalya Zemlya Effect the sun's image is grossly distorted, quite different from the high quality mirages sometimes seen over hundreds of miles in the polar latitudes.

Looking up "choke damp", it is found to be "a suffocating gas, chiefly carbon dioxide, found in wells, coal mines, and other pits, also called "blackdamp." Evidently, in the quotation in SF#102 describing the death of one Donald Tollett due to a stythe, the word "stythe" was used for the meteorological event itself rather than -- correctly -- for the gases sucked out of the coal mine by a sudden drop in atmospheric pressure. (Stepp, Richard; personal communication, November 26, 1995) Comment. Changes in atmospheric pressure are also the causes of "blowing caves" and "weather wells". See GHG2 in Earthquakes, Tides, Unidentified Sounds. To order, visit here . Incidentally, blowing caves were used in the very early days of aernonautics for testing aircraft models due to the lack of wind tunnels.

... Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Mercury's polar caps and icy minicomets Mercury, closest planet to the sun, should be baked bone dry, seeing that equatorial temperatures reach 800 F. When Mariner 10 flew past Mercury in 1974, its camera eye reinforced the baked-cinder model. To everyone's surprise, recent radar images obtained with powerful earth-based antennas, revealed a highly reflective patch at Mercury's north pole. Could it be ice, for ice reflects radar waves well? Quite possibly, for when Mercury's polar temperatures are calculated, away from the sun's direct glare, they plunge to -235 F. This means that some of the water vapor in the planet's thin atmosphere might freeze out in the poles, creating ice or frost caps. Wouldn't Mariner 10 have seen such a remarkable deposit? Not necessarily, for the spacecraft viewed only half the planet and, if the 640 x 300-kilometer ice patch were covered with dust, it could have been invisible to the camera. But it would still be a bright patch on terrestrial radar scopes, because radars see through thin dust layers. So, polar ice is not physically impossible on Mercury, although it is defi nitely surprising so close to the sun. All that is needed is a little water in the planet's atmosphere. Mainstream thinking is that "passing comets and asteroids" might bequeath Mercury some of their H2O cargos. (Cowen, R.; "Icy Clues from ...

Science Frontiers ONLINE No. 95: Sep-Oct 1994 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects This was the big one, but where did it come from?October 15, 1991. American Southwest. Photomultipliers in the Fly's Eye telescopes 100 kilometers southwest of Salt Lake City recorded the havoc wrought in the upper atmosphere by the most energetic cosmic-ray particle ever measured. When this tiny subatomic particle slammed into air molecules, the ensuing debris caused the surrounding atmosphere to fluoresce. The amount of light produced indicated that this cosmic ray had an energy of 3 x 1020 electron volts -- that's equivalent to the energy of a bowling ball dropped from waist level. Now that's a lot of energy for a subatomic particle! Because cosmic rays normally lose energy as they collide with photons in their cosmic wanderings, astrophysicists believe that "the big one" had to have a recent, nearby origin in order to still be so energetic. But no one has any idea where it could have come from or how it might have acquired so much energy. Somewhere out there in nearby space there may be a natural particle accelerator orders of magnitude more powerful than our biggest earthbound atom smashers. (Anonymous; "The Deepening Mystery of Cosmic-Ray Origins," Sky and Telescope, 87:12, May 1994.) Comment. Actually, the source of "the big one" need not have been nearby and recent. All anomalists will recognize that this is an assumption based upon the particle ...

... Science Frontiers ONLINE No. 29: Sep-Oct 1993 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Life beyond 100 c Bacteria can survive and multiply in hot springs near and slightly above 100 C -- the boiling point of water at atmospheric pressure. Few scientists have contemplated the possibility of life forms prospering at temperatures well beyond 100 . Recently, however, the discovery of many new and frequently bizarre organisms clustered around deep-sea vents has forced a reexamination of high-temperature life. It seems that bacteria actually flourish in the 350 C water streams from the deep-sea vents. In the lab, these same bacteria multiply rapidly in water at 250 C kept liquid by pressures of 265 atmospheres of pressure. What a surprise! Quoting a concluding sentence from this article: "This greatly increases the number of environments and conditions both on Earth and elsewhere in the Universe where life can exist." (Baross, John A., and Deming, Jody W.; "Growth of 'Black Smoker' Bacteria at Temperatures of at Least 250 C," Nature, 303:423, 1983.) Comment. Ignoring for the moment the extraterrestrial possibilities, the earth is riddled like a Swiss cheese with hot, fluid environments, which we may now consider potential abodes of life. Subterranean life represents a new biological frontier. Who knows what kinds of organisms have developed to feed upon the planet's heat? Could they have con-tributed to our supplies of petroleum and natural gas? From Science Frontiers # ...

... Science Frontiers ONLINE No. 114: Nov-Dec 1997 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects It can't be true because it violates our ideas!This was the collective opinion of many atmospheric scientists when a satellite experiment found approximately 50% more water vapor at an altitude of 75 kilometers than well-established theory predicted. That was back in 1991. Now, a second satellite experiment of different design has confirmed the existence of this "excess" water vapor. Most geophysicists are perplexed, to say the least. Not L. Frank, though, because these experiments are in line with his theory that the upper atmosphere is continuously pelted by house-size, fluffy, icy comets -- some 20 each minute. (SF#112) Frank asserts: "When you get that excess of water vapor up there, it just can't come from the Earth. It must come from space." Even so, other geophysicists are reluctant to accept Frank's icy comets -- that would be too much "crow" to eat! One point levied against Frank's icy comets is that they would introduce more than three times the amount of water vapor actually measured. M. Summers, a theoretician at the Naval Research Laboratory, summed up mainstream opinion: "There's definitely something very unusual going on in the mesosphere that we don't understand at all, but I'm not even close to saying this supports the small-comet hypothesis."

Channon's sketch of the "Face on Mars" emphasizing its similarities to the Sphinx. (From: Pozos, Randolfo Raphael; The Face on Mars , Chicago, 1986, p.50) Once again we return to cold, desertlike Mars, which still clings to a thin, oxygen-less atmosphere and where, some say, the artifacts of a long-dead intelligent race may be seen. A livable Mars in past eons is not a physical impossibility. Some scientists argue that Martian geological and geochemical data: ". .. are consistent with past conditions on Mars that were favorable to earth-like life forms: Abundant liquid water and an atmosphere that was dense and warm, and possibly rich in oxygen." That life -- intelligent life -- once thrived on Mars is suggested by photos taken of the Martian surface by Viking spacecraft: "Images of the surface of Mars showing, at several sites what appear to be three carved humanoid faces, of kilometer scale, and having similar anatomical and ornamental details between all three. Appearing with these objects are numerous other objects and suface features that resemble Earth-like archaeological ruins, of a Bronze Age culture, with no evidence of advanced technology or civilization." The Martian faces, pyramids, and cities are the foundation of the Cydonian Hypothesis: "That Mars once lived as the Earth now lives, ...

Science Frontiers ONLINE No. 7: June 1979 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects The sun controls the earth's global electrical circuit Data collected from electrosondes (balloons measuring atmospheric electrical currents) over the Antarctic ice caps infer that solar flares stimulate large surges in the flow of electrical charge from the upper atmosphere to the earth's surface. Because this unidirectional flow of fair-weather electricity must ultimately be balanced by thunderstorms somewhere on the planet, it follows that the frequency and severity of terrestrial thunderstorms are dictated, at least on the average, by solar activity. Formerly, global circuit theory had it that the thunderstorms themselves were the driving force behind the fairweather current flow. Now it seems that the sun calls the tune and that thunderstorms do not arise at random. (Anonymous; "Solar Activity and Terrestrial Thunderstorms," New Scientist, 81:256, 1979.)
