A carbon-rich substance found filling tiny cracks within a Martian meteorite could boost the idea that life once existed on the Red Planet.
The material resembles that found in fractures, or "veins", apparently etched by microbes in volcanic glass from the Earth's ocean floor. The evidence comes from a meteorite held in London's Natural History Museum that was cracked open by curators. ... Details will be presented at the Lunar and Planetary Science Conference in Houston, Texas, next month. The research team includes scientists who brought evidence for microbial life in another Martian meteorite, ALH84001, to the world's attention in 1998 [1996, actually]. ... Fresh samples The latest data comes from examination of a piece of the famous Nakhla meteorite which came down in Egypt, in 1911, breaking up into many fragments. [It also hit and killed a dog, supposedly: http://www2.jpl.nasa.gov/snc/nakhla.html] The full article is here: http://news.bbc.co.uk/2/hi/science/nature/4688938.stm Includes links to the papers. -------------------- "After having some business dealings with men, I am occasionally chagrined,
and feel as if I had done some wrong, and it is hard to forget the ugly circumstance. I see that such intercourse long continued would make one thoroughly prosaic, hard, and coarse. But the longest intercourse with Nature, though in her rudest moods, does not thus harden and make coarse. A hard, sensible man whom we liken to a rock is indeed much harder than a rock. From hard, coarse, insensible men with whom I have no sympathy, I go to commune with the rocks, whose hearts are comparatively soft." - Henry David Thoreau, November 15, 1853 |
