OK Enough is enough - Now you’re talking about magnets and Martians?? Well - yes we are..magnets here, magnets there (mars) magnets everywhere ......Be careful you might start believing this stuff about magnets if you read on......
December 20, 2000 -- The case for ancient life on Mars looks better than ever after scientists announced last week that they had discovered magnetic crystals inside a Martian meteorite -- crystals that, here on Earth, are produced only by microscopic life forms.
The magnetic compound, called magnetite or Fe3O4, is common enough on our planet. It is present, for example, in household video and audio tapes. But only certain types of terrestrial bacteria, which can assemble the crystals atom by atom, produce magnetite structures that are chemically pure and free from defects.
Scientists studying the Allan Hills meteorite, a 4-billion-year-old rock from Mars that landed in Antarctica about 13,000 years ago, found just such crystals deep inside the space rock................READ ON..............http://science.nasa.gov/headlines/y2000/ast20dec_1.htm
