A year after the discovery of seven Earth-size planets orbiting a star 40 light-years from Earth was announced, astronomers are revealing more details about the potentially habitable exoplanets.

As telescopes have become more powerful, we’ve been finding tons of “exoplanets”—planets orbiting faraway stars. One such planet, known as exoplanet TRAPPIST-1 d, has intrigued astronomers looking for ...

The hunt for intelligent life beyond Earth has quietly entered a more exacting phase, and one small, cool star has become a proving ground for how serious that search can be. TRAPPIST-1, a dim red ...

"This artist's concept shows what the TRAPPIST-1 planetary system may look like, based on available data about the planets' diameters, masses and distances from the host star, as of February 2018." ...

The discovery of the TRAPPIST-1 system stirred up excitement about a star system with three potentially habitable worlds, but recent observations of the innermost two planets have had discouraging ...

Churning magnetic activity on the surface of TRAPPIST-1's red dwarf star is interfering with the JWST’s efforts to determine whether any of the orbiting planets are habitable. When you purchase ...

In a solar system called TRAPPIST-1, 40 light years from the sun, seven Earth-sized planets revolve around a cold star. Astronomers obtained new data from the James Webb Space Telescope (JWST) on ...
