New simulations suggest TRAPPIST-1e's possible methane atmosphere may be a false signal from its star, raising fresh ...

The James Webb Space Telescope is able to peer closely at exoplanets one at a time and examine their atmospheres with unprecedented accuracy. But perhaps the most exciting planetary targets will be a ...

Recent measurements with the James Webb Space Telescope (JWST) cast doubt on the current understanding of the exoplanet Trappist-1 b's nature. Until now, it was assumed to be a dark rocky planet ...

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 ...

Skip 39 light-years across our galaxy, and you’ll arrive at Trappist-1, an ultracool dwarf star with a band of special followers. This dim star hosts seven Earth-like planets within its habitable zone ...
