I will accept a surprise. So far these boys set up to test for biological activity and saw what they were looking for. This potentially huge but for now we remain muted.
I am actually comfortable positing the interstellar world of comets as an incubator for lifeforms. I would like to see current activity, but i think that may take a human expedition or a much more complex robot able to swing a hammer.
To start with it eliminates whole lot of problems regarding gravity wells as traps. We do live in a rat trap. Yet comets do not at all and every time their parent star comes close to another star they readily exchange mass. Thus microbial life is capable of occuping the entire galaxy while continuously sharing DNA. They really are dirty ice balls of sorts.
This still does not solve the problem of life's origins, but it now makes the origination a Galactic problem rather that a Terran problem as a probable surety.
Alien Life May Have Been Discovered On Comet
Alien life may not be science fiction any more as a pair of top astronomers have claimed that life may have been discovered on a comet.
The Philae lander famously landed on the 67P comet last year and after examining pictures of the rock, scientists think they show signs of Microbial alien life.
Astronomer and astrobiologist Professor Chandra Wickramasinghe was involved with the mission to land Philae from the Rosetta space craft and made the game changing claims after studying the data.
He said: “What we’re saying is that data coming from the comet seems to unequivocally, in my opinion, point to micro-organisms being involved in the formation of the icy structures, the preponderance of aromatic hydrocarbons, and the very dark surface…
“Planets that can harbour life are really quite abundant in the galaxy, and the next neighbouring system to us is only spitting distance away.
“I think it’s inevitable that life is going to be a cosmic phenomenon.”
Professor Wickramasinghe said his plan from the very beginning was to find signs of life.
He added: “I wanted to include a very inexpensive life-detection experiment.
“At the time it was thought this was a bizarre proposition.”
Bizarre it may have been but he and colleague Dr Max Wallace are convinced that comets could be inhabited by living microbes.
A black crust on the comet has also been explained as being the result of organisms living beneath the icy surface.
The pair’s theory is that life on Earth may have been the direct result of life found on comets like 67P.
So basically we’re all aliens.
