Science Frontiers ONLINE No. 124: Jul-Aug 1999 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Offset Lunar Rainbow May 13, 1998. South Atlantic Ocean. Aboard the m.v . Appleby enroute from Long Beach to Port Talbot. "At 2225 UTC when a light rain shower was falling, a rainbow was seen on the starboard side roughly 2-3 cables from the vessel. It was very clear for about six minutes and was accompanied by a secondary bow after about half that time. The secondary one did not make a complete bow but seemed joined to the primary bow at its highest point, in a convergence area of deep blue, as indicated in the diagram. "The colours were very clear, with blues and purples visible in both parts. Both bows began to fade at about the same time as the moon once again passed behind another cloud." (Crofts, A.; "Lunar Rainbow," Marine Observer, 69:67, 1999.) Comments. Because moonlight is much weaker than sunlight, lunar rainbows are rather rare. Even so, they are not anomalous. It is the offset bow that is difficult-to-explain. Rainbow phenomena should be symmetrical around the line containing the light source (moon, here) and the bow itself. In GEB3 in Rare Halos, we note that no reasonable explanation exists for rainbows offset to one side. However, extra bows offset directly above the main bow can be explained as due to reflection of moonlight or sunlight off ...

... Science Frontiers ONLINE No. 129: MAY-JUN 2000 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects TLPs One Fades, Others Flash The TLP (Transient Lunar Phenomenon) reported in SF#127 involved a 40-minute darkening of an area near the lunar crater Aristarchus on April 23, 1994. 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. Sure ...

... Science Frontiers ONLINE No. 41: Sep-Oct 1985 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Galaxy Redshifts Come In Clumps "Red shifts in the light from distant galaxies seem to favor certain values, at intervals corresponding to a spacing of 72 kilometres per second, if the red shifts are interpreted as indicating the recession velocities of the galaxies. 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." Actually, Tifft has speculated that galaxy redshifts might represent an intrinsic property of galaxies, which takes on quantized values, like the energy states of an atom!

... Science Frontiers ONLINE No. 131: SEP-OCT 2000 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Planetary Conjunctions that Changed the World On May 17, 2000, five solar-system planets (Mercury, Venus, Mars, Jupiter, Saturn) plus the moon slowly wheeled into a tight 19 arc. 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 basic idea is that Heaven awards ruling power to a sage-king because of his virtue. His descendants remain as Earthly deputies until they become corrupted, whereupon outraged Heaven gives signs in the sky that the Mandate has passed on to a different sage-king to continue the cycle. Three transfers of the Heavenly Man-date marked the beginnings of the Hsu, Shang, and Chou Dynasties. In fact, the tightest grouping of the five visible planets in the period from 3, ...

... Science Frontiers ONLINE No. 132: NOV-DEC 2000 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Sandslides: Desert Catastrophes Some of the most important fossil discoveries being made today come from the desolate Gobi Desert -- a most unlikely place for the sudden mass burial of agile animals. Furthermore, the fossils now coming to light in the Gobi sandstones are not only abundant but also preserved with great fidelity. For example, at Ukhaa Tolgod, paleontologists are excavating the planet's largest assemblage of fossil vertebrates from the end of the Cretaceous Period (71-75 million years ago). In 1993, about 1,000 fossils representing 20 species of mammals and reptiles were collected. Amazingly, these bones were not disarticulated, scattered about, or severely worn. It was obvious that the Ukhaa Tolgod animals had been very suddenly engulfed by a "tidal wave" of sand. It was a catastrophic event of some sort. But what kind of catastrophes occur on desolate, riverless deserts? Wind is always blowing sand about and dunes creep along in deserts, but healthy animals easily avoid burial. Of course, there are rare, sudden downpours even on the Gobi. But one would expect this rain to be quickly absorbed by the sand. Intrigued by the evidence of unexpected catastrophism in the Gobi, scientists from the American Museum of Natural History first took a look at Nebraska's strange Sand Hills. These Sand Hills stretch for thousands of square miles, reach heights of 400 feet, and are believed to be of aeolian ...

Science Frontiers ONLINE No. 85: Jan-Feb 1993 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Electronic Channeling Those ubiquitous solar-powered calculators may be the latest mechanism by which other "intelligences" are trying to communicate with us. Here is how this novel information channel works. You put your solar-powered calculator (a cheap one will do) in your desk drawer and close it. When you again open the drawer and light hits the calculator, a number, perhaps a letter, or even an unrecognized symbol may appear. What's going on here? What do these "messages" mean? C. Bentley, in a letter to the New Scientist, related how his calculator most frequently flashes the number 5, but many other numbers may also appear. His calculator works perfectly after he has disposed of the gratuitous information. Something must be generating these strange data. In his final paragraph, Bentley muses: "It has occurred to me that perhaps someone or something is trying to communicate but I fear that if this is the case the message has so far eluded me. The numbers don't work on pools either." (Bentley, Chris; "Dark Secret," New Scientist, p. 52, October 10, 1992.) From Science Frontiers #85, JAN-FEB 1993 . 1993-2000 William R. Corliss ...
