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...
Using data from NASA’s Juno spacecraft, planetary researchers have detected a new type of plasma wave in the auroral zones above Jupiter’s north pole.
This...
This planet candidate, Alpha Centauri Ab, could be a gas giant, orbiting 1 to 2 times the distance between Sun and Earth, according to two papers to be...
Using the Enhanced Resolution Imager and Spectrograph (ERIS) instrument on ESO’s Very Large Telescope (VLT), two teams of astronomers have detected a...
The radius of a planet is a fundamental parameter that probes its composition and habitability. Precise radius measurements are typically derived from...
The hot-Jupiter exoplanet HIP 67522b orbits its parent star, HIP 67522, so tightly that it appears to cause frequent flares from the star’s surface,...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have detected silicate clouds in the atmosphere of the exoplanet YSES-1c and a circumplanetary...
