A shadow and grid-like pattern.

"...the recent Phobos probe that the Russians sent to Mars in 1988 -- which met a mysterious and untimely demise -- recorded two quite mysterious Anomalies on the planet before contact was lost with the satellite. One was a strange shadow moving across the planet's surface (not a shadow of either of Mars' moons)! The other anomaly was a strange grid-like pattern at one location on the Martian surface; it was photographed with an infrared camera on Phobos 2, the first such instrument carried on a spacecraft sent to Mars." (Ref. 1)

The canals are still there -- in a shadowy way ! Commenting upon the theory that those Martian canals that keep showing up on plates made through terrestrial telescopes are only picture/film defects, D. Louderback points out that the:

"...canals are also showing up on CCD [Charge-Coupled Device] camera photos like the one taken by Donald Parker with a 12.5-inch reflector and shown on the cover of the Strolling Astronomer earlier this year. It clearly showed a pentagonal pattern of canals surrounding Elysium. It is almost certain that these were not a 'picture defect'!" (Ref. 1)

Searching for explanations, J. Gallagher has discovered that many of the prominent canals drawn by Lowell, Schiaparelli, et al, actually closely follow contour lines drawn on USGS maps of Mars from Viking data. It is quite possible, then, that the "canals" are really only elevational differences in Martian topography. (Ref. 2)

Global Cooling. The Hubble Space Telescope recently photographed Mars when the planet was nearly totally shrouded by high cirrus clouds. Mars is now cloudier than it has been for years. The reason for this is that the planet's average temperature has fallen by almost 20C. What little water vapor exists in the atmosphere freezes out into cirrus clouds. Why has Mars cooled so drastically? Because the huge dust storms of the Viking years have mysteriously abated. Now, we have to explain why dust storms no longer envelope the planet! (Ref. 3)

Science Frontiers Sourcebook Project Reviewed in:


  • "A sourcebook of unexplained phenomena is therefore a valuable addition to a collection of scientific literature. William R. Corliss has provided this in the past with his source books of scientific anomalies in several subjects, and now he has provided it for astronomy. He has done an excellent job of collecting and editing a large amount of material, taken in part from scientific journals and in part from scientific reporting in the popular or semi-scientific press." -- "The Mysterious Universe: A Handbook of Astronomical Anomalies", reviwed by Thomas Gold, Cornell University, in Icarus, vol.41, 1980

  • "An interesting, systematic presentation of unusual weather [..] This book is recommended for a general audience" --"Corliss, William R., Tornados, Dark Days, Anomalous Precipitation, and Related Weather Phenomena, Sourcebook Project, 1983.", revieweed in Choice, September 1983
  • "..the science is necessarily somewhat speculative, but Corliss's symthesis is based on reputable sources." -- "Corliss, William R. (Compiler). Lightning, Auroras, Nocturnal Lights, and Related Luminous Phenomena" reviwed by Joseph M. Moran, Univ. of Wisconsin in Science Books and Films, Sep/Oct 1983

  • "Before opening the book, I set certain standards that a volume which treads into dangerous grounds grounds like this must meet. The author scrupulously met, or even exceeded those standards. Each phenomenon is exhaustively documented, with references to scientific journals [..] and extensive quotations" -- "Book Review: The moon and planets: a catalog of astronomical anomalies", The Sourcebook Project, 1985., Corliss, W. R., Journal of the Royal Astronomical Society of Canada, Vol. 81, no. 1 (1987), p. 24., 02/1987
