Astronomers have discovered four planets that are just a fraction of the mass of Earth orbiting Barnard’s Star, which is 6 ...

New James Webb Space Telescope (JWST) images show the first carbon dioxide-containing planet discovered outside of Earth’s ...

Scientists discovered that methyl halides, a gas produced by microbes, could be a biosignature for life on distant planets.

Our framework applies not only to Earth, but also other planets, increasing the possibility that life similar to ours could exist elsewhere.” ...

The study builds on previous research investigating different biosignature gases, including dimethyl sulfide, another ...

Astronomers have identified a quartet of small rocky planets orbiting Barnard's star - one of our closest stellar neighbors - ...

“Life might have originated very quickly once ... Astronomers could continue their observations of other planets to see how many host one of the hard step candidates, like oxygen-producing ...

“Our framework applies not only to Earth, but also other planets, increasing the possibility that life similar to ours could exist elsewhere.” The proposals of the paper, published in the peer ...

Penn State University researchers have said intelligent life on other planets might turn out to be a rule, rather than the exception. “This new perspective suggests that the emergence of ...

By untangling the forces that shape these distant worlds, we inch closer to answering some of humanity’s oldest questions: How common are planets like Earth? Is there other life among the stars?

The other is that those building blocks came ... the fraction of stars with planets and calculates the fraction of those planets where intelligent life may emerge. An optimistic estimate using ...

Astronomers have discovered that sulfur may be a key to helping us narrow down our search for life on other planets. It's not that sulfur is a great indication that a planet is inhabited.
