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 ...

Trappist-1 is a fascinating exoplanetary system. Seven worlds orbiting a red dwarf star just 40 light-years away. All of the worlds are similar to Earth in mass and size, and three or four of them are ...

Astronomers have begun using the James Webb Space Telescope to study the TRAPPIST-1 solar system. Credit: NASA / JPL-Caltech Scientists have waited on pins and needles for more details about the ...

TRAPPIST-1e, an Earth-sized world in the system’s habitable zone, is drawing scientific attention as researchers hunt for signs of an atmosphere—and potentially life-supporting conditions. Early James ...

"The TRAPPIST-1 system is special because it hosts seven approximately Earth-sized planets that exist in orbital locations interior to, within, and outside of the habitable zone, where liquid water ...

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 ...

This illustration shows what the TRAPPIST-1 planetary system may look like, based on available data about the planets’ diameters, masses, and distances from the host star. Astronomers have named them ...

The 2015 discovery of the TRAPPIST-1 system, with its seven Earth-sized planets, has redirected much of the exoplanet search toward M-dwarf systems — and justifiably so. Based on Kepler data, ...

The hunt for intelligent life beyond Earth has quietly entered a more exacting phase, and one small, cool star has become a proving ground for how serious that search can be. TRAPPIST-1, a dim red ...

Five years ago, astronomers revealed a spectacular collection of other worlds: the TRAPPIST-1 system. Newspapers around the world printed the discovery on their front pages: Astronomers had found that ...
