The phenomenon was observed independently by some 100 amateur astronomers. The initial analysis of data returned at the same time by the lunar satellite Clementine at first seemed to confirm the amateurs' telescopic impressions. But after correcting the satellite data for lighting geometry and other effects, Clementine's vision of the TLP faded away like the Cheshire Cat. TLP doubters were well-satisfied. (Anonymous; "Lunar Surface Change: A False Alarm," Sky & Telescope, 99:22, March 2000. Cr. D. Barbiero.) Comment. Were the independent observations by 100-or-so geographically dispersed amateurs all hallucinations? The TLP "myth" does not fade away so easily. On the night of November 17/18, 1999, the Leonid meteors pelted the earth's atmosphere and, as one would expect, the moon's surface. The moon's atmosphere, however, is almost non-existent so its share of the Leonid shower did not burn up before hitting the surface. But might not the high-velocity impacts with the surface create luminous phenomena? To find out, a team of observers monitored the dark side of the moon during the peak of the Leonid shower.

Recent studies of the Puerto Princesa seiches show that the amplitudes of the seiches are greatest every two weeks, indicating they are tied to the astronomical tides. However, they lag the lunar tide by a couple of days. Geophysicists now look to Pearl Bank in the Sulu Sea, some 450 kilometers southeast of Puerto Princesa, where they believe tidal currents create "internal waves" as they hit the shallow bank. These internal waves travel beneath the surface at speeds of only about 8 kilometers/hour, taking about 2 days to reach Puerto Princesa.

Burr was inserting electrodes into trees to measure how voltage differences varied during the day and lunar month. Y. Miwa, at Waseda University in Tokyo, has gone more than one step farther. He and his coworkers have placed electrodes in the trunks of trees - 250 trees at a time - and measured the voltage differences every 2 seconds. They have discerned intriguing synchrony. "Miwa and his colleages studied primeval forests in Japan's Shizuoka and Nigata Prefectures, recording signals for two days at a time. In each forest, there were several groups of between 20 and 50 trees showing a similar pattern of changes in their potentials, each of which contained about half a dozen species. Neighboring trees were the most likely to be synchronized, but the groups did not have rigid boundaries. The membership of the groups was also not fixed: between the first and second days of recording, individual trees 'joined' and 'dropped out'." Miwa advances the idea that the trees must somehow be communicating with each other to achieve this synchrony. Botanists, though, suspect that environmental conditions force this coordinated behavior. Miwa will next remove a few members from each group to see if his arbicides are noticed by the neighbors.

After examination and measurement, the patterns of its carefully inscribed markings are believed to be identifiable as a calendar fashioned for use at Stonehenge.

The sunspot cycle can be seen in variations of varves; i.e ., annual layers of sediment; and the growth rings of shells have been used to estimate the number of days in the lunar month when the solar system was younger. Cyclothems may also be useful. Cyclothems are groups or bundles of strata that repeat themselves in stratigraphic columns. A generalized cyclothem from Illinois is shown in the illustration. In the U.S . western interior, rhythmic sedimentation appears in the Fort Hays Limestone Member of the Niobrara Formation. These cyclothems can be correlated over distances exceeding 800 kilometers and are believed to be the consequence of climatic changes associated with the earth's precession and orbital eccentriciy. These rhythms have been captured in bundles of shale-limestone couplets. A bundle of five coup lets, for example, is thought to express 21,000- and 100,000-year Milankovitchtype climatic cycles, as impressed by variations in the earth's orbital precession and eccentricity.

Pearson. He ventures that our ponderous moon (much larger than the moons of Mars) was the key to the melting of the earth's core via tidal friction. With a fluid core, the earth developed a strong magnetic field (much stronger than those of the other inner planets) through dynamo action. This field protected nascent life from space radiation -- and here we are! (Hecht, Jeff; "Lunar Link with Life on Planets," New Scientist, p. 40, January 21, 1988.) Comment. Current scientific opinion declares that the moon was captured by the earth -- a rather rare astronomical event. The capture of a very large moon would be even rarer. From this shaky chain of thoughts, we conclude that life in the universe must be exceedingly scarce. However, such long chains of inferences are usually found to be far off the mark.

The only viable alternative is origin by lunar volcanism, which implies the following: continuance of (rare) explosive lunar volcanism to the present time; existence of silicic lunar volcanism and of small patches of silicic rock at the lunar surface; a body of rock in the lunar interior, probably at great depth, which is closely similar to the earth's mantle and which contains billions of tons of volatiles, probably including hydrogen; and the origin of the moon from the earth after the formation of the earth's core."

(Here, "fresh" means post-mare formation.) Such an origin would seem to favor random distribution of these craters. "However, it appears that the distribution of these large, fresh craters is far from random, contrary to what would be expected if their mechanism of formation was by impact. Even the most casual observer of the Moon cannot help but note that the maria contain very few large craters. The more experienced observer will take note of several apparent anomalies. Six magnificent post-mare craters are almost fortuitously located immediately adjacent to mare regions, these being Langrenus, Theophilus, Cavelerius, Aristoteles, Aristarchus, and Copernicus" The author of these observations then buttresses them with a statistical analysis, which indicates a strong, nonrandom distribution of all of these fresh craters. Apparently, the volcano-meteorite controversy is not completely settled after all these years. (Kitt, Michael T,; "Anomalous Distribution of Large, Fresh Lunar Craters," Strolling Astronomer, 31:22, 1985.) Comment.

The clear favorite among the four contending hypotheses was the earth-impact scenario, which may be stated as follows: "Near the end of the Earth's accretion, after its core had formed and while the growing planet was still molten, an object at least the size of Mars smashed into it at an oblique angle. The cataclysm put large quantities of vaporized or partially vaporized impactor and Earth into orbit. The primitive Moon formed from that material." Conferees turned thumbs down on the theory that the moon was captured by the earth. Still not ruled out are the double-planet hypothesis (earth and moon accreted in their present configuration) and the fission-from-earth theory. (Taylor, G.

Yet, there is no agreement as to its mode of origin. One might say that planetary scientists have just about thrown in the towel on the three major theories of lunar origin. Two recent articles attest to this discouraging situation. A Sky and Telescope article provides an excellent review of all three theories, indicating the reasons why each fails to convince a majority of scientists. The theories and the primary reasons for their rejection are: (1 ) Fission from earth . Lack of sufficient angular momentum in the earthmoon system and the fact that the moon does not orbit in the plane of the earth's equator. (2 ) Gravitational capture . The capture of such a large object in a nearly circular orbit is considered too improbable. (3 ) Earth-moon accretion as a double planet . The compositions of the earth and moon are too different. This article concludes that the resolution of the problem of lunar origin must await our return to the moon for more scientific exploration. (Rubin, Alan E.; "Whence Came the Moon?"

They are found primarily in four strew fields in Europe, Australia, North America, and Africa. Just about everyone believes that tektites are once-liquid droplets of rock that were solidified in flight. The major question -- often intemperately debated -- is the location of the tektite source. Are they of terrestrial, lunar, cometary, or some other origin? A recent study by Shaw and Wasserberg, using element abundances as a guide, strongly favors a terrestrial origin, with meteor impacts serving as the liquefying and splashing agents. Indeed, specific craters have long been associated with the European and African strew fields. Those who believe that the tektites were splashed all the way from the moon by meteor impacts have not given up yet. One provocative fact stressed in this article is that the ages of the four groups of tektites are 35, 14, 1.3 , and 0.7 million years. Tektites are all quite young! (Smith, Peter J.; "The Origin of Tektites -- Settled at Last?" Nature, 300: 217, 1982.) Comment. Were there no tektite-forming meteor impacts prior to 35 millions of years ago?

First, the meteorite's isotope ratios echo those found in bona fide moon rocks. Second, the meteorite is a breccia, consisting of small chunks cemented together, some of which are pinkish, magnesium-aluminum-rich spinels sometimes seen in lunar rocks but not terrestrial rocks or ordinary meteorites. Anorthosite is also present -- a type of rock found on the earth and moon but not ordinary meteorites. The implication is that ALHA 81005 was blasted off the moon by a comet or big meteorite. It escaped the moon's gravitational field, was captured by the earth, and plunged into the Antarctic snows. (Eberhart, J.; "Early Hints at a Moonish Meteorite," Science News, 123:54, 1983.) Comment.

Sure enough, the moon-modulated matings of these worms seem to improve reproductive efficiency. Less well known are many other moon-synchronous biological rhythms; viz., the sizes of the pits dug by ant lions to trap ants and the angles flatworms assume in swimming away from light. Many such lunar rhythms apparently have no adaptive value whatsoever. So, why do they exist? Even more disconcerting is the fact that lunar rhythms persist in the lab where the moon is not visible.

They were startled to discover thousands of elliptical craters or pockmarks in the sediments. The craters are 30-330 feet across, 6-25 feet deep, and located in water about 500 feet deep. The long axes of the craters point roughly in the same direction; and the craters tend to be arranged in lines. The authors suggest that escaping subsurface gases and fluids may have formed the unusual structures. The possibility was underscored on July 30, 1978, when a very large eruption of sediment was detected by sonar.
