Although we normally think of water as key to life on Earth and elsewhere, it could actually be more difficult to find evidence of life on planets with immense stores of the stuff, a new study on the ...

Skip 39 light-years across our galaxy, and you’ll arrive at Trappist-1, an ultracool dwarf star with a band of special followers. This dim star hosts seven Earth-like planets within its habitable zone ...

The planets have been nicknamed Earth's seven sisters. — -- An international team of astronomers has discovered seven potentially habitable exoplanets — or planets outside our solar system — that ...

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 ...

The TRAPPIST-1 star system is home to seven Earth-size planets, and a new study suggests that 3 of those planets' atmospheres look similar to atmospheres found on rocky planets such as Venus or Mars.

The discovery of seven Earth-sized planets orbiting a (relatively) nearby dwarf star raises plenty of questions. Could they possibly harbor liquid water? What are the conditions like and what kind of ...

An astrophysics researcher has identified the possible compositions of the seven planets in the TRAPPIST-1 system. Using thousands of numerical simulations to identify the planets stable for millions ...

Back in February, NASA announced the discovery of seven Earth-sized exoplanets orbiting the nearby red dwarf star, TRAPPIST-1. With three of those planets orbiting within the star's Habitable Zone (HZ ...

Recent observations with the James Webb Space Telescope suggest that the innermost world of the TRAPPIST-1 system has no atmosphere — or at most, it’s extremely thinly veiled with the tattered ...

Scientists aren't the only ones excited about the discovery of seven Earth-size exoplanets around the star TRAPPIST-1. It turns out, the folks at Google are fans, too, and they celebrated with an ...
