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.
A still-forming planet has been detected early in its birth process, thanks to what may have been a chance encounter with a passing star that flipped part of the obscuring disk out of the way, exposing the baby planet.
In recent years, astronomers have developed techniques to measure the metal content of stars with extreme accuracy.
An international team has discovered a new multi-planet system around a sun-like star, including an ultra-short period planet with one of the highest densities ever measured.
A new NASA-led study suggests that a potential exomoon may be orbiting the exoplanet WASP-49 b, a gas giant located 635 light-years from Earth. The possible exomoon is believed to be rocky and volcanically active, similar to Jupiter's Io.
Using the European Southern Observatory's Very Large Telescope, astronomers have discovered an exoplanet orbiting Barnard's star, the closest single star to our Sun.
WASP-76b is tidally locked to its host star, so intense winds encircle the planet. They contain high quantities of iron atoms that stream from the lower to upper layers around the atmosphere.
