By tracking fierce winds racing through the atmospheres of seven ultra-hot Jupiters, astronomers have uncovered the strongest evidence yet that magnetic...
Using the Immersion Grating Infrared Spectrometer (IGRINS) on the Gemini South telescope at the International Gemini Observatory, astronomers have directly...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have detected water, carbon monoxide, and silicon monoxide in the dayside atmosphere of WASP-121b...
Ultrahot Jupiters, an extreme class of planets not found in our Solar System, provide a unique window into atmospheric processes. Using four telescope...
Astronomers using the Immersion GRating INfrared Spectrograph (IGRINS) instrument on the Gemini South telescope have examined the atmosphere of WASP-121b,...
Using data from ESA’s Characterising ExOplanet Satellite (CHEOPS) and several other ESA and NASA missions, astronomers have detected signs of the rainbow-like...
Astronomers using the NASA/ESA Hubble Space Telescope have detected massive cyclones and other dynamic weather activity swirling on WASP-121b, an ultrahot-Jupiter...
Young moving stellar groups are the best targets for direct imaging of exoplanets and four massive Jupiter-like planets have been already discovered in...
Terbium, a chemical element with the symbol Tb and atomic number 65, has never before been seen in an exoplanet atmosphere.
This illustration shows how...
Barium, a chemical element with the symbol Ba and atomic number 56, is the heaviest element detected to date in any exoplanetary atmosphere.
This artist’s...
It’s raining vaporized rock on WASP-178b, and KELT-20b has its upper atmosphere getting hotter rather than cooler because it is being sunburned by intense...
Using data collected by the Wide Field Camera 3 (WFC3) infrared spectrograph onboard the NASA/ESA Hubble Space Telescope, astronomers have obtained a detailed...
The temperature of a planet’s atmosphere decreases with increasing altitude, unless a shortwave absorber that causes a temperature inversion exists....
Using high-resolution spectra obtained with GRACES at the Gemini North Observatory, astronomers have detected ionized calcium in the atmosphere of the...
Astronomers have discovered a highly-irradiated gas giant exoplanet in close-in, highly misaligned orbit around a bright star called TOI-1518.
An artist’s...
Astronomers have discovered evidence for a giant planet orbiting Vega, a young star located 25 light-years away in the constellation of Lyra.
An artist’s...
Because of its proximity to its parent star, the dayside equilibrium temperature of the ultrahot Jupiter WASP-189b reaches 3,162 degrees Celsius (5,724...
New observations from NASA’s Transiting Exoplanet Survey Satellite (TESS) have enabled astronomers to improve their understanding of the bizarre environment...
