For many years, mankind has wondered about the existence of life in worlds outside the Earth. It is possible though that alien life may indeed exist but not as we know it. In a new study published this week by researchers from Cornell University, the team of researchers has modeled a new methane-based life form that can metabolize and reproduce, similar to the oxygen-based life forms here on Earth.
Earlier this year, it has been identified a mysterious “ghost” object that had suddenly appeared and then disappeared on Saturn’s largest moon, Titan. Now, new observations by the Cassini team show this elusive feature is back again. Titan just got a little more mysterious.
Titan — that smoggy, orangy moon circling Saturn — is of great interest to exobiologists because its chemistry could be good for life.
