Astronomers have been trying to detect atmospheres on planets orbiting TRAPPIST-1, but bursts of radiation from the star make this challenging ...

New TRAPPIST-1 observations with JWST underscore the complexities of confirming a planet's atmosphere using only broadband thermal emission data. This insight takes on added significance with the ...

TRAPPIST-1 is one of the smallest known M dwarfs, with a diameter of 52,300 miles (84,180 kilometers — just 12% of the sun's diameter — and 8.9% the sun's mass.

Seven Earth-sized planets circle TRAPPIST-1, an ultracool dwarf star that lies about 40 light-years away. With about 9% of our sun’s mass, this star is very small and dim.

TRAPPIST-1 is a red dwarf star located around 40.7 light years away from our solar system. Four of its seven planets are situated in the Goldilocks zone, ...

Trappist-1 is an ultracool dwarf star that flares less than younger stars, like our sun. Solar flares can damage nearby planets: A 2012 solar flare that tore through the Earth's orbit could have ...

TRAPPIST-1 is 39 light-years away from Earth, or about 229 trillion miles (369 trillion kilometers). It would take 39 years to get to its current location traveling at the speed of light.

The Trappist-1 system, with seven planets and their sun, is an extreme version of Poincaré’s three body problem (1890), which he was unable to resolve.

For comparison, he said, if Earth’s sun was the size of a basketball, TRAPPIST-1 would be roughly equivalent to a golf ball. Treasure trove of new planets found 10 photos.
