As another world around TRAPPIST-1 shows no signs of an atmosphere, astronomers urge us not to give up hope for an Earth-like atmosphere on one of the other worlds in the system.

Astronomers had hoped to observe an atmosphere on one of the seven planets known to orbit Trappist-1, a red dwarf star. A new ...

When global events set our minds to wondering if humanity has what it takes to persist, it's natural to wonder about other worlds, other life, other intelligent species, and if those others might be ...

Three out of seven Earth-sized planets in the TRAPPIST-1 system are likely without an atmosphere, ruling them out as ...

With seven rocky planets, the planetary system of TRAPPIST-1 is one of the most exciting of all. Now another one has turned out not to be Earth-like.

The TRAPPIST-1 planets are easier to measure because they orbit in sync; together, the seven exoplanets form a resonance chain connecting them all together and suggesting a slow, peaceful evolution.
