It’s not “little green men,” but rather little bitty particles that have the scientific community buzzing about NASA's announcement today that the Mars Curiosity rover has found what's being called the "building blocks" for life and methane in the planet's atmosphere.
It seems the rover found organic matter that’s over three-billion years old and researchers say that this discovery puts them in a good place to look for signs of life.
Researchers say that more analysis must be done to see if their discovery comes from organic life or from a geological process.
"These results do not give us any evidence of life," stressed study lead author Jennifer Eigenbrode [[EYE-gen-brode]], a scientist at the Solar System Exploration Division at NASA's Goddard Space Flight Center. "But there is a possibility that [the organics] are from an ancient life source; we just don't know.”
