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 ...

Are we alone in the universe? It's a question that has sparked curiosity in astronomers for generations. There are at least 6,000 known planets outside our Solar System (also known as exoplanets), but ...

The James Webb Space Telescope has achieved one of the first major science goals announced for it way back in 2017. The infrared instrument has now probed the atmosphere around one of the TRAPPIST-1 ...

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 ...

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 ...

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 ...
