Just 40 light-years from Earth, the TRAPPIST-1 system of planets is home to the largest family of Earth-like worlds known to astronomers. At least seven planets are known to orbit within the ...

Efforts to observe the atmospheres of planets in the TRAPPIST-1 system are being stymied by rambunctious activity on the surface of the red dwarf star at its center, new findings from the James Webb ...

This artist's concept shows what the TRAPPIST-1 planetary system may look like. TRAPPIST-1 fascinates planetary scientists. Just 39 light-years from us exist seven planets orbiting a star. It’s not an ...

Previously considered an airless ball, an Earth-sized world orbiting a red dwarf some 40 light-years away may have an atmosphere after all. New observations of planet b in the TRAPPIST-1 system reveal ...

TRAPPIST-1 is an ultra-cool dwarf with seven Earth-size planets orbiting it. (Photo digital Illustration by NASA/NASA via Getty Images) Scientists have just completed an extensive search for signs of ...

Astronomers obtained new data from the James Webb Space Telescope (JWST) on TRAPPIST-1 b, the planet in the TRAPPIST-1 solar system closest to its star. These new observations offer insights into how ...

Trappist-1, a star system 40 light-years away, holds seven Earth-sized planets—three in the habitable zone—that ignite our imagination about life beyond the solar system. But how long would it take to ...

"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." ...

Five years ago, astronomers revealed a spectacular collection of other worlds: the TRAPPIST-1 system. Newspapers around the world printed the discovery on their front pages: Astronomers had found that ...

New work from a team of Carnegie scientists (and one Carnegie alumnus) asked whether any gas giant planets could potentially orbit TRAPPIST-1 at distances greater than that of the star’s seven known ...
