TRAPPIST-1 is an ultracool M-type red dwarf star sitting just 40 light years from the sun. ... TRAPPIST-1f, stretches some 125 miles deep, ...

Recent JWST observations reveal there's no atmosphere, or at best, a very thin one, on the second exoplanet in the TRAPPIST-1 system. ... Trappist-1f. All of the planets and the Sun are to scale.

This image provided by NASA/JPL-Caltech shows an artist’s conception of what the surface of the exoplanet TRAPPIST-1f may look like, based on available data about its diameter, mass and ...

Two of TRAPPIST-1’s planets are half water and ice, ... TRAPPIST-1f, liquid water extends down about 200 kilometers — about 20 times deeper than the Mariana Trench on Earth.

On TRAPPIST-1b, no one can hear you scream (because there is no air, according to a recent study). Menu. space. ... Trappist-1f. All of the planets and the Sun are to scale.

Researchers from School of Earth and Space Exploration at Arizona State University say there might actually be too much water for the TRAPPIST-1 planets to harbor life.

TRAPPIST-1f, g and h lie far enough from their host star that water could be frozen into ice across their surfaces. The thin atmospheres would probably lack the heavier molecules found on Earth. ...

Solar flares, blasts of plasma gasses of solar energy might shape the short-term weather on distant planets according to a new study.

These planets, which are currently hypothesized to be Earth-sized and rocky worlds, include TRAPPIST-1b, TRAPPIST-1d, TRAPPIST-1e, TRAPPIST-1f, TRAPPIST-1g, and TRAPPIST-1h, with TRAPPIST-1b ...

Trappist-1f, the next closest planet to its host star, has 0.7 times the mass of Earth, and is likely to be moderately wet or wet. Both planets appear to have ended up covered by thick oceans and ...

A new study of several planets in the habitable zone of the star TRAPPIST-1 suggests that the planets' atmospheres look similar to those found on rocky ... TRAPPIST-1d, TRAPPIST-1e and TRAPPIST-1f.

The James Webb Space Telescope has measured the temperature of a rocky exoplanet for the first time, finding that a "cousin" of Earth most likely lacks an atmosphere, researchers said Monday.
