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...
University of Washington researcher Baptiste Journaux and colleagues believe the newly-created substances could form at the surface and bottom of deep...
Frictional electrification is a common process in the Solar System, with Martian dust activities known to be a powerful source of electrical charge buildup....
Stunning radar images of the near-Earth asteroid 2011 AG5 were obtained from January 29 to February 4, 2022, by the powerful 70-m (230-foot) Goldstone...
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,...
When ocean-bearing moons begin to cool down, their oceans can freeze. As new ice accretes to the bottom of the existing ice shell, the added volume of...
The newly-discovered asteroid is less than 230 m (755 feet) across, and orbits within the main asteroid belt, which is located between Mars and Jupiter.
An...
Mimas, a small moon of Saturn, is heavily cratered and lacks the typical characteristics of an ocean-bearing moon, such as the active surface of Enceladus....
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have captured the reflectance spectrum of the double-ringed centaur 10199 Chariklo and observed...
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...
An international team of researchers has detected abundant polyaromatic compounds, organic magnesium compounds, aliphatic branched carboxylic acids, aldehydes,...
In new research, paleontologists analyzed abundances of sunscreen-like chemicals in 800 fossil pollen grains from 250-million-year-old rocks in Tibet.
The...
Enceladus, the sixth-biggest moon of Saturn, is a top candidate in the search for extraterrestrial life in the Solar System.
An artist’s impression of...
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...
The El Ali meteorite, a 15.2-ton iron meteorite found in 2020 near the tiny town of El Ali in Somalia, contains at least two new minerals: elaliite and...
