A young American scientist searching for intelligent aliens across the seven Earth doppelgängers that circle the red dwarf star TRAPPIST-1 says that if this wondrous solar system holds an ...

However, a geologically active planet also explains the data. Trappist-1 b is one of seven rocky planets orbiting the star Trappist-1, located 40 light-years away. The planetary system is unique ...

Astronomers discovered the TRAPPIST-1 system, a family of tightly packed planets swarming a red dwarf star, about eight years ago. Credit: Mark Garlick / Science Photo Library / Getty Images ...

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 ...

"I would imagine that all Trappist-1 planets are going to have a hard time holding on to any atmosphere." Scientists have discovered that a potentially habitable planet is having its atmosphere ...

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 ...

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. Efforts to observe ...

At about 40 light-years from Earth, there is the TRAPPIST-1 system. Seven Earth-sized worlds orbit very close to a red dwarf, much dimmer and cooler than our Sun. Three of these worlds might have ...

Home to seven mysterious planets—each around the size of our own Earth—the TRAPPIST-1 system is regarded by some as the crown jewel of astronomy’s efforts to find life in the Milky Way.

About 40 light-years away from Earth, in the constellation Aquarius, floats TRAPPIST-1, the most studied planetary system outside our own. Three of its seven planets lie within a habitable zone ...
