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.

Astronomers using the James Webb Space Telescope are unraveling the mysteries of TRAPPIST-1e, an Earth-sized exoplanet 40 light years away that could harbor liquid water. Early data suggests hints of ...

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 ...

How will NASA's upcoming Habitable Worlds Observatory (HWO) mission differentiate Earth-sized exoplanets from other exoplanets, specifically Earth-sized exoplanets within the habitable zone, also ...

University of Bristol astrophysicists are helping shed new light on an Earth-sized exoplanet 40 light years away where liquid water in the form of a ...

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

Scientists got a never-before-seen look at an area around a large exoplanet 625 light-years away where moons could potentially form.

St. Andrews University physicists who looked at the planet said that the research conjures "two possible explanations." ...

NASA’s Transiting Exoplanet Survey Satellite (TESS) has been used to discover Earth-size planet TOI 700 e. It is "orbiting within the habitable zone of its star – the range of distances where liquid ...

It wasn’t until the ‘90s that our astronomical powers advanced enough to confirm the existence of worlds around other stars. Since that very first discovery, more than 6,000 exoplanets have been ...

NASA's James Webb Space Telescope has captured the first detailed chemical snapshot of a possible moon-forming disc around a giant exoplanet, researchers announced Monday. According to the newly ...
