Astronomers using data from the HATNet (Hungarian-made Automated Telescope Network) survey have discovered a transiting giant planet orbiting the K5-type dwarf star HAT-P-68.
Astronomers using the HARPS (High Accuracy Radial velocity Planet Searcher) spectrograph at ESO’s La Silla Observatory in Chile have detected gaseous magnesium (Mg), sodium (Na), calcium (Ca), chromium (Cr), iron (Fe), nickel (Ni) and vanadium (V) in the atmosphere of WASP-121b, a hot-Jupiter exoplanet approximately 881 light-years away in the constellation of Puppis.
The first results from ESA’s Characterising Exoplanet Satellite (Cheops) exoplanet mission has revealed one of the hottest and most extreme planets orbiting another star. Located 322 light years away in the constellation of Libra, WASP-189 b is an ultra-hot Jupiter with a temperature so high that iron boils into a gas.
Using NASA’s Transiting Exoplanet Survey Satellite (TESS) and two ground-based instruments, astronomers have discovered and confirmed a transiting hot Neptune exoplanet orbiting TOI-824, a K4-type dwarf star located 210 light-years away in the constellation of Circinus.
Astronomers using NASA’s Transiting Exoplanet Survey Satellite (TESS) have discovered a planetary system of two giant planets — a Neptune-sized planet and a hot Jupiter — orbiting the 8.2-billion-year-old star TOI-1130.
Astronomers from the University of Warwick have observed an exoplanet orbiting a star in just over 18 hours, the shortest orbital period ever observed for a planet of its type.
Astronomers say this planet is the hottest identified so far.
If confirmed, the shiny new worlds may help astronomers better understand how strange planets known as hot Jupiters are created.
An Earth-sized planet orbiting a dim star 39 light years away has a hazy atmosphere that could indicate the presence of a “water world”.
A FARAWAY world is steaming. Astronomers have found water vapour in the atmosphere of an exoplanet called 51 Pegasi b — and achieved the feat using a brand new technique.
