TRAPPIST-1 is one of the most fascinating planetary systems discovered so far. Located just 40 light-years away, seven roughly Earth-sized planets are orbiting a red dwarf star, with three of them ...

Scientists are observing an Earth-like exoplanet that may contain water using NASA's James Webb Space Telescope, the space agency said in a news release. The exoplanet, known as TRAPPIST-1 e, orbits ...

If aliens are watching Earth, they might be able to detect us from the radio signals we beam to Mars to control our rovers there. Astronomers have now listened in on the nearby TRAPPIST-1 system to ...

Ever since astronomers announced the discovery of seven exoplanets around the star called TRAPPIST-1, researchers have been diving into the data in an attempt to determine what the planets are like.

If you’re in the mood for a road trip and have a few hundred million years to kill, we have the destination for you. About 40 light-years away, orbiting a dim, cool red star called Trappist-1 are ...

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 ...

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 ...

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 ...

Scientists now say some of the TRAPPIST-1 planets could contain more water than even the oceans of the Earth—up to 250 times more. “Quite amazing,” says Simon Grimm, an astronomer with the Center for ...
