With the discovery of ever more exoplanets—over 6,000 now—scientists, of course, want to know if they are habitable for life. (At least, life as we know it.) But assessing habitability is a difficult ...

A new study rules out the existence of global oceans of water on Neptune-like planets such as K2-18b, finding their water usually sinks.

An exoplanet orbiting a dwarf star 124 light-years from Earth made headlines around the world in April 2025. Researchers at the University of Cambridge reported that planet K2-18b could be a marine ...

The striking thing about this is that repeating the procedure on the star turned up no evidence of carbon-based chemicals, even though the system is young enough that it should still have a ...

But those claims were quickly met with pushback. Independent analyses of the same JWST data suggested the team's evidence for DMS was weak at best, while other experts cautioned that sub-Neptunes may ...

Exoplanet TRAPPIST-1 e may contain an atmosphere and liquid water, NASA scientists said. Research into the exoplanet is ongoing.

Trump posted about a medical conspiracy theory called 'medbeds.' Here's what's going on.

JWST data hints that Trappist-1e may have an atmosphere. More transits will test if this world could support liquid water. Recent observations with NASA’s advanced JWST telescope have revealed a ...
