Discovery alert: With six new exoplanets, 5,500 discovery milestone passed
On Aug. 24, 2023, more than three decades after the first confirmation of planets beyond our own solar system, scientists announced the discovery of six new exoplanets, stretching that number to 5,502. From zero exoplanet confirmations to more than 5.....»»
Exoplanet caught in "hairpin turn" signals how high-mass gas giants form
Astronomers have discovered a planet that has the most oblong orbit ever found among transiting planets. The exoplanet's extreme circuit—which looks closer to a cucumber than a circle—follows one of the most drastically stretched-out orbits of al.....»»
Astronomers detect dozens of new pulsating white dwarfs
Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have detected 32 new bright pulsating DA white dwarfs of the ZZ Ceti subclass. The finding was reported in a research paper published July 9 on the pre-print server arXiv......»»
Webb investigates eternal sunrises, sunsets on distant world
Researchers using the James Webb Space Telescope have finally confirmed what models have previously predicted: An exoplanet has differences between its eternal morning and eternal evening atmosphere. WASP-39 b, a giant planet with a diameter 1.3 time.....»»
Nearby exoplanet could be first known ocean world: Webb telescope
A planet relatively close to Earth could be the first ever detected with a potentially life-sustaining liquid ocean outside our Solar System, according to scientists using the James Webb space telescope......»»
