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...
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 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...
A new analysis of stress, tides and interior forces suggests Jupiter’s icy moon Europa lacks the active seafloor faulting needed for robust hydrothermal...
The data from NASA’s Cassini mission to Saturn initially led researchers to suspect a large underground ocean composed of liquid water on Titan. However,...
The composition of Uranus and Neptune might be less icy than previously thought, according to a new study by University of Zürich scientists.
Uranus could...
Jupiter’s icy moon Europa is an ocean world that is a prime candidate in the search for potential extraterrestrial habitability and life beyond Earth....
In 1986, NASA’s Voyager 2 provided the only direct measurement of the radiation environment at Uranus. These findings established the well-accepted characterization...
NASA’s Perseverance rover has discovered several thousand small, light-toned rock fragments, or float rocks, with some exhibiting spectral signatures...
Using data captured by the SuperCam microphone aboard NASA’s Perseverance rover over two Martian years, planetrary scientists have detected 55 triboelectric...
For decades, scientists have been baffled by two enormous structures buried deep inside Earth. These anomalies may retain geochemical signatures distinct...
