Following NASA’s latest discovery of organic matter on the red planet, new findings in a salt lake in California could point to where to look for alien life.
Planetary protection protocols try to make sure we don’t seed places like Mars with life from our planet. An astrobiologist argues they’re misguided – especially with human astronauts on the horizon.
If you want to live on Mars, you’re going to need to grow food. Seeds are naturally equipped to handle challenging Earth environments, but how well can they survive what they’ll encounter off-planet?
There has been much excitement this week about the possibility of water – and life – on some newly discovered exoplanets. But we can look closer to home for evidence of ET.
Complex life may be rare in the universe because most planets become either too hot or too cold before life has a chance to get a foothold. This might explain why we have yet to bump into E.T.
As far as underwhelming headlines go: “No Alien Life Found on Comet” must rank very close to the top. An article with this title appeared in the Guardian on July 6 in response to a story claiming that…
One of the many unanswered questions about the origin of life on Earth is: where did organic molecules – those containing carbon, from which life as we know it is derived – come from? Given the conditions…
Scientists have simulated the electrical energy produced in the Earth that may have led to life 3.5 billion years ago. Using a fuel cell, researchers from the University of Leeds and NASA’s Jet Propulsion…
Could life really exist on other planets? The most positive scientific answer we can offer is: well, maybe, but we do not yet have enough evidence for or against. Yet Milton Wainwright and colleagues from…
