Ancient Fossils in Meteorite Discovered!

  Algae-like structures inside a Sri Lankan meteorite are clear evidence of panspermia, the idea that life exists throughout the Universe, say astrobiologists. A piece of the Sri Lankan meteorite, called the Polonnaruwa Meteorite, that crashed Dec. 29, 2012 near the village of Polonnaruwa (Sri Lanka).

The Hunt for Extraterrestrial Amino Acids

  The hunt for the organic molecules that create proteins and enzymes critical for life here on Earth has largely happened in sophisticated terrestrial laboratories equipped with high-tech gadgetry needed to tease out their presence in space rocks and other extraterrestrial samples. This is an example of chirality of amino acids, using hands to illustrate [continue reading]

Meteorites Reveal Warm Water Existed on Mars

  Hydrothermal fractures around Martian impact craters may have been a habitable environment for microbial life   The study determined that water temperatures on the Red Planet ranged from 50°C to 150°C. Microbes on Earth can live in similar waters, for example in the volcanic thermal springs at Yellowstone Park, the scientists behind the research point [continue reading]
