It seems not a day goes by without an announcement about a significant new discovery that brings us ever more closer to finding life, potentially within the confines of our solar system. In fact, in April this year, NASA chief scientist Ellen Stofan made the following comment during a press conference:
I think we’re going to have strong indications of life beyond Earth within a decade, and I think we’re going to have definitive evidence within 20 to 30 years
Stofan also appeared confident such indications of life would be evident in our own solar system. So bearing that in mind, I thought it would be quite interesting to consolidate some of the findings and see, if life is found in the solar system – what are the most likely places where it might appear? I am deliberately ignoring Mars for this as that is a post in itself due to the multiple variations of life available there (quick fact: Mars produces 270 tons of methane a year, of which only 0.8% of which is accountable by asteroid impact, so presence indicates that there must be an active source on the planet in order to keep such levels in the atmosphere…).
Located deep in our solar system, here are the celestial bodies where we are most likely to find alien life, in reverse order.
