At this point in its trajectory, it came into the field of view of the X-ray astronomy satellite ROSAT. ROSAT was designed to look at stars whose extremely high temperatures can generate X-rays. It seemed ridiculous to point ROSAT's instruments at a comet composed mainly of ice and dust. How could a comet emit X-rays? When a German-American team of scientists proposed taking a peek at Hyakutake with ROSAT, scientific eyebrowns were raised. What a waste of observing time! At the most, the team thought they might pick up a smudge of weak X-rays where dust grains flying off Hyakutake collided with dust grains normally present in interplanetary space. The team did get ROSAT to take a look, and what the satellite saw ignited a controversy. Some 50,000 kilometers in front of the comet was a bright crescent of X-rays, 100 times brighter than the brightest "smudge" the team of scientists had hoped for. This was completely unexpected. All astronomers could do was come up with three rather unconvincing theories: (1 ) Solar X-rays were absorbed and reemited by the comet (Xray fluorescence); (2 ) Cometary material emitted X-rays when bathed in the solar wind; and (3 ) Charged particles were ...

Expanding along these lines, whole star systems could be 100% Mirror Matter, and we'd never see them at all.

This was the time of the well-publicized, but still hypothetical, asteroid impact. It is said to have wreaked havoc on our wounded planet and, especially, the dinosaurs. Volcanos spewed out vast lava fields and filled the air with greenhouse gases and dust. It was a bad time for many life forms. Actually, It may have been far worse than generally advertised. 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. A colossal firestorm might have then enveloped the entire planet. The whole atmosphere could have been afire. This, according to B.

In fact, there seems to be a great dearth of small, cool, solid, water-and-carbon-rich planets circling beneficent suns. Can it be that we are looking for extraterrestrial life in the wrong places? Life may have originated and prospered on the multitude of sun-less aggregations of matter drifting through the void, some doubtless quite close to us. Myriad nomadic planets may be roaming our Galaxy free from the clutches of parent stars. Two teams of astronomers think they have detected 25 of these free-floating planets, and say there could be hundreds of millions of them wandering the Milky Way. These free-floaters or "drifters" were created when small clouds of gas and dust coalesced under gravity's urging. If such collapsing clouds were less than 80 times Jupiter's mass, they would not be able to sustain nuclear reactions and become long-lived stars. Many would be-come "brown dwarfs." Still smaller aggregations -- less than 14 Jupiters -- would never shine at all. These would remain warm for a while as they dissipated the gravitational energy that created them. Such small objects would be temporarily detectable by infrared telescopes. Hundreds of such infrared "point sources" turn up in sky surveys. These are the only "drifters" we can detect.

Collectively, they record many meteor showers and fireballs; all quite respectable astronomical objects. But sometimes fuzzy, rapidly moving luminosities appear, as in the following paragraph written by J.S . Gallagher: "Diffuse luminous objects moving at angular velocities similar to those of meteors were observed during over 200 hours of meteor watching in 1991. They fell in three broad categories: arcs, patches, and 'meteors' similar in appearance to comet comas. Though I at first dismissed the possibility of their being related to meteors, I reconsidered this relation after eliminating other possible causes such as reflections from aircraft lights and tricks of vision. Their meteor-like behavior suggested that perhaps these events might be caused by clouds of exceedingly small meteoroids, visible only because of their numbers and compact grouping. Because such a formation would be unlikely to be maintained long in space, it appeared necessary that the particles involved must have maintained some weak physical contact until just prior to becoming visible. Perhaps some type of 'cosmic dust bunny,' disrupted by air resistance, might be the cause of these events." These moving patches of light also resemble the "auroral meteors" cataloged under GLA3 in Lightning, Auroras, Nocturnal Lights. Physically, they might be related to the small, icy ...

This debris layer (BIT-58) extends parallel to the stratigraphy of the ice established from the tephra bands, and thus apparently marks a single depositional event. Several kilograms of ice from two sites along this band were subsequently collected and melted, yielding a few grams of sediment for further study." Microscopic examination and microprobe analysis led to the following conclusions: "Although direct evidence of an extraterrestrial origin for this debris layer (such as the presence of cosmogenic 10 Be and 26Al) has not yet been obtained, the available data strongly suggest that this sediment originated as meteoritic spallation debris. This debris is distinct from other Antarctic 'cosmic dust' collections by virtue of its uniform, recognizable, ordinary chondrite composition and the consistent relation shown between grain size and texture.

The great diversity of the debris swirling around the solar system is making life difficult for scientists trying to reconstruct solar-system history. At the high end of the density spectrum, we now have an asteroid that seems to be mostly metal (probably iron). This is the asteroid Gaspra, some 13 kilometers across, that the Galileo spacecraft encountered in August 1992 on its way to Jupiter. Scientists had not expected Galileo's magnetometer to flicker as it passed Gaspra at a distance of 1600 kilometers -- but it did. In fact, considering the inverse square law and Gaspra's small size, it was a magnetic wallop. Thus, Gaspra is the first known magnetic asteroid; and it is probably mostly metal. (Kerr, Richard A.; "Magnetic Ripple Hints Gaspra Is Metallic," Science, 259: 176, 1993.) At the low end of the density spectrum, we now find that Pluto's moon, Charon, and some of Saturn's moons have very low densities (1 .2 -1 .4 ), meaning they are probably mostly water ice.

Proposed solutions to this riddle range from bacterial attack, to gritty saliva propelled through the teeth, to the overenthusiastic use of bone toothpicks. But Australian aborigines have provided a more convincing explanation.

... 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.

Let us take the excess-iron problem first. Mercury's density is 5.44 (compared to earth's 5.52), so that it very likely contains much iron. Our moon, which resembles Mercury in size and external appearance, only has a density of 3.34, implying an altogether different origin. In the currently accepted theory of solar-system formation, all of the planets and their satellites condensed from a primordial disk of dust sur rounding the just-formed sun. The planets closer to the solar inferno lost more of their easily vaporized constituents due to the sun's heat. The cooler, outer planets were able to retain large amounts of ices. In this scenario, we would expect Mercury to be rich in iron and rocks. This seems to be the case, but it has too iron to fit the theory. Astronomers have tried to save the theory by supposing that a large asteroid sideswiped Mercury tearing off part of its outer layer of lighter rocks, leaving the heavier iron core untouched.

Significantly, one circle formed in a field they had ringed with automatic alarms, making a hoax very unlikely.

First, a tad of background: Great meteor impacts and tektite events seem to have occurred nearly simultaneously with deep-cutting biological extinctions and reversals of the earth's magnetic field. Ever since this apparent synchrony was recognized a few decades ago, theorists have been vying in generating scientific scenarios, especially some mechanism that would reverse the earth's magnetic field.

The cold persists long after the dust settles because of the increased reflectivity of the snow-covered continents.

True, its orbit between Saturn and Uranus is unusual, but what else could it be but an asteroid? A comet, that's what! Recently, the brightness of Chiron has doubled, suggesting that it has expelled considerable gas and dust -- a characteristic of comets, according to mainstream thinking. Another peculiar aspect of the phenomenon is that Chiron is now located 12 A.U . from the sun (12 earth orbits out). Conventional wisdom has it that solar heating is too weak at that distance to vaporize cometary ices. However, other comets, such as Schwassmann-Wachmann 1, have displayed comas even farther away from the sun. Thus, we have two possible anomalies here: (1 ) The existence of a huge cometlike asteoid in a peculiar orbit (2 ) A mechanism that expels gas and dust from comets at great distances from the sun. The blurring of the distinctions between asteroids and comets is aggravated by the recognition that some other asteroids produce streams of particles that create meteor showers; that is, some asteroids are not merely associated with meteor streams, they actually create them, just as comets expel ice and rocky debris. Some bold astronomers now ask whether asteroids are all burntout comets. ...

Comets are supposed to be as old as the solar system itself (4 .6 billion years), born of solar-system stuff when a gaseous cloud condensed. Above all, comets do not "burn" or combust! The vision of a "burning" comet was advanced by recent observations that the velocity and temperature of the gases escaping from Halley are higher than one would expect from the sublimation of ices under solar radiation. Also, the concentration of expelled material in large, hypersonic jets carrying large quantities of fine dust further undermine the sublimation model. E.M . Drobyshevski has concluded "The new observations, together with some earlier data still poorly understood (e .g ., the appearance in the coma of large amounts of C3 ) can be accounted for by assuming the cometary ices to contain, apart from the hydrocarbons, nitrogen-containing compounds, etc., also of free oxygen (about 15 wt. %) . Under these conditions, burning should occur in the products of sublimation under deficiency of oxidizer accompanied by the production of 'soot,' 'smoke,' etc. The burning should propagate under the surface crust and localize at a few sites. "The presence of oxygen in cometary ices follows from a new eruption theory assuming the minor bodies of the Solar System to have formed ...

"It is concluded that on five occasions during the interval 20,000-14,000 years BP, cosmic dust mass concentrations in the solar system rose by one and two orders of magnitude above present day levels. Moreover if the particles found in these ice core samples are indicative of the particle size distribution which prevailed in the interplanetary medium at that time, then it may be concluded that the space number density of submicron sized particles must have uncreased by a factor of 105 or more. During these times the light transmission properties of the solar system would have been significantly altered resulting in major adverse effects to the earth's climate.

Swinn, formerly Chief Instructor for the Egyptian Gliding School, has had much practical experience with those fascinating little (sometimes not so little) swirls of hot air called "dust devils." Under the broiling Egyptian sun, dust devils launched themselves naturally every few minutes from a tented camp near the airfield where Swinn taught. Curiously, the devils often were born in pairs; a big one followed by a modest little chap following behind by 100-150 yards. The devils ranged from just a foot or so in diameter to 500 yards and more. The giants were majestic masses of swirling sand that moved along at leisurely paces.

Surprisingly, two articles on snowflake anomalies have appeared recently. To form at all above -40 F, snowflakes supposedly require a solid seed or nucleus around which ice can crystallize -- or so scientists have assumed for many years. It was long believed that airborne dust, perhaps augmented by extraterrestrial micrometeoroids, served as the necessary nuclei. But cloud studies prove that there are about a thousand times more ice crystals than dust nuclei. Now, some are convinced that bacteria blown off plants and flung into the air by ocean waves are the true nuclei of atmospheric ice crystals. Remember this the next time you tast a handful of snow!

Studies of these rings have led some astronomers to wonder if they are really as old as Saturn itself. Two lines of thinking suggest a recent origin: (1 ) The rings are composed of both light material (very likely water ice) and dark material (probably rocks and dust). The rocky fragments, according to the prevailing nebular theory, should have condensed early in solar-system history, and then been swept gravitationally into the planet as they were slowed by friction with the uncondensed nebular material. Yet, dark material is still in the rings. (2 ) The incessant bombardment of the rings by meteorites should have pulverized the rings, sending fragments and vaporized material in all directions. In just 10 million years the rings should have been largely erased. They are still there. (Cuzzi, Jeffrey N.; "Ringed Planets: Still Mysterious -- II," Sky and Telescope, 69:19, 1985.) Comment.

Three "sludgy" sites have been high-lighted in the recent literature. (1 ) Comets. "Black" comets certainly defy our expectations. Are all those pictures of white, flaming apparitions wrong? Not really. The comets approaching the sun are made visible by sunlight reflected from the gases and dust in the coma and tail, plus some direct emission. However, the heart of the comet, its nucleus, has long been considered a "dirty snowball"; that is, a mixture of dirt and ices. Now it appears that comets are more like "icy dirtballs"!

Leave comfortable earth for a moment and consider the immense, cold clouds of gas and dust swirling between the stars and galaxies. At near-absolute-zero, sunless and waterless, these clouds hardly seem the womb of life. Yet, there may be found the atoms necessary to life -- H, C, O, N, etc -- and in profusion. Collisions of cosmic rays can promote the synthesis of fairly large molecules. We have already detected molecules as complex as formaldehyde in the interstellar medium. But surely the immensely more complicated molecules of biology cannot be synthesized near absolute zero. This may not be true either because at extremely low temperatures the quantum mechanical phenomenon of "tunnelling" becomes important. To achieve molecular synthesis, repulsive barriers must be overcome. The warm temperatures in that terrestrial pond can provide the extra kinetic energy to climb over these barriers. In cold molecular clouds we must look elsewhere. The laws of quantum mechanics state that there is always a very low probability that atoms and molecules can tunnel through repulsive barriers -- no need to climb over them via thermal effects. "Specifically, entire atoms can tunnel through barriers represented by the repulsive forces of other atoms and form complex molecules even though the atoms do not have the energy required by classical chemistry to overcome ...

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.

Muller and D.E . Morris review the evidence tying geomagnetic reversals to the impacts of large bodies with the earth: the tektites and microtektites; the climate changes; the biological extinctions, etc. Then they propose a physical mechanism for geomagnetic reversals: "The impact of a large extraterrestrial object on the Earth can produce a geomagnetic reversal through the following mechanism: dust from the impact crater and soot from fires trigger a climate change and the beginning of a little ice age. The redistribution of water near the equator to ice at high latitudes alters the rotation rate of the crust and mantle of the Earth. If the sea-level change is sufficiently large ( 10 meters) and rapid (in a few hundred years), then the velocity shear in the liquid core disrupts the convective cells that drive the dynamo. The new convective cells that subsequently form distort and tangle the previous field, reducing the dipole component near to zero while increasing the energy in multipole components. Eventually a dipole is rebuilt by dynamo action, and the event is seen either as a geomagnetic reversal or as an excursion."

(Weisburd, S.; "Atmospheric Footprints of Icy Meteors," Science News, 128:391, 1985.) Comment. From this launchpad, one's thoughts can really take off. How much water can this bombardment of icy meteors add to the earth, Mars, and other solar system bodies? In the item under GEOLOGY about the Greenland ice cores, it was indicated that the extraterrestrial dust influx during the Ice Ages might have been as high as 3 x 107 tons per year. If 10,000 times this amount of water is added to the atmosphere from icy meteors, we are approaching 1012 tons of extraterrestrial water per year -- far from an inconsiderable amount. The effects on the earth's climate could be large. If even greater fluxes of icy meteors were intercepted in the past, one might account for "pluvial episodes" on the planets. And further, comets now seem to transport "primordial organic sludge" around the solar system, as mentioned earlier under ASTRONOMY. We will leave further speculation to the reader.

The terrestrial ages (times since arrival on earth) measure between 1,000 and 700,000 years, implying that the Antarctic ice sheet may be at least 700,000 years old.

Wind rather than water is now the main erosional force. The sand dunes and drifts, the wind-shadows behind rocks, and the sand-blasted surfaces all attest to the desertification of Mars. Ronald Greeley, of Arizona State University, and his colleagues have simulated Martian winds in a special wind tunnel at NASA's Ames Research Center. Using spacecraft-measured wind velocities and patterns, they tried to duplicate the Martian erosional environment. The results were a surprise. They implied that the Martian surface should be worn down by wind-driven sand and dust at rates up to 2 centimeters per century. But at that rate, the Martian craters, which are estimated to be hundreds of millions of years old, would have been worn level long ago.

... stars emplaced along the long axis of the elliptical galaxy. Some elliptical galaxies have up to twenty partial shells divided between the two ends of the ellipsoid. What is most intriguing is the fact that the shells are systematically arranged. The closest partial shell will be at one end of the ellipsoid, while the second closest will be at the opposite end. The third closest will be just beyond the first closest, and so on. The shells "interleave" or alternate ends as their distances increase. If the alternating partial shells of stars belong to the elliptical galaxy (they seem to, agewise), did the elliptical galaxy shoot the first wave out one end and then expel the second wave out the opposite end? Or did the alternating shells form in situ from the primordial gas and dust that made the galaxy? An-other possibility is that a small galaxy collided with the monster elliptical galaxy, and its constituent stars were scattered in regular waves. There is some physical and mathematical support for such a regular scattering of a burst of stars by a dense elliptical mass of target stars. (Edmunds, M.G .; "Galaxies in Collision," Nature, 311:10, 1984.) Comment. This star-scattering process reminds one of how electrons are scattered by crystals and other subatomic scattering situations. We may have here another place where quantum mechanics applies in macroscopic nature. Reference. Galactic "shells" are cataloged in AWO5 in our Stars, Galaxies, Cosmos. To order, visit: here .

... 40 m (centre to centre)." The other three sets are very similar and are omitted here. The aerial photo-graphs of the quintuplets are remarkable. Meteorologists describe the circles as being the consequence of a large central whirlwind accompanied by four satellites. There seems to be some aero-dynamic basis for accepting the reality of large vortexes attended by several smaller ones. (Meaden, G.T .; "Whirlwind Spirals in Cereal-Fields: The Quintuplet Formations of 1983," Journal of Meteorology, U.K ., 9:137, 1984.

Desert dust devils and steam devils often exhibit coordinated motion and geometrical organization. See GWW0 in Tornados, Dark Days, Anomalous Precipitation. This book is described here .

... forming sulphur gases into the troposphere and stratosphere. Although the ash gravitationally settles out within weeks, the aerosols spread around the globe and can remain suspended in the stratosphere for years. Because solar radiation is easily absorbed and backscattered by the volcanic particles, a haziness in the sky and a dimming of the Sun and Moon are produced. Very dense and widespread dry fogs occur, on the average, once every few centuries. The sizes and intensities of some of the largest of them before the modern scientific era have been estimated by several indirect methods. The densest and most persistent dry fog on record was observed in Europe and the Middle East during AD 536 and 537. Despite the earliness of the date, there is sufficient detailed information to estimate the optical depth and mass of this remarkable stratospheric dust cloud. The importance of this cloud resides in the fact that its mass and its climatic consequences appear to exceed those of any other volcanic cloud observed during the past three millenia. Although the volcano responsible remains a mystery, a tropical location (perhaps the volcano Rabaul on the island of New Britain, Papua, New Guinea) can be tentatively inferred." (Stothers, R.B .; "Mystery Cloud of AD 536," Nature, 307:344, 1984.) Comment. Some of the "dry fogs" were accompanied by luminous nights, as in 1821 and 1831.

... last issue of Science Frontiers. Now, in a recent issue of New Scientist, T. Hallam raises still more objections: Tropical plants, mammals, crocodiles, birds, and benthic invertebrates were little affected by whatever happened at the Cretaceous-Tertiary interface. Furthermore, many groups that were extinguished were already well into a decline. Some geologists insist that some of the supposedly synchronous extinctions were probably separated by several hundred thousand years; viz., plankton and dinosaurs. The vaunted iridium anomaly in deep-sea cores is spread through a considerable thickness of sediment. Even after allowing for the mixing of sediments, the iridium-rich layer is thousands of years thick. According to the asteroid scenario, the clay layer separating the Cretaceous from the Tertiary should represent the fallout from impact-raised dust, which would include asteroidal material and a mixed sample of earth rocks. However, in Denmark, the boundary is marked by the so-called Fish Clay, which is almost pure smectite -- a single mineral and not a mixture of terrestrial rock flour. If it wasn't an asteroid impact, why the iridium concentration? At least three hypotheses have been proposed to circumvent the asteroid debacle: (1 ) volcanic activity; (2 ) a concentration of micrometeorites, thousands of tons of which fall each day, through extreme reduction of sedimentation; and (3 ) selective enrichment of iridium by an anoxic environment acting upon kerogenand pyrite-rich clay. In short, some geologists at least do not find the asteroid hypothesis compelling at the moment. (Hallam, Tony; ...

... has strongly dominated Western thought since Descartes. The meanings or ideas imbedded in words which are spoken by one person and deeply accepted by another can be communicated to the cells of the body (and to chemicals within the cells); the cells then can change their activities in order to conform to the meanings or ideas which have been transmitted to them. The believed-in (suggested) idea of being stimulated by a poison ivy-type plant, transmitted to a person who is normally hypersensitive to this type of plant, can affect specific cells (probably in the immunological and vascular systems) so that they produce the same type of dermatitis which results when the person actually is stimulated by a poison ivy-type plant. Similarly, individuals who are viewed as allergic to pollen or house dust may not manifest the allergic reaction when they believe (falsely) that they have not been exposed to the allergic substance. .. .. . "Believed-in suggestions can affect specific parts of the body in very specific ways. Suggestions of being burned can give rise to a very specific irregular pattern of inflammation on the hand that closely follows the pattern of a previously experienced actual burn in the same place. Suggestions that a congenital skin disorder will ameliorate step by step first in one area of the body, then in another, can be actualized exactly as suggested. At least one set of investigators found that suggestions that specific warts will regress can be effective in removing just those warts and not others."
