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"! And some of that dirt is pitch black. New measurments of the bare nuclei of comets, using a visual-infrared technique, find that the nuclei reflect as little as 2% of the incident sunlight. They are indeed charcoal black. Comet nuclei, according to W. Hartmann and his colleagues, are colored by a brownishblack primordial organic sludge, and have the appearance of "a very dark Hershey bar." The use of the adjective "organic" may be premature, but in light of the next item, maybe not. (2 ) Carbonaceous chondrites .

Its claim to fame is a very short period of rotation -- only 685 seconds. In just a shade over 11 minutes, a neutron star orbits a white dwarf, according to present thinking. The orbit diameter is only 1/7 the radius of our sun, which implies the stars themselves are also small. 4U1820-30 is the shortest-period binary ever found -- so short that astronomers are looking for other explanations.

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. These appeared harmless enough, but stepping through the outer wall into the vortex sucked the air out of the lungs. "Outside our hangar there is a large stretch of wind-sheltered concrete which becomes intensely hot. In this area, close to the foot of the hangar, one can start up one's own little devils on occasions by a quick sweep of a signalling bat (which is shaped like a large ping-pong bat) from shoulder level in circular and downwards direction to a point almost touching the ground; one must step rapidly back or the vortex that is set up is spoilt.

R. Lynds, of Kitt Peak National Observatory, estimates that the arcs are as luminous as 100 billion suns. The nice circularity of the arcs is perplexing; and it is stated that nothing like them has been reported before. The arcs might be incandescent gas, but many astronomers opt instead for swaths of bright young stars. Spectroscopic tests will decide this point. It has been difficult to conceive of an origin for the arcs. Are they blast waves or the results of tidal action between galaxies? No one knows, for all suggestions seem flawed. Something out there not only manipulates stupendous amounts of mass and energy but also does it with a draftsman's compass.

According to the latest evidence, this provides a yardstick against which we can measure the absolute motion of the Sun through space. This rather startling indication that the red shifts of galaxies are quantised, rather like the atomic spectral lines by which the red shifts themselves are measured, has a pedigree that goes back more than 10 years. Since 1972, W.G . Tifft, of the University of Arizona, has been producing evidence for the red shift quantisation from analyses of various catalogues of galaxy red shifts and, as his collection of data has mounted, the idea, unpalatable though it seemed at first, has become steadily more respectable. It has not taken the astronomical world by storm, and even Tifft has no definite idea why the red shifts should be grouped like this. But it is no longer possible to dismiss the evidence out of hand."

Some of this loss is gradual and continuous -- the so-called stellar winds. Some is abrupt -- the sudden blowing off of a surface layer that then forms a shell around the star. A group of astronomers now reports in the Nov. 15 Astrophysical Journal the discovery of an especially large, cool shell around the star R Coronae Borealis. How this shell was formed and what makes it glow are both mysteries for which current theory does not seem to have answers." The newly discovered shell is 26 light-years across, roughly 20 times larger than previously discovered shells. If our sun were in the center, the shell would encompass the nearest 50 stars!

... Subjects Solar Neutrino Update Our terrestrial neutrino detectors catch only about 1/3 as many solar neutrinos as stellar theory requires. We frequently refer to this anomaly because at risk here is our basic theory of how stars work. Is our knowledge of stellar furnaces fundamentally in error or are some of the solar neutrinos somehow removed from the stream of neutrinos bound for earth? Recent calculations by Hans Bethe have brought sighs of relief to all astrophysicists. Without going into all of the details, Bethe finds that the interactions of the electron-neutrinos emitted by solar thermonuclear reactions with atoms constituting the solar mass change a substantial fraction of them into muonneutrinos. Since our terrestrial neutrino detectors register only electron-neutrinos, we may really be seeing only a fraction of the total number of neutrinos being emitted by the sun. If Bethe's calculations turn out to be correct, he may have eliminated a Class1 anomaly. But at a price! It seems that his calculations also predict a mass of only 0.008 electron-volts for the muon-neutrino. This is much too small for neutrinos to account for the "missing mass" of the universe -- something cosmologists had devoutly hoped for.

In recent years, however, a rival explanation has been found in the non-symmetric gravitational field of the sun. Surface oscillations of the sun betray hidden internal rotation, which produces asymmetry in the sun's gravitational field. By applying the distorted field in predicting the orbit of Mercury and the minor planet Icarus, astronomers are more successful than when they use the GR.

The overwhelming majority of the angular momentum is tied up in planetary motion. To make matters even more puzzling, the angular-momentum vectors of the sun and the planetary system are 7 apart.

Rapid condensation requires that the sun get a much bigger share of the angular momentum. These anomalies have led T. Gold to propose a slow-condensation model, in which several hundred million years are required rather than the tens of thousands of years in the current scenario.

It should, therefore, be getting brighter -- and it is -- but its brightness pulsates. A French team of scientists, led by Jean Lecacheux, has determined that Halley's Comet flares up at regular intervals just over 24 hours apart. We usually do not study comets carefully until they are very close to the sun, so we don't know if this blinking behavior is typical or not. The most reasonable explanation is that Halley's Comet rotates about every 24 hours and that its surface is not uniform. One portion of its surface may be brighter or emit more luminous gases than the rest. In any event, we have a new astronomical curiosity.

A century of various correlations has convinced almost no one. John P. Bagby has now introduced a new piece to the puzzle of solar-system cyclic behavior. While searching for possible perturbations of the planets due to a tenth major planet or a dark massive solar companion (MSC), he discovered that the perihelia of the outer planets (orbital points closest to the sun) were being disturbed with an average period of 11.2 years. This is almost exactly the sunspot period. This serendipitous finding caused Bagby to wonder whether some common influence was causing not only the sunspot cycle and those perturbations in outer-planet perihelia but also cyclic volcanic and seismic activity on earth. Some correlations indeed do indicate a sun-earth link of some sort. Bagby suggests two possibilities: (1 ) Mutual resonance effects between the planets, (2 ) The effects of a massive solar companion. (Bagby, John P.; "New Support for the Planetary Theory of Sunspots," privately circulated paper, 1983.) Comment.

Perhaps the Big Bang is just a facade that diverts us from theories that better explain the observed characteristics of the universe. A trio of American and British astron omers (B .J . Carr, J.R . Bond, W.D . Arnett) are exploring the possibility that the cosmos began with a generation of very massive stars rather than the debris of the Big Bang. These huge stars would have had masses 100 or so times that of the sun. By virtue of the much higher pressures and temperatures at their cores, they would have burnt up their fuel inventories much faster than sun-sized stars. Thus they would have burnt themselves out long ago, probably surviving as black holes. Such an ancient generation of massive stars can explain four puzzling features of the universe: (1 ) The amount and character of the background microwave radiation. (2 ) The identity of the "missing mass" needed to hold the universe together (i .e ., the relict black holes). (3 ) The primordial abundance of helium. (4 ) The near-absence of heavy elements in the universe. Although the success of this hypothesis is far from total, it might help wean us away from the Big Bang. (Maddox, ...

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.

That the Maya were acute astronomers is beyond question. They had even developed a correction scheme to keep Venus' 584-day canonical cycle on track with its true synodic period of 583.92 days. Their predictions of the position of Venus were accurate to 2 hours in 481 years! Not bad for a civilization that did not seem to have any conception that the planets revolved around the sun. The Maya, in fact, did not seem to care what made heavenly bodies move; they only wished to predict their appearance accurately. Instead of developing celestial mechanics based on gravitation and laws of motion, as we have done, they were content with numerical algorithms; that is, ways of computing a desired result. Their astonishingly accurate predictions of Venus, solar eclipses, and other astronomical phenomena evolved from cycles of numbers advancing each day like interlocking gear teeth. These algorithms gave them no insight into cause and effect, but they got the right answers. They needed no physical laws, just patterns of numbers.

But it is not the mindboggling number of stars that is anomalous (astronomy dotes on big numbers); rather the anomaly at hand concerns the 11% of the elliptical galaxies that are partly girdled by strange low-luminosity shells. First reported in 1980, these sharply defined shells seem to be composed of still more stars -- vast ellipsoidal sheets of 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?

The motion of Antarctica's ice sheet carries these meteorites conveyor-belt fashion out towards the encircling seas. But where Antarctic mountains get in the way, the rocky cargo tends to get concentrated. Several thousand meteorites have already been picked up at these favored spots. In just a few brief summers of searching, these massive finds have posed unexpected questions. Here is a sampling. 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.

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. (Anonymous; "New Light on Novaya Zemlya Polar Mirage," Physics Today, 34: 21, January 1981.) Reference. Related atmospheric phenomena are collected in Section GEM in our Catalog: Rare Halos.

Science Frontiers ONLINE No. 22: Jul-Aug 1982 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects How can the sun influence chemical reaction rates?When water is added to bismuth trichloride, a precipitate, bismuth oxychloride, forms. The precipitation rate seems to vary with time, being different from one month to the next. This time variation has been confirmed at many laboratories around the world and is not dependent on any obvious meteorological condition. Instead, some investigators claim to have found a rather good correlation with the sunspot cycle! (Majorino, Gianfranco, and Zecca, Luigi; "Period Analysis of the Picardi P-Test," Cycles, 33:78, 1982.) Comment. This precipitation test, called the Piccardi P-Test, has been offered for years by cycle students as proof of extraterrestrial influences on earthly chemistry, including biochemistry. No explanation has been suggested; and one reads about it only in "fringe" publications. From Science Frontiers #22, JUL-AUG 1982 . 1982-2000 William R. Corliss ...
