Forty light-years away, seven Earth-sized planets orbit around a dim red dwarf star in one of the most tightly packed planetary systems ever discovered. The TRAPPIST-1 system has captivated ...

Recent observations with the James Webb Space Telescope suggest that the innermost world of the TRAPPIST-1 system has no atmosphere — or at most, it’s extremely thinly veiled with the tattered ...

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 ...

TRAPPIST-1 just reminded us, again, that space is unforgiving. Last year, a team of astronomers used JWST to measure the starlight shining around the edges of TRAPPIST-1b as the rocky little planet ...

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 ...

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 ...

Astronomers have begun using the James Webb Space Telescope to study the TRAPPIST-1 solar system. Credit: NASA / JPL-Caltech Scientists have waited on pins and needles for more details about the ...

Several years ago, astronomers pointed a telescope at another star and discovered something remarkable: seven planets, each one about the same size as Earth. The planets were quite close to their ...
