An international team of researchers has detected nicotinic acid (also known as vitamin B3 or niacin) and uracil, one of the four nucleobases in ribonucleic...
On September 26, 2022, NASA’s DART spacecraft collided with the asteroid Dimorphos in a controlled test of our asteroid deflection capabilities. The...
A so-called light-toned deposit (LTD) in Eastern Noctis Labyrinthus, about 160 km (99.4 miles) north-west of Oudemans crater near Mars’ equator, presents...
The StarCrete is twice as strong as regular concrete and is made from extraterrestrial dust, potato starch, and a pinch of salt.

In new research, planetary scientists from the University of Maryland and elsewhere analyzed melted meteorites that had been floating around in space since...
Planetary scientists have examined volcanic areas on Venus that were imaged two or three times by NASA’s Magellan spacecraft and identified a 2.2-km2...
The subsurface ocean of Jupiter’s icy moon Europa is heated from below via tidal heating and radioactive decay of the rocky interior, while being cooled...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have detected gaseous water in the planet-forming disk around V883 Orionis, a...
In the lower atmosphere of Earth, oxygen contains a higher fraction of the heavy isotope 18O than ocean water does. This enrichment is a signature of biological...
‘Sun rays’ are also known as crepuscular rays, from the Latin word for twilight. It was the first time sun rays have been so clearly viewed on Mars.
This...
The new model provides a high-resolution understanding of how today’s geophysical landscapes were created and how millions of tons of sediment have flowed...
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...
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,...
