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 ...

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 ...

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 ...

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 ...

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 where ...

This artist's concept shows what the TRAPPIST-1 planetary system may look like. TRAPPIST-1 fascinates planetary scientists. Just 39 light-years from us exist seven planets orbiting a star. It’s not an ...

A second exoplanet in the TRAPPIST-1 system turns out to have no atmosphere, according to recent data from the James Webb Space Telescope (JWST), and that could be bad news for the search for life in ...

It's been almost a year since astronomers announced the discovery of seven Earth-sized exoplanets in the TRAPPIST-1 system. Just 40 light-years away, TRAPPIST-1 is one of the clearest case studies ...

Last year, NASA astronomers announced the discovery of a solar system with seven Earth-like planets. The TRAPPIST-1 system marked not only the highest number of Earth-like planets ever found around a ...

TRAPPIST-1 would be an unremarkable star if not for the scientific interest generated by its seven planets. Astronomers first spotted the new worlds, at least three of which might be habitable, in ...
