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 ...

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 ...

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

TRAPPIST-1 looks small and calm from Earth. Up close, it is anything but. The cool red star about 40 light-years away erupts with bursts of energy many times each day, sending radiation racing across ...

There's bad news for our hopes of habitable planets existing around TRAPPIST-1, with the James Webb Space Telescope (JWST) finding no evidence for an Earth-like atmosphere on a third world orbiting ...

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 ...

Scientists are observing an Earth-like exoplanet that may contain water using NASA's James Webb Space Telescope, the space agency said in a news release. The exoplanet, known as TRAPPIST-1 e, orbits ...

While late M-stars are the easiest places to find Earth-sized planets, a new study suggests they are biological dead ends where animal life may never find enough fuel to evolve.

As telescopes have become more powerful, we’ve been finding tons of “exoplanets”—planets orbiting faraway stars. One such planet, known as exoplanet TRAPPIST-1 d, has intrigued astronomers looking for ...
