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. 73: Jan-Feb 1991 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Saturn's latest burp In late September, 1990, a large white spot appeared on Saturn. Soon, this blemish spread into an oval 21,000 kilometers in length. By early November, it had developed into a planet-encircling band. Apparently, Saturn had "burped," expelling hot gases from its interior. [Saturn emits 50% more heat than it absorbs from the sun.] So far, this is not too beguiling to the anomalist. But now it seems that other white spots, not as large, have been recorded in 1876, 1903, 1933, and 1960. Could the white-spot phenomenon be periodic--like a percolator? More food for thought is found in Saturn's orbital period around the sun: 29.4 years -- not too different from the potential "burp" cycle!

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).

This anomaly leads to the outrageous possibility that Saturn is actually very young and has not cooled off as much as we would expect from theory. The infrared detector on the recent Voyager-1 flyby seems to show that the atmosphere of Saturn possesses only about half as much helium as theory would have. The surmise is that the missing helium is still residing in the planet. This might account for some of the abnormal heat generation. (Anonymous; "Puzzling over Saturn's Internal Heat," Eos, 62:538, 1981.) Comment. Thus, the excess-heat anomaly may be replaced by the missing-helium anomaly. Curiously, some ancient myths refer to Saturn as the "sun of night." Could Saturn have been much brighter not too long ago? From Science Frontiers #17, Fall 1981 . 1981-2000 William R. Corliss ...

Science Frontiers ONLINE No. 60: Nov-Dec 1988 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Why didn't galileo resolve saturn's rings?Several times in SF and our catalogs, we have intimated that Saturn's rings may be of recent vintage or perhaps have changed in historical times. In this vein, K. Fabian writes about an interesting inconsistency: "In the early 17th Century, Galileo discovered that the planet Mars goes through a minor gibbous phase. Even in its maximum gibbous phase, Mars is 88% illuminated. Quoting James Muirden in the Amateur Astronomer's Handbook, 'It is remarkable that Galileo was able to make out the phase with his tiny telescope.' "Even more amazing, in my opinion, is that Galileo, while he was able to resolve the slight phase of Mars, was unable to resolve the major ring around Saturn. Mars is a difficult object in a small telescope, while Saturn is easily resolved as a ringed planet in even a 40-mm spotting scope at 30X. Why did the rings of Saturn elude Galileo, while the more difficult Martian phases did not? Perhaps at the time of Galileo the rings of Saturn were much more difficult to observe than they are today." (Fabian, Karl; personal communication, September 9, 1988.) Reference.

Science Frontiers ONLINE No. 39: May-Jun 1985 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Saturn's rings may be young When the Voyager spacecraft swept past Saturn, they radioed back photos of a complex, very dynamic system of rings -- thousands of rings. 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. Assuming the rings are young, where did they come from? What happened to Saturn in "recent" times? Reference. Several lines of evidence point to the youth of Saturn's rings.

New termed SEDs (Saturn Electrostatic Discharges), the period of these bursts would be matched by the period of an object rotating around Saturn at a distance of about 100,000 kilometers. Is there anything visible at this distance? Sure enough, Voyager optical instrumentation detected a thinning, possibly an actual gap, about 150 meters wide, in the B-ring at this radius. The big puzzle is why a thinness or gap is maintained over a long period of time and how it is associated with the SEDs. (Evans, D.R ., et al; "The Source of Saturn Electrostatic Discharges," Nature, 299:236, 1982.) Comment.

These dark areas seem to rotate with the rings and are likely regions nearly devoid of the particles that constitute the rings. The "normal" annular gaps between the rings can be explained in part as due to the gravitational influences of Saturn's moons. The dark spokes, however, do not succumb so easily. There are no obvious gravitational nuances that can sweep particles selectively from radially aligned areas. (Anonymous; "Voyager Discovers Spokes in Saturn's Rings," New Scientist, 88: 276, 1980.) Comment. Any theory accounting for radial gaps may also explain the "knots" of brightness occasionally seen through the telescope down the years. Incidentally, a few observers in the past have also claimed to have seen radial gaps in the rings, so the dark spokes are not exactly new. Reference.

This is very close to the rotation period of Saturn's magnetic field. Somehow, the rotating magnetic field interacts with the particles making up the rings, forcing density or reflectivity changes that we see as transitory spokes. It is not yet clear how this magnetic tune is played. (Proco, C.C ., and Danielson, G.E .; "The Periodic Variation of Spokes in Saturn's Rings," Eos, 63:156, 1982.) Comment. Brightness changes have also been noted in the zodiacal light, which is light reflected from particles surrounding the sun. After reading about Saturn's variable spokes, one wonders whether solar-system magnetic fields might be the cause of these mysterious variations in the zodiacal light.

Phoebe is nicely rounded, 200 kilometers in diameter, and swings around Saturn in a retrograde orbit 550 days long -- nothing anomalous so far. Phoebe, however, turns out to be the only solar-system satellite whose axial period of rotation is not about equal to its period of rotation about its parent planet. All other moons, including our own, are gravitationally "locked" so that they always point the same hemisphere at the parent planet. (Anonymous; "Voyager's Fleeting Glimpse of Phoebe," New Scientist, 91:779, 1981.) Comment. One inference here is that Phoebe is a relatively recent addition -- and a good-sized one -- to the Saturn system, and just hasn't been there long enough to become "locked."

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."

The anomalies are so large that astronomers have concluded that these objects must have undergone considerable evolution after they were formed by accretion (the currently accepted mode of formation). Unfortunately these four satellites are so small that they could not have accommodated any reasonable energy source capable of causing the observed crustal evolution. The authors suggest strong local concentrations of radioactive heat generators rather than uniformly distributed radiogenic substances, such as those that helped mould the earth's surface.

Compared to the purported age of the solar system, 4.5 billion years, Saturn's C-ring (and perhaps the other rings, too) is a brand-new feature. Where did it come from? Is it related to the icy comets that seem to be raining down steadily on the earth's atmosphere?

Being so weighty they strongly perturb the orbits of comets, deflecting many away from the inner solar system, where we reside. Calculations by G. Wetherill, at the Carnegie Institution, reveal that if Jupiter and Saturn were only 15 times the mass of the earth, the earth would have been devastated every 100,000 years by giant comets, instead of about every 100,000,000 years, as indicated by the geological record. Under such intense bombardment, it would probably have been difficult for advanced life forms to develop. (Croswell, Ken; "Why Intelligent Life Needs Giant Planets," New Scientist, p. 18, October 24, 1992.) Comment. Reasonable as the foregoing assertion sounds, we do not really know what stimulates the development of new life forms. Actually, the fossil record reveals that some biological "radiations" occurred soon after great geological upheavals.

... 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. Neptune's rings may also be young. See SF#43 and ARL16 in our catalog: The Moon and the Planets. This volume is described here . ...

Hyperion's irregular shape and the gravitational pull of Titan, a larger satellite of Saturn, make it a prime candidate for chaotic motion. After accumulating 53 Hyperion-days of observation, J. Klavetter has confirmed this theoretical suspicion. Hyperion's brightness varies wildly from day to day, as it spins unpredictably. The laws of motion and the largest computers are helpless here; although computer simulation can identify situations where chaos might develop.

... publicity given to the 1984 observations of possible discontinuous rings around Neptune (SF#38) have brought to light two other enigmatic observations. The 1981 sighting of a "third satellite" of Neptune have now been interpreted as still another discontinuous ring at a different radius. A third discontinuous ring seems to be indicated by the reanalysis of some 1968 occultation data. Astronomer Bill Hibbard, at the University of Arizona, speculates that the three separate arcs of material orbiting Neptune are "trying to decide whether to become a satellite." (Hecht, Jeff, and Henbest, Nigel; "Neptune's Arcs -- A Satellite in Formation?" New Scientist, p. 19, Apil 25, 1985.) Comment. If the debris around Neptune is just now accreting into satellites and Saturn's rings really do have youthful features (SF#39), one has to consider some disquieting possibilities: (1 ) Saturn and Neptune have been recently "disturbed," or (2 ) The entire solar system is not as old as the conventional scenario demands.

... anomaly for another day, the one we are after now is called: The Winding Dilemma. N. Comins and L. Marschall elaborate as follows: "Stars closer to the center of a spiral galaxy don't have as far to go to complete an orbit as stars located farther from the center. Thus, inner stars should orbit more frequently than outer stars, resulting in a spiral that gradually winds up as the galaxy ages. But observations of spiral galaxies at various distances -- and thus at different stages in their evolution -- have shown that this is not the case. Astronomers believe density waves, stochastic star formation, or perhaps a combination of both processes may sustain or regenerate the spiral pattern." Density waves have recently been applied to explain the spiral rings of Saturn, and now to the arms of spiral galaxies. The density waves are thought to stimulate the condensation of bright new stars as they move through space. A good analogy is the bioluminescent wake of ship in tropical waters. The density waves in a galaxy maintain the spiral pattern with new stars, while the old stars die out (in much less time than it takes for them to orbit the hub) as they orbit out of the spiral pattern. Postulating density waves just raises more questions, as is often the case in science. What causes the density waves? Theory says that the density waves should damp out in under a billion years, yet we see spiral galaxies over a wide range of ages. (Comins, Neil, and Marscall, Laurence; "How Do Spiral ...

These two giant planets can gravitationally deflect potentially devastating asteroids and comets away from the earth. It seems now that we are doubly lucky! Computer runs demonstrate that the presence of our large moon has stabilized the earth's spin axis down the eons. Presently, the earth's spin axis makes an angle of 23.5 with the plane of the earth's orbit (its "obliquity"). The well-known result is our yearly procession of seasons. Without the steadying effect of the moon, however, the earth's obliquity would probably have swung chaotically over much larger values. Such extreme changes would have been inimical to the development of life, particularly advanced life. As a case in point, the polar axis of Mars, with only two tiny moons to dampen its spin excursions, seems to have gone through many wild swings, as indicated in the figure.

It was a notable heavenly conjunction. All manner of natural catastrophes were predicted but failed to materialize. It has been this way down recorded history. Universal deluges were anticipated during similar conjunctions on September 14, 1186, and February 19, 1524, but the weather refused to cooperate with the planets. Humanity survived nicely. This does not mean that historical upheavals are never correlated with planetary conjunctions. If a society believes strongly enough in the power of the stars and planets to shape human destiny, events may be correlated with the heavens. Such was the case in ancient China. In China, the "Mandate of Heaven" concept has been used since ancient times as both a framework for history and a guide to future actions.

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. It should also be noted that modern astronomers have always laughed off the 1846-1847 observations of a Neptunian ring by W. Lassell and J. Challis!

This is roughly the size of the solar system inside Saturn's orbit. This tiny radio source is so energetic that there seems no escaping the conclusion that it is a blackhole. No other astronomical object is capable of generating so much energy in so small a volume. Since other galaxies also seem to harbor small, but very powerful radio sources in their centers, astronomers wouldn't be too surprised if all galaxies had black-hole cores. Quasars, in fact, might be galaxies with spectacularly active centers. Would these unseeable black holes be the notorious "missing mass" in the universe? Not likely. The mass of the purported black hole in our Galaxy is only about several million solar masses-- not even close to what is needed.

This tilt is embarrassing to the reigning "dynamo theory," in which the axes of the magnetic field and rotation are presumed to be aligned. The situation is even worse with some the other planets; viz., Uranus with 60 and Neptune with 47 . Jupiter's tilt is 10 , while Saturn's is only 1 . Clearly, something is awry. Two possibilities are: (1 ) The dynamo theory is incorrect; or (2 ) The magnetic fields measured by spacecraft are actually combinations of central, dynamocreated, dipole fields, which are aligned with the axes of rotation, and "other" dipole fields originating in the outermost portions of the planetary cores. If the latter solution to the dilemma is correct, we must account for the origin and disposition of these "other" dipoles.

A Soviet astrophysicist has made the startling claim that the Earth and other astronomical bodies may be riddled with mini black holes -- objects smaller than atoms but with masses which, in some cases, might be as great as a planet. Such objects, he claims, could account for volcanic hot spots, gravitational anomalies, concentrations of mass on the Moon (mascons), the existence of the rings of Saturn, and even the observations that gave rise to the notion of a 'fifth force.'" J. Gribbin, whose article begins with the above paragraph, is quick to proclaim that this "theory of everything" is not just silly-season kite flying. Rather, it was proposed by A.P . Trofimenko in the well-respected Astrophysics and Space Science (168:277) Restricting ourselves to speculations concerning the earth, Trofimenko sees our planet as a sphere of low-density material enclosing 126 mini black holes that account, first, for the many gravity anomalies we measure on the surface; and, second, the earth's high density. That's right, there's no iron core in this model! Some of the mini black holes near the surface create local hot spots (plumes, volcanos, etc.) through the emission of Hawking radiation.

In the past, the Earth had a ring system just like Saturn, Uranus and Neptune, according to a Danish astronomer. He has gone so far as to say that our planet boasted rings on 16 separate occasions in the past 2800 years. "Kaare Rasmussen of the National Museum in Copenhagen carried out a survey of all reports of meteorite falls, fireballs and showers of shooting stars from 800 BC to 1750 AD. He then carried out a statistical analysis of the data. He discovered that there were many distinct periods of intense activity." Rasmussen found that the active periods, during which he believes a ring existed about the earth, began with a peak of high meteoritic activity as the ring formed, as a consequence of the earth's capture of a comet or asteroid. This was typically followed by a decrease of activity indicating ring stability. Finally, the ring broke up as its particles were decelerated by the earth's upper atmosphere, leading to another peak of activity. Thus, the plot of me-teorite activity is U-shaped, as in the figure, with the bottom of the U a bit higher than the normal background. (Gribbin, John; "Will the Earth's Rings Return?"

The sudden change in the abundance of forest plants suggests that the winters became much more severe while the summers remained about the same. At about the same time, the radiolaria were devastated by some sort of disaster. This was also the time when the North American tektite strewn field was deposited -- a field that stretches halfway around the world. John O'Keefe hypothesizes that some of the tektites and microtektites that rained down during this period missed the earth and went into orbit around it, forming an opaque Saturn-like ring. This ring might have lasted a million years or more; and its shadow could have caused the extrasevere winters postulated from botanical data. (O 'Keefe, John A.; "The Terminal Eocene Event; Formation of a Ring System around the Earth," Nature, 285:309, 1980.) Comment.

... Project Sourcebook Subjects Cosmic Death Waves In the language of science, W.M . Napier and S.V .M Clube provide a scenario of cyclic terrestrial catastrophism. 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.

However, I do not know that the effect is not there; my skepticism cannot be considered closed-mindedness, any more than a gullible acceptance of astrology should be regarded as openmindedness. If the planetary effects suggested by Gauquelin are real, then his discovery is of profound importance. Consequently, I think the Gauquelin evidence, based on a great mass of data collected over many years, deserves to be checked out." While Gauquelin has concentrated on sports champions, he has found similar effects for other vocations. Musicians, for example, have a negative Mars Effect. (Obviously, violinists should not compete in the broad jump!) Scientists are positive with Saturn; actors are positive with Jupiter. And so on. (Gauquelin, Michel; "Is There a Mars Effect?"

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. The theory doesn't say what happened to the debris from this colossal collision. As for Mercury's magnetic field, it is small, only 1% that of the earth. But where does it originate? All of the other planets with magnetic fields (earth, Jupiter, Saturn, Neptune, and Uranus) rotate rapidly and are believed to have molten interiors, allowing fluid dynamos to form. Mercury, in contrast, spins very slowly and seems solid throughout. Therefore, the magnetic dynamos that supposedly create the fields of other planets cannot exist inside Mercury.

Favorite theories lie in shambles; faces are very red; the most elite of our scientific institutions were caught with blinders on! Beyond these amusements, the practical import for energy production is enormous, and who know what else will eventuate? But what about science itself? First, cold fusion will doubtless generate a brand new crop of anomalies which we are only able to guess at now. Pertinent to our effort to catalog anomalies, it is possible that cold fusion may be occurring deep in the earth giving rise not only to heat but the upwelling flux of helium-3 , now called "primordial" perhaps in error. The icy planets Jupiter and Saturn generate heat, too, and may also be cold fusion reactors! Even the sun, which is undeniably hot (at least on the surface!), may be fusing light elements in ways we have yet to grasp in our stellar models. After all, no one has yet explained that deficit in solar neutrinos! There will be egg on a lot of faces if our notions of stellar energy generation are widly in error.

It was already sufficiently anomalous to discover that the planets possess fifty times the angular momentum of the much more massive sun. (See ABB3 in The Sun and Solar System Debris.) Astronomers have been attempting for years to explain this 50:1 split. Now, with the Oort Cloud apparently having ten times the angular momentum of the planets, the situation is much worse. According to Asimov, the solar-system angular momentum is split as follows: Oort Cloud 90% All of the planets 9.8 % The sun 0.2 % The total mass of the Oort Cloud is estimated to be roughly that of Saturn. The recent flyby of Halley's Comet created this dilemma. It was discovered that Halley was a chunk containing 140 cubic miles of ice - much larger than anticipated for this "typical" comet. If the estimated 2 trillion comets are, on the average, Halley's size, the Oort Cloud is a thousand times more massive than previously thought. This, combined with estimates of Oort Cloud distance and angular velocity leads to the almost ridiculous distribution of solar-system angular momentum tabulated above. This will keep the theorists busy for a while. (Asimov, Isaac; Frontiers: New Discoveries about Man and His Planet, Outer Space and the Universe , New York, 1989, p. 270. Cr. C. Ginenthal) Comment. Perhaps the Oort Cloud isn ...

... Science Frontiers ONLINE No. 58: Jul-Aug 1988 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Chaotic Dynamics In The Solar System The following abstract appeared in a 1988 issue of Eos, a weekly publication of the American Geophysical Union. "Newton's equations have chaotic solutions as well as regular solutions. The solar system is generally perceived as evolving with clockwork regularity, yet there are several physical situations in the solar system where chaotic solutions of Newton's equations play an important role. There are physical examples of both chaotic rotation and chaotic orbital evolution. "Saturn's satellite Hyperion is currently tumbling chaotically, its rotation and spin axis orientation undergo significant irregular variations on a time scale of only a couple of orbit periods. Many other satellites in the solar system have had chaotic rotations in the past. It is not possible to tidally evolve into a synchronous rotation without passing through a chaotic zone. For irregularly shaped satellites this chaotic zone is attitude-unstable and chaotic tumbling ensues. This episode of chaotic tumbling probably lasts on the order of the tidal despinning timescale. For example, the Martian satellites Phobos and Deimos tumbled before they were captured into synchronous rotation for a time interval on the order of 10 million years and 100 million years, respectively. This episode of chaotic tumbling could have had a significant effect on the orbital histories of these satellites." Theis abstract continues, naming as other candidates for chaotic histories: some of the asteroids, Miranda (a satellite of Uranus), and the planet Pluto. ...

... ?Nereid, a satellite of Neptune, is peculiar in several ways: Its orbit is retrograde and highly elliptical (1 .4 x 9.7 million kilometers) Its brightness changes by a factor of four as it rotates Its diameter, according to M.W . and B.E . Schaefer (Nature, 333:436, 1988) is thought to be at least 660 kilometers. None of these facts taken alone is anomalous, but (2 ) and (3 ) taken together seem incompatible. If the large brightness changes are due to a highly irregular shape, Nereid's 660-kilometer size is too large, because astronomers agree that gravitational forces will sphericize all objects larger than 400 kilometers. On the other hand, if Nereid is two-faced, like Saturn's moon Iapetus (it's carbon-black on one side, light-colored on the other), astronomers are again faced with trying to explain how such a large solar-system object can acquire so much carbonaceous material on one side only. Also, Nereid's eccentric, retrograde orbit surely hints at a history of capture or orbit disruption. (Weisburd, S.; "Neptune's Nereid: Another Mysterious Moon," Science News, 133:374, 1988. Also: Veverka, J.; "Taking a Dim View of Nereid," Nature, 333:391, 1988.) From Science Frontiers #59, SEP-OCT 1988 . 1988-2000 William R. Corliss ...
