New Study Challenges Planet Formation Models with PDS 70b’s Chemical Mystery

New research on PDS 70b, a forming exoplanet located approximately 400 light-years away in the constellation Centaurus, suggests that prevailing models of planet formation may require revision. According to a study published in Astrophysical Journal Letters, astronomers found a mismatch between the chemical composition of the planet’s atmosphere and the surrounding protoplanetary disk from which … Read more

Astronomers Discover Water and Carbon Dioxide in WASP-166 b’s Atmosphere

Astronomers have analysed the atmosphere of WASP-166 b, a hot super-Neptune exoplanet, revealing the presence of water and carbon dioxide. Using data from the James Webb Space Telescope (JWST), the observations also detected ammonia in smaller quantities. WASP-166 b is situated approximately 368 light-years away and is about seven times larger and 32 times heavier … Read more

NASA observes a planet crumbling at record speed, BD+05 4868 Ab

Astronomers have identified the fastest disintegrating exoplanet observed to date, a discovery made possible by NASA’s Transiting Exoplanet Survey Satellite (TESS). The planet BD+05 4868 Ab, located approximately 141 light-years from Earth, is being eroded at an extraordinary rate due to intense bombardment from its host star, BD+05 4868 A. The planet is losing mass … Read more
