Planets are bodies that orbit a star and have sufficient gravitational mass that they form themselves into roughly spherical shapes that, in turn, exert gravitational force on smaller objects around ...

The TRAPPIST-1 solar system generated a swell of interest when it was observed several years ago. In 2016, astronomers using the Transiting Planets and Planetesimals Small Telescope (TRAPPIST) at La ...

In a solar system called TRAPPIST-1, 40 light years from the sun, seven Earth-sized planets revolve around a cold star. Astronomers obtained new data from the James Webb Space Telescope (JWST) on ...

New work from a team of Carnegie scientists (and one Carnegie alumnus) asked whether any gas giant planets could potentially orbit TRAPPIST-1 at distances greater than that of the star’s seven known ...

The latest hunt for alien signals in the TRAPPIST-1 planetary system has test-driven a new strategy that will allow astronomers to perform a more efficient, targeted search for technological ...

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 ...

Astronomers obtained new data from the James Webb Space Telescope (JWST) on TRAPPIST-1 b, the planet in the TRAPPIST-1 solar system closest to its star. These new observations offer insights into how ...

Astronomers discovered the TRAPPIST-1 system, a family of tightly packed planets swarming a red dwarf star, about eight years ago. Credit: Mark Garlick / Science Photo Library / Getty Images ...

The star TRAPPIST-1 hosts seven worlds labeled Trappist-1 b through h. All the planets have sizes and masses comparable to the terrestrial planets in our own Solar System (that is, Mercury, Venus, ...
