Like the lead character of “Project Hail Mary,” some scientists are proposing ways that life might exist beyond a star’s “habitable zone,” often considered the gold standard of potential livability

Life on Earth is a precious thing, especially given what astronomers know about the visible universe. Although researchers have so far identified over 6,000 exoplanets beyond our

Out of the 6,000 known exoplanets, it's these rocky worlds that are most worthy of attention in the search for life beyond our planet.

Unlike our Moon, they can keep water in oceans liquid for more than 4 billion years.

A study from Cornell University discovered that a particular purple “light fingerprint” could be indicative of extraterrestrial life.

When it comes to the space sciences, nothing is quite as exciting as the search for alien life, and NASA thinks it has a good idea of where to look.

Scientists have identified 45 Earth-like exoplanets that are the strongest known candidates for hosting extraterrestrial life.

Recent observations suggest that scientists have identified potential microbial fingerprints in the atmospheres of other planets, raising intriguing questions about the possibility of alien life existing in the clouds. These findings, coupled with studies ...

Life may not get blasted off any of the known "super-Earth" worlds as readily as it can from our planet, scientists find. The discovery suggests that any intelligent aliens that develop on such planets might find it hard to rocket off them and travel to ...

If we discover alien life, what will it look like? We have no way of knowing, but the hunt for extraterrestrial life can now include purple bacteria, according to a group of astronomers who are recording the chemical makeup unique to the lavender-hued ...
