Forty light-years away, seven Earth-sized planets orbit around a dim red dwarf star in one of the most tightly packed ...

A seven-planet system some 40 light-years from Earth could be swimming in water, new research shows. In February 2017 scientists announced the discovery of several exoplanets orbiting the red dwarf ...

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 ...

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 ...

The latest hunt for alien signals in the TRAPPIST-1 planetary system has test-driven a new strategy that will allow astronomers to perform a more efficient, targeted search for technological ...

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 ...

There's bad news for our hopes of habitable planets existing around TRAPPIST-1, with the James Webb Space Telescope (JWST) finding no evidence for an Earth-like atmosphere on a third world orbiting ...

Astronomers have been keenly interested in the TRAPPIST-1 system ever since the Spitzer Space Telescope identified an incredible seven Earth-like exoplanets in orbit of the star. They might not be as ...

Frequent flares from the nearby star TRAPPIST-1 could offer new clues in the search for habitable planets beyond Earth. TRAPPIST-1 is an ultracool red dwarf, located about 40 light-years away in the ...

TRAPPIST-1 looks small and calm from Earth. Up close, it is anything but. The cool red star about 40 light-years away erupts with bursts of energy many times each day, sending radiation racing across ...
