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 →
The site where NASA’s Mars rover Curiosity landed last year contains at least one lake that would have been perfectly suited for colonies of simple, rock-eating microbes found in caves and hydrothermal vents on Earth.
To avoid contaminating Mars with microbes from Earth, space agencies go through great expense to sanitize missions to Mars -- why bother? Continue reading →
Forget hunting for organic chemistry inside rocks on Mars or complex organisms in Europa's sub-surface oceans, the Cosmos has just FedEx'd some extraterrestrials direct to our door! Or not. ->
