There is growing evidence for the existence of life on other planets.
An astronomer breaks down 3 key components that allow researchers to make groundbreaking discoveries – and decide when results aren’t significant.
Looking at the history of ‘biosignature’ discoveries shows why they can be problematic.
Scientists will have to check whether the samples contain living microbes before they can be safely studied.
The discovery indicates water may have remained stable on Mars for much longer than scientists thought.
According to astronomers, there are approximately 200 billion trillion stars in our observable universe — chances are, there’s life out there somewhere.
‘Project Phoenix’ was initiated by small research organisation known as the SETI Institute. But it was lucky to get off the ground.
Only 10.2% of astrobiologists disagree with the claim that intelligent aliens likely exist.
Humans may still appear even if the universe were very different. In fact, we may not live in the most likely of possible universes.
On October 10, Europa Clipper will take off on a long journey to Jupiter’s moon Europa. The icy moon could potentially host alien life – and there’s only one way to find out.
