Previous research estimated that it took hundreds of million years for early Earth’s magma ocean to solidify, but new research narrows these large uncertainties...
Earth has a hot core that heats the surrounding mantle, which carries that heat up to the planet’s lithosphere. The heat is then lost to space, cooling...
Astronomers using NASA’s Infrared Telescope Facility (IRTF) telescope at Mauna Kea Observatory have captured and analyzed visible and near-infrared reflectance...
Frictional electrification is a common process in the Solar System, with Martian dust activities known to be a powerful source of electrical charge buildup....
Dr. Lokesh Mishra and his colleagues from the University of Bern and Geneva Observatory propose that the space of planetary system architectures be partitioned...
Saturn is known for its iconic, pristine rings. However, the main B ring can have splotches and streaks of darker or lighter material, known as spokes,...
The newly-detected molten rock layer is located about 150 km (93 miles) from the surface of our planet and is part of the asthenosphere, which sits under...
A small near-Earth asteroid designated 2023 BU made its closest approach on January 26, 2023 at 7:29 p.m. EST (4:29 p.m. PST, or January 27, 2023 at 00:29...
The rotation of the Earth’s inner core may have recently paused and could be reversing, according to new research by geoscientists from Peking University.

An international team of researchers has detected abundant polyaromatic compounds, organic magnesium compounds, aliphatic branched carboxylic acids, aldehydes,...
Using data from NSF’s Karl G. Jansky Very Large Array (VLA), the Atacama Large Millimeter/submillimeter Array (ALMA) and NASA’s Juno spacecraft, two...
A new image from the High Resolution Stereo Camera (HRSC) on board ESA’s Mars Express orbiter shows an exciting landscape of layered deposits, frost,...
Elysium Planitia, a flat-smooth plain just north of the Martian equator, is underlain by an 4,000-km-diameter active mantle plume, according to new research...
The Chicxulub-like asteroid crash landed in shallow ocean waters in the Martian region of Chryse Planitia 3.4 billion years ago (Hesperian period) and...
An analysis of chromium isotopes in Martian meteorites suggests that approximately 4.5 billion years ago, there was enough water for the entire planet...
Using images obtained by two orbiting spacecraft, NASA’s Mars Reconnaissance Orbiter and ESA’s Mars Express, planetary researchers analyzed textured...
Stromatolites are solid, laminar structures reflecting complex interplays between microbial communities and their environment.
