For the first time, astronomers have mapped the vertical structure of Uranus’ ionosphere, uncovering unexpected temperature peaks, weakened ion densities,...
Planetary scientists have identified thousands of small mare ridges (SMRs) across the Moon’s maria, pointing to active tectonic forces that may shape...
In a paper to be published in the Planetary Science Journal, scientists from SETI Institute, Southwest Research Institute, Caltech and the Observatoire...
New orbital data reveal that the most recently active volcanic systems on Mars weren’t simple one-off blasts into space; instead, long-lived magmatic...
A new analysis of exquisitely preserved laminated rocks (varves) from the Port Askaig Formation on the Garvellach Islands, Scotland, shows that climate...
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 archival radar data from NASA’s Magellan spacecraft, planetary researchers have identified a vast underground conduit beneath the surface in the...
Known non-biological sources, from meteorites to surface chemistry, fall short of accounting for organic compounds detected by NASA’s Curiosity rover,...
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...
Two immense, ultrahot rock structures located at the base of Earth’s mantle, around 2,900 km beneath Africa and the Pacific, have been shaping Earth’s...
A new analysis of archival data from the Near Infrared Mapping Spectrometer (NIMS) on board NASA’s Galileo spacecraft has revealed the first evidence...
On January 22, 2026, the NASA/ESA Hubble Space Telescope observed the interstellar comet 3I/ATLAS nearly perfectly aligned with the Sun-Earth axis, revealing...
Planetary scientists analyzing oxygen isotopes in lunar soil from the Apollo mission sites conclude that meteorite bombardment over 4 billion years could...
A duo of geophysicists from Washington State University and Virginia Tech has uncovered a plausible pathway for nutrient transfer from the radiation-charged...
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...
