In a new study, a team of astronomers from Penn State and NASA’s Jet Propulsion Laboratory analyzed when and where human deep space transmissions would...
On July 20 and July 23, 2025, NASA’s Psyche spacecraft looked back toward home and captured images of Earth and our Moon from about 290 million km (180...
Using data from NASA’s Juno spacecraft, planetary researchers have detected a new type of plasma wave in the auroral zones above Jupiter’s north pole.
This...
On July 24, 2025, the 4,608th Martian day, or Sol, of the mission, NASA’s Curiosity rover imaged wind-eroded rocks shaped like a piece of coral in the...
Radiolysis induced by Galactic cosmic rays could provide a viable energy source for microbial metabolism in the subsurface environments of rocky planetary...
Uranus releases about 15% more energy than it receives from the Sun, according to two new papers published in the journal Monthly Notices of the Royal...
Discovered by the Large inclination Distant Objects (LiDO) survey and designated 2020 VN40, this trans-Neptunian object is the first confirmed body that...
The radius of a planet is a fundamental parameter that probes its composition and habitability. Precise radius measurements are typically derived from...
Planetary scientists have discovered more than 15,000 km of ancient riverbeds in Noachis Terra, a region in Mars’ southern highlands. This discovery...
The Martian meteorite Northwest Africa (NWA) 16254 is a 406-g gabbroic shergottite found two years ago in Algeria.
Image of the entire NWA 16254 sample...
During periods known as Snowball Earth, between 720 and 635 million years ago, early eukaryotes — complex cellular lifeforms that eventually evolved...
In their new paper, Los Alamos National Laboratory planetary scientist Nina Lanza and colleagues looked at what would be needed to make the surface environment...
In new research, astronomers using the NASA/ESA Hubble Space Telescope searched for signs of interactions between the magnetic environment and the surfaces...
Slope streaks are dark features on Martian slopes that form spontaneously and fade over years to decades. Some planetary scientists have interpreted those...
Mars hosts various auroral processes despite the planet’s tenuous atmosphere and lack of a global magnetic field. To date, all aurora observations have...
The Jovian aurorae are hundreds of times brighter than those seen on Earth, says a team of astronomers by University of Leicester’s Dr. Jonathan Nichols.
These...
Planetary scientists expected the outermost layer of the crust of Earth’s hotter twin would grow thicker and thicker over time given its apparent lack...
