New images from the NASA/ESA/CSA James Webb Space Telescope show the ice giant Uranus, its faint rings and several moons.
This image of Uranus, captured...
The most feasible explanation is that icy ring particles raining down onto Saturn’s atmosphere cause this heating, according to a team of astronomers...
There are many thousands of volcanoes on the surface of Venus. These volcanoes provide clues into the interior properties of the planet, properties that...
Neptunian Trojans are trans-Neptunian objects in 1:1 mean-motion resonance with the ice giant Neptune. These asteroids are generally thought to have been...
Scientists from China and the United States have analyzed the impact glass beads from a lunar soil sample returned by China’s Chang’e-5 mission.
Asteroid...
The radar properties of icy satellites of Jupiter and Saturn commonly differ by more than an order of magnitude from those of rocky planets because of...
The previously unreconciled acceleration of 1I/2017 U1 ‘Oumuamua, a strange object of extrasolar origin discovered on October 19, 2017 by the Pan-STARRS...
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...
