This astrobiology article reports another case for ancient life on Mars – a meteorite from Mars peppered with tiny magnetic crystals that on our planet are only made by bacteria. A transmission electron microscope image shows magnetite crystals in the Allan Hills meteorite (ALH84001), which landed in Antarctica about 13,000 years ago. The article features Dr. Everett Gibson and discusses the implications of this discovery. Numerous links are provided to supporting information and related articles.
