Talk about a tough neighborhood!
I'm Bob Karson with "The Discovery Files" -- new advances in science and engineering from the National Science Foundation.
Imagine life in a world where the temperature never gets below 95 degrees, and the acid level is so corrosive, it can dissolve nails. This inhospitable place is in the Norris Geyser Basin of Yellowstone National Park. There, inside pores in the rocks, scientists have found living creatures...a community of microbes thriving against all odds...sometimes getting life energy from dissolved metals and hydrogen.
Over the years, the bizarre life forms have fossilized, providing a clear picture of their past stages of development, and giving researchers important clues as to the possibility of life in other similar habitats...like what may have existed on Mars.
Astrobiologists consider this finding to be a key factor in steering our research of life forms throughout the entire solar system. Life...caught between a rock and a hot place.
