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.

Science Frontiers ONLINE No. 43: Jan-Feb 1986 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Waiting for saturn's rings to collapse The more we learn about Saturn's rings, the stranger they seem. One of the latest theoretical models of the rings has them composed of balls of hard ice, which interact through mutual collision and are herded by the gravitational caresses of small moons. The successes of this model have been tempered by the fact that it also implies that Saturn's rings are very young. "Theorists would have no problem with a broad, featureless disk surviving the 4.5 billion years since the early days of the solar system, but features such as spiral density waves are clear evidence that satellites, including the profusion of small ones found near the rings, are draining angular momentum from the rings. The satellites should be spiraling outward into ever larger orbits as they gain angular momentum, and the A-ring should collapse inward into the B-ring in just 100 million years as its particles lose angular momentum." (Kerr, Richard A.; "Making Better Planetary Rings," Science, 229:1376, 1985.) Reference. For other indications of youth in Saturn's rings, see ARL16 in our catalog: The Moon and the Planets.

... Project Sourcebook Subjects Neptune's partial rings Neptune's rings cannot be seen directly. Instead, earth-based astronomers watch for occultations or dimmings of stars as they pass behind the rings. This seems straightforward enough in theory, but the occultations have been perplexing in practice. First, one member of a closely spaced double star will be occulted normally by the rings but its companion won't . Second, some terrestrial observatories will record an occultation but another a few thousand miles away will not. Such experiences have led to the hypothesis that the rings are discontinuous; that is, they are arcs rather than complete rings. Why should Neptune's rings be different from those of the other major planets? On speculation maintains that the arcs are the consequence of one or more recently satellites. Another hypothesis, by J.J . Lissauer, has the arcs gravitationally shaped and maintained by two moons, one of the shepherd type (as with Saturn's rings), the other at a Lagrangian point in the arc's orbit. (Kerr, Richard A.; "Neptune's Ring Arcs Confirmed," Science, 230:1150, 1985. Also: Lissauer, Jack J.; "Shepherding Model for Neptune's Arc Ring," Nature, 318:544, 1985.) Comment. The theories employing "shepherd" moons to gravitationally mold and maintain planetary rings have been weakened by the apparent absence of such bodies at the theoretically necessary locations around Saturn and Uranus. Also relevant is the possible youth of Saturn's rings. ...

One eyewitness account of the formation of a single spial pattern has been found. However, the multiple spiral patterns excite the most interest because of their geometric regularity. Between 1980 and 1984, eight quintuplet patterns have been found consisting of a large central circle and four smaller satellite circles. Triplets were also discovered. Although the origins of the multiplet patterns are still unexplained, some interesting generalizations have emerged: 1. The whirlwinds responsible for the flattened circles of crops have lifetimes of only a few seconds, whereas dust devils may persist for many minutes; 2. These whirlwinds seem to occur around evening time instead of during the heat of the day; and 3. They are all anticyclonic, while tornados are almost all cyclonic and true heat whirlwinds are split about evenly in their spin direction.

Frank, at the University of Iowa, had detected dark spots on satellite images of the earth's dayglow. Frank thought that the spots might be due to clouds of water vapor released as small, icy comets hit the atmosphere. P. 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." Naturally, such a theory is very disturbing because it runs counter to the widely accepted idea that the oceans were created by the ...

Stolarski and colleagues at NASA's Goddard Space Flight Center have seen the concentration of ozone over Antarctica drop dramatically -- some 40% -- every October. This disappearing act commences about a month after the sun begins to graze the northern horizon and affects the entire continent. By early November, the sun is high enough to manufacture enough ozone via its ultraviolet radiation to fill the ozone hole up again. An analogous hole does form over the North Pole in the northern spring. An additional fact of interest: the hole is getting deeper each year; that is, the ozone concentration is less and less each October. Speculations about the deepening seasonal hole involve the widespread use of chlorofluorocarbons and Antarctica's physical isolation from other land masses which would help channel ozone southward from areas where the sun still shines.

Some of the raised fields are remarkably sophisticated in design. At the base is a layer of cobblestones for stability. These are covered by a 10-centimeter layer of clay. On top of the clay are three distinct layers of sorted gravel; all capped by rich organic topsoil. These fields were simultaneously an aquifer for the fresh water percolating down from the surrounding hills and a barrier to the brackish water from Lake Titicaca. Even at Tiahuanaco's altitude, these fields could have grown potatoes, oca, or ulluco and the chenopod grains, as well as quinowa and caniwa. Tiahuanaco and its satellite cities could have been fed with enough left over for export. Not bad for farmers 2,000 years ago!

Science Frontiers ONLINE No. 44: Mar-Apr 1986 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Atmospheric Footprints Of Icy Meteors Serendipity triumphs again. 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 ...

"The clouds dissipate in a few hours vanishing as mysteriously as they appear. "Among the plumes are a series of massive clouds that during the past four years have periodically swelled over Novaya Zemlya, the Arctic island long used by the Soviets for nuclear weapons tests. "However, there appears to be no correlation between the clouds and known Soviet tests, which are usually detected by Western governments. Further, non-governmental scientists said the 200-mile-long plumes appear to be many times larger than the largest conceivable nuclear explosion could produce." A NOAA satellite detected a large plume coming from the Arctic Ocean near Bennett Island, north of the Soviet Union, in 1983. Three distinct sources were found; one on the island and the other two about 9 miles offshore on the ice-covered ocean. This plume was 6 miles wide, 155 miles long, and 23,000 feet high.

In this paradigm, the brain stores memory and deals with interactions by interpreting and integrating frequencies, retaining the data not in a localized area but dispersed throughout its substance."

... above assumed ordinary matter. Perhaps there are inhomogeneities on a different, more basic level -- matter vs. antimatter. According to one popular theory, the universe began with equal amounts of matter and antimatter. If so, where did all the antimatter go? We assume we observe a universe that is virtually 100% matter. Of course, we cannot really tell for certain because an antimatter galaxy would appear to us just like a galaxy composed of ordinary matter. The only clues revealing substantial pockets of antimatter would be the annihilation radiation produced where matter and antimatter regions rubbed against one another. The two types of matter always annihilate one another in bursts of very distinctive radiation. Well, there seems to be at least one region of antimatter near the center of our galaxy. The HEOS3 satellite and ballon-borne instruments have pinpointed a source of 511 kev gamma rays that can come only from a spot where electrons and positrons are mutually annihilating each other. (The positrons are antimat-ter analogs of electrons.) This region of mutual destruction is about 1013 kilometers across. Is it a pocket of antimatter left over after the Big Bang that a sea of surrounding matter is finally wiping out, or is it newly created antimatter in the vicinity of a black hole? No one knows. The mystery has deepened with the discovery that the intensity of the annihilation radiation varies with time. Something strange is going on out there.

This startling conclusion was reached by Donald Clayton of Rice University after studying observations of the amount of aluminum-26 (26Al) in the interstellar medium." Instruments on satellites (gamma-ray spectrometers) have detected so much aluminum-26 that radical hypotheses seem required. The problem is that aluminum26 is radioactive with a half-life of only about 1 million years -- a very short time astronomically speaking. The aluminum-26 cannot be primordial solar-system stuff; it cannot even be 10 million years old. It had to be created somewhere nearby recently. The best aluminum-26 factory conceived so far is a nova in our vicinity. (Anonymous; "Are We inside a Supernova Remnant?" Sky and Telescope, 69:13, 1985.) Comment.

Eleven such events are tabulated from October 12, 1980, to June 12, 1986. Perhaps the most dramatic event occurred on March 12, 1982, over Novaya Zemlya. The picture shows a sharply etched tongue of cold vapor arcing some 175 kilometers at a maximum altitude of 9.5 -10 kilometers. As with most of the plumes, movement of the vapor does not correspond to wind direction. Volcanic activity and natural methane gas releases are considered unlikely explanations. Since the islands involved are used for Soviet weapons tests, the plumes may be due to some incredibly energetic devices, although no radioactive releases or seismic activity seem correlated with the plume appearances. Queries to Soviet scientists have gone unanswered. (Anonymous; "Large Plume Events in the Soviet Arctic," Eos, 67:1372, 1986.) From Science Frontiers #50, MAR-APR 1987 . 1987-2000 William R.

With sophisticated terrestrial and satellite-borne instruments, they have detected gamma-ray, X-ray, and infrared bursters. The visible portion of the spectrum has been neglected because of the slow development of sensitive, high-time-resolution detectors capable of monitoring large areas of the sky. Of course, the human eye is an excellent instrument for searching for optical bursters, but professional naked-eye astronomers are few and far between nowadays. It has fallen to amateur astronomers to pioneer this field, as first mentioned in SF#39, where we introduced those optical flashes seen in Perseus. At last, the professional astronomers are taking more interest in this class of bright, unexplained flashes in the night sky. Those amateur astronomers, with their "primitive" instrumentation, have actually had a paper published in the highly technical Astrophysical Journal. Their abstract follows: "Between 1984 July and 1985 July, 24 bright flashes were detected visually near the Aries-Perseus border by eight different observers at a total of 12 sites across Canada. One flash was photographed, and another was seen by two observers at different locations. Their duration was usually less than 1 s.

At the same time, 1983 proved to be a bumper summer for the production of 'mystery spirals' (and for heat whirlwinds generally). Moreover, and entirely unexpectedly, some of the spiral formations turned out to be symmetrically complex systems in an extraordinary manner: as many as four sets in different parts of southern England were found to consist of a single circle attended by four smaller satellite ones. "The beauty of these sets of circles caught the attention of the national newspapers, and thence the imagination of the general public.

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.

The officers of the Baron Pentland picked up the object with binoculars and sextant. "First thoughts were that this was the satellite Cosmos 1402, but this was dismissed as it was a day too early and it was not moving fast enough. In fact it appeared stationary to the naked eye. Another school of thought was that this was a weather balloon. As can be seen from the simple sketch, it was unlike any weather balloon previously seen by the observers. It was of a squat cylinder shape, wider than it was tall. The circle at the bottom appeared to be dimly lit with a pale blue colour. The 'torso' was almost invisible, even with binoculars, giving the impression that there were two distinct and separate lights. The top 'light' appeared to be a dome atop the main body and it was extremely bright.

The ring system of Uranus was discovered by studies of similar stellar occultations. Sure enough, astronomers at the European Southern Observatory, in Chile, and the Cerro Tololo Observatory, also in Chile 90 kilometers away, detected a 1-second, 35% reduction in the star's light at the same instant. These data indicate the presence of an object 10-20 kilometers wide -- hardly an undicovered satellite, but possibly a ring. But given the geometry shown, there should have been two occultations, but only the one on the right was registered. Speculation is now rife that Neptune has a partial ring or a grotesquely twisted one. (Eberhart, J.; "Signs of a Puzzling Ring around Neptune," Science News, 127:37, 1985.) Comment. Of course the geometry of the ring could have been such that the star was tangent at one point.

I ran outside to see what it was, but saw nothing; the noise was something like the sound of a falling bomb. I thought no more of this until the following morning when taking my dog for a walk. Then I saw two large circles, about 25 feet (7 .6 metres) in diameter, of flattened barley in a nearby field. A neighbor who lives on the north side of the ridge had also heard the roaring noise but could find no cause for it. I wondered if we had heard some part of an aircraft or satellite, or even a small meteor, coming down and, with the local farmer, we investigated the circles, but found no debris at all -- just flattened barley. The farmer said that sometimes growing conditions made barley collapse at its base, though he could not understand the almost perfect circle." Further investigation turned up people who had seen a whirlwind in the area at the time. (Anonymous; "Mystery Spirals in Cerealfields," Journal of Meteorology, U.K ., 8:216, 1983.) Comment.

In addition, there are unexplained perturbations in the orbits of earth satellites, peculiar periodicities in the sunspot cycle, and equally puzzling regularities in earthquake frequency. Infrared detectors have also picked up unidentified objects in the sky. These anomalies might all be explained by the existence of a large, dark planet with several moons -- or, if the mystery object turns out to be very far away, by a very large, dark stellar companion of our sun with its own system of planets. Several astronomers have been trying to pin down the properties of this Planet X or Massive Solar Companion (MSC). John P. Bagby has recently published a novel solution to this nagging puzzle in celestial mechanics. He suggests that the Massive Solar Companion is actually a distributed system; that is, appreciable mass also occupies the several stable Lagrangian points. The total MSC mass might be as much as half the sun's mass, perhaps 100 Astronomical Units (100 times the earth's distance from the sun.) If the MSC and its attendants are this massive, astronomers will have to revise the mass and density of the sun downward by a good bit. (What they have done in the past is estimate the mass of the solar system as a whole and assumed it mostly resides ...

Initially, the grooves were thought to be fracture lines formed by the impact that blasted out Stickney, the huge crater seen on Phobos. However, studies of the grooves revealed at least three families of grooves of different ages, with members of each family located on parallel planes cutting right through the body of the satellite. Two recent papers have proposed radically different explanations. A. Horvath and E. Illes wonder whether Phobos might not be a layered structure, having once been part of a larger stratified body. J.B . Murray thinks the families of grooves might have been scraped out by disciplined formations of meteorites that were launched into space by Martian volcanos. (Horvath, A., and Illes, E.; "On the Possibility of the Layered Structure of Phobos," Eos, 62:203, 1981. Also: Murray, J.B .; "Grooved Terrains on Planetary Satellites," Eos, 62:202, 1981.) Comment.

By comparing the times of arrival of the burst, the direction of the source was narrowed down to a "box" a couple of arc minutes across. Gamma-ray bursts have never before been correlated with visible sources, but this time the box contained the remnants of a supernova in the Large Magellanic Cloud, a satellite galaxy of our own Milky Way. The anomaly that arises involves the immense distance of the supposed source and the strength of the burst when it reached the solar system. The power level of the supernova remnant gamma flash would have had to be about 1037 watts -- a stupendous figure. If the supernova remnant is a neutron star, as current theories suggest, the neutron star would have to be 10 to 100 times the size of the usual neutron stars.

Their thesis is that the solar system periodically passes through the regularly spaced spiral galaxy arms every few 107 years. Planetesimals in these arms cra-ter the solar-system planets at these times and also provide the raw materials for new comets, asteroids, satellites, and even planets. Supporting their theory is the repeating history of geological revolutions with the accompanying extinctions and reflowerings of life. A remarkable feature of this paper is a table of shortlived solar-system phenomena (comets and rapidly evolving staellite-and-ring systems). The tenor is one of episodic catastrophism and a rapidly changing solar system; viz., Saturn's rings evolving in only 104 years.

New cosmic X-ray data from the satellite Ariel 5 suggests that a large, hitherto unsuspected mass is located in the same direction that the earth is moving. Thus, both X-ray and microwave data could be explained by supposing this mass to be large enough to pull the earth (and our Galaxy) toward it. This mass would have to be about 10 billion light years away and weigh as much as 100 million Galaxies. Such a gigantic blob or inhomogeneity in the universe would be very difficult to explain. As it is, the aggregation of stars into galaxies after the Big Bang remains poorly understood. The bigger the inhomogeneity, the harder it is to account for.

Some of the time, but not always, Io emerges from the shadow about 10% brighter than when it entered. In 10-20 minutes, its brightness decays to normal levels. One suspicion is that SO2 in Io's atmosphere condenses on the planet's surface when it is in the cold shadow, thus coating some dark areas with a bright sulfurous 'frost.' However, a recent measure of Io's post-eclipse brightness detected no brightness change whatsoever. Apparently we have a real but rather unreliable phenomenon.

Long a controversial phenomenon, this confirmation of Io's post-eclipse brightening has led to a search for possible explanations. Witteborn et al suggest that the transient flare-up is a complex thermoluminescent effect excited by interaction with Jupiter's magnetosphere, followed by solar heating as Io emerges from the shadow.

First, if they are made up of small chunks of matter, the laws of celestial mechanics dictate that they should quickly spread out radially into much wider rings in just a decade or two. In other words, if the rings are ancient they should not have maintained their present form. Second, the rings are invisible when one would expect them to be bright like Saturn's . Yet, they reflect less light than the blackest coal dust. T.C . Van Flandern proposes that each ring is actually a single satellite, so small that we cannot see it, and that it sheds gases as it orbits. This small solid body would make the celestial mechanics people happy, and the gases would be invisible to the eye but still absorb light, making the ring of gases detectable when Uranus occults a star. (Van Flandern, Thomas C.; "Rings of Uranus: Invisible and Impossible?" Science, 204:1076, 1979.) Comment. An alternative explanation is that the rings are recently acquired and will soon disappear.

A large fraction of the superbolts are recorded over Japan and the northeast Pacific during intense winter storms.

Enough high-resolution photos have been taken to prove that these grooves emanate from the large crater named Stickney and run around the satellite to its opposite side where they die out. This suggests that the origin of the crater and the grooves are related. Further, the widest and deepest grooves (700 meters wide and 90 meters deep) are located close to Stickney. On the other side of Phobos, grooves are consistently less than 100 meters wide. Despite these hints of impact origin, the grooves are not quite what one would expect from simple fracture by collision. Some show beaded or pitted structures. Other grooves are composed of irregularly bounded segments. Finally, some of the straight-walled sections seem to have slightly raised rims. Evidently, some internal forces, perhaps stimulated by the formation of Stickney, also played a part. (Thomas, P., et al; "Origin of the Grooves on Phobos," Nature, 273:282, 1978.) Reference.

Well, L. Frank, University of Iowa, did just that in 1986. He was duly pilloried for his trouble. But, at the 1997 spring meeting of the American Geophysical Union, Frank presented new data to back up his previous assertions. The most startling of his new evidence came from a camera aboard a NASA satellite. Time-lapse photos imaged two objects streaking into the atmosphere over Poland and Germany. Frank identified these as clouds of water molecules from disrupted icy minicomets. The clouds had expanded from the house-size minicomets to clouds 3550 miles wide, weighing 20-40 tons. Frank thinks the minicomets come from a cloud of such objects orbiting the sun from earth out to Jupiter and beyond. Why don't they evaporate in the sunlight and near-vacuum of outer space?

But, it is possible that light could reach it through the ears by diffusing through the soft, translucent tissues that lead into our skulls. A commercial opportunity arises here. Jones notes first that melatonin is a mood enhancer and stimulant. We all have read how depressed far-northern peoples become during their long winter nights; and we know first-hand how exuberant we are on bright spring days. Why not, asks Jones, manufacture "earlights" mounted on headbands? These would direct red light (which diffuses better through tissue) into the ears and thence to the pineal gland. People could thereby be made cheerful and enthusiastic whatever the season, weather, or time of day. We could dispense with all those mood-enhancing pills.

Science Frontiers ONLINE No. 113: Sep-Oct 1997 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects An exploded planet and the "face on mars"Between Mars and Jupiter swirls the main main asteroid belt. In the view of many astronomers, including T. Van Flandern, there resides the debris of an exploded planet. Van Flandern has adduced considerable evidence supporting the exploded planet hypothesis, which we will pass over in favor of a look at the possible effects of said exploding planet upon a large but equally hypothetical satellite of said planet. Such a satellite would have been heavily pelted by debris on the side facing the exploding planet. Furthermore, this battered sphere, having lost its gravitational "anchor," would assume a new orbit around the sun as well as a new orientation in space. Is there any object in the solar system plastered mainly on one side with debris and craters? You guessed it: Mars! What possible connection could there be between this purported cataclysm and the "face on Mars"? The connecting thread is very weak but so beguiling that we must mention it. T. Van Flandern has proposed eight tests for the artificiality of the "face" and its associated "pyramids," "city," etc. One is the three-dimensionality of the "face." Another is the "fractal" test, which is useful in distinguishing between artificiality and naturalness. The "face" readily passes four of the eight tests. A fifth test (bilateral symmetry) cannot be decided ...

North Atlantic Ocean. Aboard the s.t .s . Astrid enroute from the Azores to Dartmouth. "At 0443 UTC a light was sighted high in the sky above the ship. The light was of the style of a satellite in appearance. However, it was seen for about 10-15 seconds moving west to northwest, with a pulsating white light. In addition, it was moving very fast and it also stopped dead a couple of times. "At one point, the light stopped and turned in the direction of the ship. The light no longer pulsated, and for about one second it was in the form of a spotlight lighting the surrounding area. The light then turned back again and moved very, very fast across the sky before it was lost below the horizon in a matter of seconds." (Ulrich, G.; "Unidentified Light," Marine Observer, 68:64, 1998.) Comment. The erratic motion and use of a searchlight are typical of some of the UFO reports seen in newspapers. However, the Marine Observer is a publication of the UK Meteorological Office. In the above "encounter," aircraft, satellites, and meteors do not fit the testimony of the observers.

... 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."

In fact, it is the largest vertical rock free-fall ever recorded seismically and it registered on seismographs up to 200 km distant." (Uhrhammer, R.A .; "Seismic Analysis of the Yosemite Rock Fall of July 10, 1996," Eos, 77:508, 1996.) December 9, 1995. Southern Ecuador. "On the afternoon of December 9, 1995, a bolide exploded in the atmosphere over the Andes in southern Ecuador. Many people in nearby towns witnessed the event. They reported seeing a streaking meteor, which terminated in a loud and brilliant explosion. In some locales, the flash was noticeable even through cloud cover. The burst of light was observed by satellite optical sensors used to detect atmospheric nuclear tests. Three local seismic stations also recorded signals from the explosion...This bolide appears to be unique in that it was observed by eyewitnesses and located by both satellite and ground-based sensors." The sound of the meteor's explosion was heard at least 56 kilometers away. (Chael, Eric P.; "Seismic Signals from a Bolide in Ecuador," Eos, 77:508, 1996.)
