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.
New data from James Webb Space Telescope and simulation models have confirmed a new type of planet unlike anything found in the Solar System.
Winds circling a gas giant more than 500 light years from Earth have been detected flowing at supersonic speeds approaching 33,000 kilometers per hour, making them the fastest air currents on any known planet by a wide margin.
When examining a still-developing exoplanet in a distant star system, a team of astronomers uncovered a mismatch between the gases in the planet's atmosphere and those within the disk.
An unusual planetary system with three known ultra-low density "super-puff" planets has at least one more planet.
Data from 2023 soured hopes that a nearby exoplanet had a habitable atmosphere. That disappointment might have been premature.
