Earth Ejecta Could Seed Life On Europa
KentuckyFC writes "Various astronomers have studied how far rocks can travel through space after being ejected from Earth. Their conclusion is that it's relatively easy for bits of Earth to end up on the Moon or Venus, but very little would get to Mars because it would have to overcome gravity from both the Sun and the Earth. Now, the biggest ever simulation of Earth ejecta confirms this result — with a twist. The simulation shows that Jupiter is a much more likely destination than Mars. So bits of Earth could have ended up on Jovian satellites such as Europa. Astrobiologists estimate that Earth's hardiest organisms can survive up to 30,000 years in space, which means that if conditions are just right, Earth ejecta could seed life there."
How about "The Earth's Life Giving Goo could land on Europa's Face"
the seeds of life are simply everywhere, inside and outside the solar system, and life is simply always lying dormant, everywhere in the galaxy
I'd say the elements of life are everywhere, but not the seeds. Having the material but not the proper information is not enough. Life is composed by amino acids, but those are merely the bricks used to make proteins. One must have a suitable floor plan to build a house.
What makes conditions on early earth so special is not the existence of organic chemistry, but the special circumstances, so far not known to us, that brought the formation of complex self-reproducing chains of amino acids.
