Researchers said on May 20, 2025, that there could be abundant water on the seven worlds.
New views of TOI-421 b by JWST gives insight into how the most common type of planet in the galaxy might form.
Astronomers using the James Webb Space Telescope have directly detected the faint glow of a planet that’s colder than any world whose light has been directly observed.
Earth-like exoplanets might be more common throughout the Milky Way than previously believed, astronomers report in a new study.
An astronomer at Columbia University is suggesting that because life emerged so soon on Earth after its formation, it may emerge rapidly on Earth-like planets after the right conditions arise in general.
Astronomers have detected the most promising signs yet of a possible biosignature outside the solar system, although they remain cautious.
Astronomers at MIT have discovered a rocky exoplanet orbiting the bright K-dwarf star BD+05 4868A and observed variable transit depths that are characteristic of comet-like tails.
A combination of cosmic processes shapes the formation of one of the most common types of planets outside of our solar system, according to a new study.
Astronomers using the Near-Infrared Camera (NIRCam) onboard the NASA/ESA/CSA James Webb Space Telescope have captured coronagraphic images of the HR 8799 and 51 Eridani planetary systems.
Exciting new research suggests there are four miniature planets orbiting Barnard's Star, each thought to be just 20 to 30% the mass of Earth.
Speedy’ planets orbiting faster in smaller orbits around white dwarfs are warmer than expected and more likely to maintain habitable conditions than the planets around the sun-like stars.
The planet, WASP-121b, is some 900 light-years away in the constellation Puppis. The team has now probed deep inside Tylos's atmosphere and revealed distinct winds in separate layers, forming a map of the atmosphere's 3D structure.
A Canadian-led team of international astronomers has made a groundbreaking discovery about how young planets form and grow using a creative approach with unique tools of the James Webb Space Telescope.
An international team has confirmed the discovery of a super-Earth orbiting in the habitable zone of a nearby Sun-like star.
Astronomers have found two planets around two separate stars that are succumbing to their stars' intense heat. Both are disintegrating before our telescopic eyes, leaving trails of debris similar to a comet's.
