WASHINGTON, March 3 (UPI) -- Scientists have found more evidence to support theories that water and microbial life once existed on Mars. Scientists at NASA’s Johnson Space Center in Houston located the proof while studying a meteorite that fell from Mars and landed in Antarctica about 50,000 years ago
In analyzing the Martian meteorite, known as Yamato 000593 (Y000593), NASA researchers -- with the help of Japanese astronomers, who first located the meteorite -- determined the rock to be 1.3 billion years old. Inside the layers of ancient space rock, scientists found tiny "micro-tunnels," as well as little glob-like carbon deposits. The shapes and curves of tunnels suggest they are the product of bio-alterations, textures which are similar to interactions observed between bacteria and basaltic materials on Earth.
