It could be that the plucky rovers we've sent to explore the Red Planet have brought with them unwelcome, hitchhiking bacteria.
A series of laboratory tests show that some terrestrial bacteria would adapt well to the salty and sulfate-rich ocean believed to exist beneath the hard icy shell of Europa.
Methane, a potential sign of primitive life, has been found in meteorites from Mars, adding weight to the idea that life could live off methane on the Red Planet.
Outer space might be the toughest environment for life, but some hardy microbes have been able to survive in it for surprising amounts of time.
In our continuing fascination for Mars and its past habitable potential, scientists are now focusing on a possible red planet oasis where liquid water may have been stored underground and heated by a volcano. Continue reading →
In experiments on terrestrial methane-producing microorganisms, researchers have found that they can survive Mars-like temperature extremes. Continue reading →
The space station is about to get many, many new visitors onboard. These unlikely space travelers won't have their names in the history books, though they have come from somewhere near you. Maybe even from on you. Continue reading →
