Located about 39 light-years from Earth, the TRAPPIST system resembles a miniature version of our solar system: The star, an ultracool red dwarf, and all its planets would comfortably fit inside the ...

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 ...

The hunt is on for terrestrial exoplanets in habitable zones, and some of the most promising candidates were discovered almost a decade ago about 40 light-years from Earth. The TRAPPIST-1 system ...

Astronomers have taken a huge leap towards discovering habitable worlds, and the world now eagerly anticipates a rocky planet orbiting a faint star 40 light-years from home. Scientists are homing in ...

This artist’s concept shows the volatile red dwarf star TRAPPIST-1 and its four most closely orbiting planets, all of which have been observed by NASA’s James Webb Space Telescope (JWST). JWST has ...

At the beginning of the exoplanet age, the goals were fairly simple. The first was to find as many of them as possible to ...

Astronomers might be close to confirming the presence of an Earth-like atmosphere on an exoplanet for the first time, if more detailed analyses verify preliminary observations from the James Webb ...

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 ...

Like a toddler right before naptime, TRAPPIST-1 is a small yet moody star. This little star, which sits in the constellation Aquarius about 40 light-years from Earth, spits out bursts of energy known ...

JWST observations of exoplanet TRAPPIST-1d reveal a lack of a substantial, Earth-like atmosphere, as indicated by a "flat" spectral signature lacking typical atmospheric molecule fingerprints (e.g., ...

Seven recently discovered planets that are closely orbiting a dim star dubbed Trappist-1 are the best places to look for signs of life outside Earth, NASA and European scientists said Wednesday. There ...
