As another world around TRAPPIST-1 shows no signs of an atmosphere, astronomers urge us not to give up hope for an Earth-like ...

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

The exoplanet TRAPPIST-1 d intrigues astronomers looking for possibly habitable worlds beyond our solar system because it is ...

The TRAPPIST-1 system, home to seven Earth-sized planets orbiting a red dwarf star, has long been a target for astronomers studying potentially habitable exoplanets. Among these, TRAPPIST-1 d stood ...

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.

One such planet, known as exoplanet TRAPPIST-1 d, has intrigued astronomers looking for possibly habitable worlds beyond our ...

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

Université de Montréal doctoral graduate Caroline Piaulet-Ghorayeb and her team are unequivocal: TRAPPIST-1 d, the third ...

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.

At 40 light years away from Earth, TRAPPIST-1's four Goldilocks zone planets are one of the prime candidates for finding extra-terrestrial life.

Scientists model the planets around Trappist-1 and decide that if there's life on one of these planets, there's probably life on more than one of them. Eric Mack has been a CNET contributor since ...

TRAPPIST-1 is an ultracool M-type red dwarf star sitting just 40 light years from the sun. Seven planets have been discovered orbiting the star, of which at least three are sitting in the star's ...
