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.

The Tunguska object left no smoky trail like many fireballs, but rather irridescent bands that looked like a rainbow. Following the "explosion," at least part of the object continued on in the same direction but veered upwards. [Meteors sometimes skip out of the atmosphere on trajectories like this.] Although the Tunguska event occurred on June 30, 1908, optical anomalies appeared all across northern Europe as early as June 23. These included mesospheric, silvery clouds, very bright nights, colorful twilight afterglows [something like those following the Krakatoa eruption], and remarkably intense and long-lasting solar halos. Some of these effects persisted until late July. Neither craters nor meteoric debris have been discovered so far, despite assiduous searches. The explosion created a shock wave that leveled 2150 km2 of taiga and a flash that singed about 200 km2.

In that incident, which occurred November 22, 1996, near the HondurasGuatemala border, there was also a detonation. "On the early morning of 1994 January 18, a very bright luminous object crossed the sky of Santiago de Compostela, Spain. From visual sightings, it is concluded that the object wasn't a meteoric fireball (bolide). A surface "crater" in Cando (close to Santiago) with dimensions 29 x 13 m and 1.5 m deep was later discovered within 1 km of the projected "impact" point of the luminous object. At this site, in addition to the topsoil, full-grown pine trees greater than 20 m high were thrown downhill over a nearby road, leaving the downslope edge of the "crater" untouched and with a steep interior wall (this would not be the case if a regular landslide were responsible for the transport). Standing trees below the "crater" showed embedded soil and plant residues up to heights greater than 3 m. No strange materials (meteorites or artifacts) were recovered in or close to the "crater"; all materials belonged to the site and were not shocked; thus an impact is very improbable.

Hundreds of such observations have accumulated since the Middle Ages. Modern more-systematic scrutiny indeed confirms that the moon is not such a dead place after all. (See ALF in The Moon and the Planets for much more on this fascinating subject.) Moonquakes, gaseous emissions, and even volcanic activity have been the favorite explanations of these TLPs (Transient Lunar Phenomena), but these are only surmises. The many close-up photos of the lunar surface taken in ... by the lunar satellite Clementine gave B. Buratti, K. Herkenhoff, and T. McConnochie the opportunity to search for geological common denominators connecting the sites where TLPs have been most frequent. The suspicious sites are characterized by bluish spectra that usually indicate unusually fresh deposits of lunar debris. Furthermore, these areas are usually found along the inside edges of large craters. Buratti et al opine that these are the sites of recent landslides that have cascaded off the crater edges. The dust and volatile gases released by these events might account for the observed luminous phenomena. (Cowen, Ron; "Explaining a Lunar Mystery," Science News, 150:314, 1996.) Reference.

Science Frontiers ONLINE No. 115: Jan-Feb 1998 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Tektite Mysteries Tektites are small glassy bodies found strewn on and near the surface in several regions of the world. They come in various shapes: droplets, buttons, even dumbbells. By general agreement, tekites are attributed to meteoric or cometary impacts that melt terrestrial rocks and splash liquid droplets into the atmosphere. There they are shaped by aerodynamic forces and solidify. This scenario is all very reasonable, but some nagging problems remain. Where-o -where is that crater? 770,000 years ago, a huge meteor hit somewhere on earth and strewed an immense batch of tektites and microtektites over fully 10% of our planet's surface (about 5 x 107 square kilometers). This is called the "Australasian strewn field." Such a recent cataclysm must have left a large and inescapable crater somewhere. The problem is that no one has yet found it. (Ref. 1) Many lines of evidence suggest that the missing crater is in Indochina. C.C . Schnetzler and J.F . McHone located four likely structures in Laos from Landsat images. However, visits to these areas found no evidence of an impact. (Ref. 2) So, this mystery persists. How were the Muong Nong tektites formed? Muong Nong tektites are unusually large (up to 24 kilograms), layered tektites. They are found in an area 1,000 kilometers in extent from Hainan Island to southern Indochina ...

... Subjects An exploded planet and the "face on mars"Between Mars and Jupiter swirls the main main asteroid belt. In the view of many astronomers, including T. Van Flandern, there resides the debris of an exploded planet. Van Flandern has adduced considerable evidence supporting the exploded planet hypothesis, which we will pass over in favor of a look at the possible effects of said exploding planet upon a large but equally hypothetical satellite of said planet. Such a satellite would have been heavily pelted by debris on the side facing the exploding planet. Furthermore, this battered sphere, having lost its gravitational "anchor," would assume a new orbit around the sun as well as a new orientation in space. Is there any object in the solar system plastered mainly on one side with debris and craters? You guessed it: Mars! What possible connection could there be between this purported cataclysm and the "face on Mars"? The connecting thread is very weak but so beguiling that we must mention it. T. Van Flandern has proposed eight tests for the artificiality of the "face" and its associated "pyramids," "city," etc. One is the three-dimensionality of the "face." Another is the "fractal" test, which is useful in distinguishing between artificiality and naturalness. The "face" readily passes four of the eight tests. A fifth test (bilateral symmetry) cannot be decided until we get more pictures. But failure looms on the last three tests (location, orientation, cultural purpose), unless Mars is sent back ...

We now have information from the Mars Global Surveyor (MGS), now orbitting the red planet, that the low-lying northern plains are much flatter than thought. For thousands of kilometers, they are smooth on a scale of hundreds of meters. This is flatter than the lava flows of the lunar maria; flatter than the smoothest central Sahara. These startling data come from the MGS's laser altimeter that can measure elevation of the terrain below it with 10meter accuracy averaged over the beam width of 150 meters. The only known terrain in the entire solar system that can match this flatness is the abyssal, sediment-filled floor of the South Atlantic. Hmmm! Does this imply that ...

The latter is definitely real and consists of an immense, low-lying plain centered roughly on the planet's North Pole. The opposite face of Mars is occupied by rough, cratered highlands. This sharp, profound crustal dichotomy has been known for many years and has resisted explanation. In SF#113, T. Van Flandern advanced the theory that the rugged southern highlands are composed of the debris from an exploded planet which Mars once attended as a satellite. Be that as it may, there is something puzzling about the northern plains. We now have information from the ...

(SFs #93, #102, #103, #110, to name a few) Here is another. December 9, 1997, Greenland. At 5:11 A.M ., crews of three trawlers at widely separated sites off south Greenland reported "a blazing fireball that turned night into day." At a distance of 100 kilometers (62 miles), the flash was compared to that from an atmospheric nuclear explosion. Danish officials dismissed the possibility of a surreptitious nuclear test. The U.S . Air Force stated that the object was neither a reentering spacecraft nor artificial space debris. Some seismic tremors also emanated from Greenland, so the impact of a large meteorite is suspected. Based on the visual sightings and a moving object caught on a parkinglot surveillance camera in Nuuk, Greenland's capital, the probable impact point is at 61 25' N., 44 26' W. Efforts to locate the meteorite will have to wait for favorable weather. The supposed meteor was not a small object. The Niels Bohr Institute in Copenhagen compared it to the Kap York meteor that fell south of Thule, Greenland, in prehistoric times. Pieces of this iron meteorite aggregating 50 tons have been collected. (Sawyer, Kathy; "Fireball a Mystery till Thaw," Charlotte Observer, December ...

But, methane burps are bizarre, and the properties of methane hydrate are so unfamiliar to most scientists and investigators of aircraft disasters that Spalding's idea has received scant attention.

From this information, one would bet heavily that this was simply a routine meteor detonation caused by the heat generated during entry into the atmosphere. The next morning, however, people discovered a landslide covering several acres on the slopes of Cerro Negro, a mountain 14 kilometers from San Luis. Did the meteor slam into the mountain overnight? So far, investigators have not been able to decide whether the landslide is just gravity-slumping on the slope or a disturbance created by the night's meteor.

... Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Broadside Against Small Icy Comets In a late-1997 issue, Geophysical Research Letters published a group of five papers that detailed five different lines of evidence that are inconsistent with the claim by L.A . Frank and J.B . Sigwarth that the earth is bombarded daily by 30,000 house-size icy comets. If such bombardment has really been occurring, scientists would have to rethink the origins of the earth's oceans, terrestrial life, and the formation of the solar system. No wonder the icy-comet hypothesis is strongly challenged! Three of the more interesting points made by this group of papers are as follows: Our moon could not escape the icy-comet bombardment. Roughly 1,000 craters 50 meters in diameter and splashes of debris 150 meters in diameter must occur each. There is no evidence that the moon is thus afflicted. Comets also carry the noble gases argon, krypton, and xenon. These gases should accumulate in the atmosphere as the comets disintegrate. The amounts of these gases actually measured are 10,000 times less than those the postulated bombardment would produce. The icy comets should break up near the earth and produce clouds of ice crystals. Sunlight reflected from such 30-ton clouds would be brighter than Venus and easily visible before they disperse. Such objects are rarely seen, implying that small icy comets do not exist in the numbers claimed. Preceding this series of five papers is one by Frank and Sigwarth in which they describe their detection of atomic oxygen ...

... half-century ago, Yale biologist H.S . Burr inserted electrodes into trees and found that the voltages between them varied with the phase of the moon. (Ref. 1) The influence of the moon upon trees is even more palpable: the diameters of tree stems also bloat and shrink with the position of the moon in the sky. There is a tide in the affairs of trees, it seems. If tides occur twice a day, so do the swellings and shrinkings of trees. These tidal patterns are evident even when the trees are kept in darkness and at constant pressure and humidity. Even more surprising, chunks of tree stems that are sealed to prevent water from flowing in or out will still expand and contract according to the 24-hour, 49-minute lunar cycle as long as the cambium, the most active growing region, survives. The dimensional changes are small -- only tenths of a millimeter, but even these seem too large, given the weakness of the moon's gravitational field here on earth. (Ref. 2 and 3) References 1.

Two now-discarded mechanisms of formation invoked: (1 ) immense schools of spawning fish; and (2 ) icebergs stranded as the Ice Ages waned. In presenting today's favorite theory, Floyd quotes from H. Savage's book The Mysterious Carolina Bays : "' These half-million shallow craters represent the visible scars of but a small fraction of the meteors that fell to earth...when a comet smashed into the atmosphere and exploded over the American Southeast,' Savage wrote. 'Countless thousands of its meteorites must have plunged into the sea beyond, leaving no trace; while other thousands fell into the floodplains of rivers and streams that soon erased their scars.'"

Enough high-resolution photos have been taken to prove that these grooves emanate from the large crater named Stickney and run around the satellite to its opposite side where they die out. This suggests that the origin of the crater and the grooves are related. Further, the widest and deepest grooves (700 meters wide and 90 meters deep) are located close to Stickney. On the other side of Phobos, grooves are consistently less than 100 meters wide. Despite these hints of impact origin, the grooves are not quite what one would expect from simple fracture by collision. Some show beaded or pitted structures. Other grooves are composed of irregularly bounded segments. Finally, some of the straight-walled sections seem to have slightly raised rims. Evidently, some internal forces, perhaps stimulated by the formation of Stickney, also played a part. (Thomas, P., et al; "Origin of the Grooves on Phobos," Nature, 273:282, 1978.) Reference.

Science Frontiers ONLINE No. 7: June 1979 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects The Moon And Life There are so many examples of lunar rhythms in terrestrial life that we tend to assume that these phenomena are understood. Obviously, evolution "created" these rhythms to further the cause of each moon-tuned organism. Palmer and Goodenough recount the classic example of the lunar synchronism of the palolo worm and add the even-more-amazing tale of P. megalops, another marine worm. 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.

The swirls are sharply defined but do not appear to scour or otherwise disturb the terrains where they occur. Similar swirl patterns have been recognized on Mercury. Two intriguing characteristics of the lunar swirl patterns are: (1 ) They coincide with strong magnetic anomalies; and (2 ) They appear to be very young, being superimposed on top of essentially all lunar features ... all ages.

Magma welling up in the crater solidified creating the nucleus of the North American continent. It is quite possible that the other continents began their existences in this way -- meteor impact.

This cataclysmic event is also blamed (by some, at least) for the apparent sudden biological extinctions recorded on these pages of the fossil record. In this setting, the authors of this paper calculate the effects on the earth of a 10-kilometer-diameter object impacting at about 20/km/sec. Do the theoretical results jibe with the geological and paleontological data? Very definitely. Crater ejecta rich in extraterrestrial material would be blasted to an altitude of 10 km, where winds would insure global distribution. In terms of biological stress, the 10-km projectile would transfer 40-50% of its kinetic energy to the atmosphere, creating a heat pulse that could raise global temperatures 30 C (50 F) for several days. Many large animals might well succumb to such a temperature transient. In addition, the protective ozone layer might be blown away by shock waves and not reform for a decade.

However, studies of the grooves revealed at least three families of grooves of different ages, with members of each family located on parallel planes cutting right through the body of the satellite. Two recent papers have proposed radically different explanations. A. Horvath and E. Illes wonder whether Phobos might not be a layered structure, having once been part of a larger stratified body.

The effect is most noticeable when these planets are close to earth and dwindles as they swing around to the other side of the sun.

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.

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?"

... taken from Nature. More de-tails may be found in Paleobiology, 10: 121, 1984. Freshwater life was unaffected; In Montana and its vicinity, the last occurrence of dinosaurs was detectably below the crucial boundary; Transitional floras also exist below the boundary; Apparently extraterrestrial material exists below the boundary; The expected effects of eliminating atmospheric ozone are missing; The Cretaceous-Tertiary boundary is coincident with a very large marine regression, suggesting a nonextraterrestrial cause; Marsupials but not placentals were nearly eliminated, while most aboreal multituberculates (a type of vertebrate) and birds survived; The predicted cooling effects on the earth are absent; The predicted effects of acid rain cannot be found; and Assuming a marine impact, no turbidites can be found; assuming a land impact, no large terrestrial crater has been discovered.

... pebbles, he also provides some fascinating facts about the real ones. Genuine Azilian pebbles seem to have been carefully selected for size and shape. Most are oval or oblong and may be up to 8 centimeters long, 3 centimeters wide, and one centimeter thick. Over a thousand have been found around Europe. They have been considered primitive art, markers for prehistoric games, and possibly early forms of notation. Claude Couraude has analyzed the markings and concluded that particular combinations of signs recur frequently; the same for certain numbers of dots. There are 16 simple types of signs (dots and lines) but only 41 of the many possible combinations have been found. Evidence supports the existence of some sort of 'syntax.' Couraud speculates that some sort of cyclic notation is involved, perhaps lunar in nature, like some of the markings found on bones from the same general period.

... 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. This is unfortunate for several proposed scenarios of recent catastrophism, which envision an iceless Antarctica. At least 20 amino acids appear in the more than 40 carbonaceous chondrites picked up with sterile equipment. These meteorites are dated as 4.5 billion years old, or 1 billion years older than the earliest terrestrial life found in the rocks. These finds highlight the old question: Did meteorites seed life on earth? The much-publicized "lunar" meteorite, supposedly blasted out of the moon's crust by asteroid impact, thence falling to earth, shows little evidence of mechanical shock. If this meteorite, with a composition so similar to the Apollo samples is not from the moon, where did it come from?

Science Frontiers ONLINE No. 43: Jan-Feb 1986 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Anomalous distribution of large, fresh lunar craters The overwhelming majority of astronomers favors a meteor-impact origin for the giant fresh lunar craters. (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 ... -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. Some of the fresh craters on the mare borders, such as Aristarchus and Copernicus, are well-known sites of lunar transient phenomena. Could they be analogous to the terrestrial volcanos constituting the "ring of fire" around the Pacific Basin? From Science Frontiers ...

... 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 The Coming Revolution In Planetology "Current ideas about the moon appear to be mistaken on two fundamental points. First, at least within certain large classes of lunar craters, internal origin (i .e ., some form of volcanism) predominates over impact; this result raises questions about the reality of the 'era of violent bombardment.'Second, the origin of tektites by meteoric impact on the earth cannot be reconciled with physical principles and is to be abandoned. 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 ... 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." " Editor's Note . This article by John O'Keefe puts forth a viewpoint with which most planetologists disagree strongly. On the ground that a fresh airing of the long-standing discussion on lunar volcanism is appropriate, Eos offers this article, untouched by editors or referees, and awaits reply by readers." O'Keefe's article reviews considerable evidence supporting his two points: for Point One; crater dimensions ...
