One of the biggest challenges to growing food on Mars is the presence of perchlorate salts, which have been detected in the Martian regolith (soil) and...
Mars has a liquid iron alloy core at its center. Using seismic data gathered by NASA’s InSight lander, planetary scientists have made the first observations...
The aftermaths of supernovae always produce X-rays, but if the supernova’s blast wave strikes dense surrounding gas, it can produce a particularly large...
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...
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...
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...
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...
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...
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...
