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.

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...
Observations of large valley networks on today’s Mars suggest formation by flowing water. However, most climate models cannot sustain temperatures above...
NASA’s Curiosity rover has found evidence of a carbon cycle on ancient Mars, bringing scientists closer to an answer on whether the planet was ever capable...
Recent measurements from NASA’s InSight mission show that Mars’ core is less dense than planetary scientists previously believed. This indicates that...
The rotation period of Uranus was estimated to be 17.24 hours in 1986 from radio auroral measurements made by NASA’s Voyager 2 spacecraft. Using the...
A Martian dust devil can be seen consuming a smaller one in a series of images taken by a navigation camera aboard NASA’s Perseverance rover.
Dust devils...
Certain lichen species can withstand Mars-like conditions with an X-ray radiation dose of 50 Gy (Grays) that is expected on the Mars surface over one year...
An unexpected phenomenon called convection could help explain many of the volcanoes and other features of the Venusian landscape.
