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 ...

One of seven planets orbiting a small star, TRAPPIST-1, may be capable of supporting life as we know it on Earth, new climate models suggest. Located 39 light-years away from Earth, TRAPPIST-1 is a ...

39 light years from Earth, the TRAPPIST 1 system hides one of the most extraordinary planetary families ever discovered.

About 40 light-years away from Earth, in the constellation Aquarius, floats TRAPPIST-1, the most studied planetary system outside our own. Three of its seven planets lie within a habitable zone where ...

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 ...

A small, cool star in distant space plays host to something amazing. Scientists have discovered that at least seven Earth-sized worlds circle the star TRAPPIST-1, a ultracool dwarf star only about 40 ...

TRAPPIST-1 just reminded us, again, that space is unforgiving. Last year, a team of astronomers used JWST to measure the starlight shining around the edges of TRAPPIST-1b as the rocky little planet ...

A second exoplanet in the TRAPPIST-1 system turns out to have no atmosphere, according to recent data from the James Webb Space Telescope (JWST), and that could be bad news for the search for life in ...

Could the system of seven Earth-size planets 40 light-years away host ETs? Some researchers argue they could some day, if they don't already. Eric Mack has been a CNET contributor since 2011. Eric and ...
