The Jovian system has four large moons, including the largest moon in the Solar System, Ganymede, whereas the Saturnian system is dominated by one giant...
Using the Near-Infrared Spectrograph (NIRSpec) onboard the NASA/ESA/CSA James Webb Space Telescope, astronomers have characterized the atmosphere of TOI-5205b,...
Using the Immersion Grating Infrared Spectrometer (IGRINS) on the Gemini South telescope at the International Gemini Observatory, astronomers have directly...
A new analysis of isotopic signatures across planets and meteorite parent bodies suggests our home world formed entirely from inner solar system material,...
By combining infrared observations from the NASA/ESA/CSA James Webb Space Telescope with visible-light imagery from the NASA/ESA Hubble Space Telescope,...
Using ESO’s Very Large Telescope (VLT) and VLT Interferometer (VLTI) in Chile, astronomers have directly observed two gas giants emerging from the planet-forming...
Kepler-51 is a young G-dwarf star hosting three super-puffs and one low-mass non-transiting exoplanet. Kepler-51d, the coolest transiting planet in this...
The NASA/ESA/CSA James Webb Space Telescope conducted a clockwise scan around the entire limb of Jupiter, chasing aurora as it rotated into view. This...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have for the first time identified hydrogen sulfide gas in the atmospheres of three gas-giant...
A new analysis of data from four instruments aboard NASA’s Cassini spacecraft has demonstrated the crucial role that Saturn’s small icy moon Enceladus...
Using high-precision radio-occultation measurements from NASA’s Juno mission and incorporating the effects of zonal winds, planetary scientists derived...
New research by MIT planetary scientists shows how striking differences in the polar vortex patterns of Jupiter and Saturn may be driven by deep interior...
PSR J2322-2650b, an enigmatic Jupiter-mass exoplanet orbiting the millisecond pulsar PSR J2322-2650, appears to have an exotic helium-and-carbon-dominated...
Using high-precision spectroscopic observations from the Near Infrared Imager and Slitless Spectrograph (NIRISS) onboard the NASA/ESA/CSA James Webb Space...
At the end of their main-sequence life span, stars similar in mass to our Sun will undergo a period of evolution. This stellar evolution is predicted to...
The new map of WASP-18b, a hot-Jupiter exoplanet located approximately 325 light-years from Earth, reveals an atmosphere with distinct temperature zones...
The discovery of 1I/Oumuamua, 2I/Borisov and 3I/ATLAS showed that significant numbers of interstellar objects populate interstellar space. Their omnipresence...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have found the carbon-rich disk surrounding CT Cha b, a giant exoplanet around 620 light-years...
Astronomers using the NASA/ESA James Webb Space Telescope have detected a series of dark, bead-like and asymmetric star-shaped features in the ionosphere...
