There is life … and in our solar system! (Well is = might be).
scientists at the United States space agency NASA (National Aeronautics and Space Administration) believe that the vital clues they have discovered indicate the possibility for existence of early stages of aliens (primitive life forms) on Titan, one of the many moons orbiting planet Saturn.
According to researchers, Titan, the largest moon of Saturn, is the only one with a dense atmosphere, but the water on Titan’s surface is frozen and is too cold to support life. Though water is very necessary for any life to thrive, there has been extensive speculation about water being not a strict requirement because astrobiologists for sometime now, have been advocating theories about possible methane-based life.
Two new research papers based on the data sent from NASA’s Cassini spacecraft show hydrogen molecules flowing down through Titan’s atmosphere and disappearing at the surface, and lack of acetylene, an organic molecule that should be abundant in the moon’s thick atmosphere triggered by ultraviolet sunlight.
The findings have lead scientists to believe that something is consuming hydrogen gas and eating the organic molecule acetylene, which fits the hypothesis of methane-based life forms. However, scientists have emphasized that these findings are not proof of life and that a lot of work needs to be done to rule out possible non-biological explanations.
Don’t scoff — extraterrestrial life impossible, you say?
We reside in the Milky Way Galaxy, which boasts four hundred billion stars. From the movie Contact:
“You know, there are four hundred billion stars out there, just in our galaxy alone. If only one out of a million of those had planets, and just of out of a million of those had life, and just one out of a million of those had intelligent life; there would be literally millions of civilizations out there.”
I don’t think the math quite adds up … but it is a huge universe out there, and there are billions of galaxies.
(What’s four hundred billion times a billion? I don’t know, but it’s a lot of stars).
