A team of astronomers in Japan has detected a thin atmosphere around (612533) 2002 XV93, a trans-Neptunian object about 500 km in diameter — an object...
Using data from NASA’s Juno spacecraft, planetary scientists have produced the most precise measurements of Jupiter’s size in half a century and found...
Using the NASA/ESA/CSA James Webb Space Telescope, astronomers have detected water-ice clouds swirling through the atmosphere of Epsilon Indi Ab, a cold...
New Webb observations of two exoplanets TRAPPIST-1b and TRAPPIST-1c show blistering days and frozen nights, offering the first detailed climate maps of...
A new statistical analysis of archival sky surveys from the early Cold War has found that mysterious, short-lived bursts of light in the night sky were...
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...
Long thought to be fueled by increased atmospheric oxygen concentration, enormous griffinflies from the Carboniferous period, 300 million years ago, may...
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...
New observations of L 98-59d, a member of the five-planet system L 98-59, suggest it harbors a vast global magma ocean that traps sulfur deep inside, forming...
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...
For the first time, astronomers have mapped the vertical structure of Uranus’ ionosphere, uncovering unexpected temperature peaks, weakened ion densities,...
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...
Using high-precision radio-occultation measurements from NASA’s Juno mission and incorporating the effects of zonal winds, planetary scientists derived...
Mars almost certainly once held abundant water. Until now, observations have shown that most atmospheric water loss occurs during the Red Planet’s southern...
New high-resolution observations by ESA’s Solar Orbiter mission show that solar flares are driven by cascading magnetic reconnection events, unleashing...
New research challenges conventional wisdom by demonstrating that mid-ocean ridges and continental rifts, not volcanic eruptions, played the central role...
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...
