A survey of ultracool dwarf stars finds they don’t emit enough UV light to kick-start life, but they could reveal other ways for life to get going.

Ever since astronomers announced the discovery of seven exoplanets around the star called TRAPPIST-1, researchers have been diving into the data in an attempt to determine what the planets are like.

Astronomers know of about 60 rocky exoplanets orbiting in the habitable zones of their stars. When they try to determine how ...

The number of confirmed exoplanets — planets orbiting stars other than the sun — has risen to 5,539, with 10,000 more candidates under review. Most of these are in the Milky Way, though scientists ...

Although TRAPPIST-1 is 40 light-years away, its remarkable similarities to our own solar system make the discovery very exciting to scientists. Of all the solar systems we know of, we've never ...

Astronomers have discovered six exoplanets orbiting a nearby star in harmonic rhythm — called resonance — that could shed ...
