Extremophiles are, as the name suggests, organisms that thrive in the most extreme physical environments. We are finding them almost everywhere we look on Earth, from deep in rocks, to hydrothermal vents at the bottom of oceans, to frozen deep in the arctic ice. Each find extends our knowledge of the conditions needed for life to survive, not just here but out in the Solar System and beyond. Jupiter's moon Europa, which has a salty ocean beneath a thick ice crust, is one of the most likely candidates for life in the Solar System. Researchers in Argentina have exposed salt-loving archae Natrialba magadii and Haloferax volcanii and radiation-resistant bacteria Deinococcus radiodurans to a vacuum & the intense ultraviolet radiation we think exists on Europa. Though no Haloferax volcanii survived.small amounts of both Natrialba magadii and Deinococcus radiodurans did.

Gotta be life everywhere! Very likely few places in our solar system have had or even will have life at some point :)
Some great missions are either planned or are currently looking for life, both in our Solar System and beyond. I am convinced that we will find definitive proof of life elsewhere within the next decade
Fascinating post! Amazing to think about the diversity of lifeforms!
Would be great on page 240 of Marcus Chown & Govert Schilling's new book! :-)
