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...
Researchers have found ancient gases and fluids trapped in 1.4-billion-year-old halite crystals from northern Ontario, Canada. Their analyses directly...
PSR J2322-2650b, an enigmatic Jupiter-mass exoplanet orbiting the millisecond pulsar PSR J2322-2650, appears to have an exotic helium-and-carbon-dominated...
The new observations with the NASA/ESA/CSA James Webb Space Telescope suggest that TOI-561b is surrounded by a thick blanket of gases above a global magma...
In 1986, NASA’s Voyager 2 provided the only direct measurement of the radiation environment at Uranus. These findings established the well-accepted characterization...
Using high-precision spectroscopic observations from the Near Infrared Imager and Slitless Spectrograph (NIRISS) onboard the NASA/ESA/CSA James Webb Space...
Using data captured by the SuperCam microphone aboard NASA’s Perseverance rover over two Martian years, planetrary scientists have detected 55 triboelectric...
Scientists from University of Sydney and start-up Dewpoint Innovations have created a porous polymer coating that reflects up to 97% of sunlight and radiates...
Researchers have discovered 6-million-year-old-ice and air in shallow ice cores drilled in the Allan Hills region of East Antarctica. They speculate that...
The new map of WASP-18b, a hot-Jupiter exoplanet located approximately 325 light-years from Earth, reveals an atmosphere with distinct temperature zones...
