Early Mars had rivers, but the cause of the transition from a wet planet to dry remains unknown. Past Martian climate can be probed using the distribution...
By December 2022, NASA expects its InSight (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) lander to have become inoperative,...
Using neutron and X-ray tomography, a team of planetary researchers from Lund University and elsewhere examined a section of Miller Range (MIL) 03346,...
GOES-18 (also known as GOES-T) is a new next-generation weather satellite of the National Oceanic and Atmospheric Administration (NOAA).
This image, taken...
In the 2000s, planetary researchers spotted ghostly, blue-white morning frost on the Martian surface in visible light images from NASA’s Mars Odyssey...
A new image from ESA’s Mars Express shows a network of long grooves and scratches in Tantalus Fossae, a large fault system in the Arcadia quadrangle...
In a new paper in the Astrophysical Journal, a duo of astronomers from the Kavli Institute for Particle Astrophysics and Cosmology at Stanford University...
On April 19, 2022, NASA’s Ingenuity helicopter recently surveyed both the parachute that helped the Perseverance rover land on Mars and the cone-shaped...
Using state-of-the-art analytical techniques, researchers have detected diverse suites of nucleobases — including canonical base pairs (e.g., adenine-uracil,...
The nature of Earth’s earliest crust and crustal processes remains enigmatic due to the almost complete lack of a rock record older than 4 billion years...
The gravity of a large object in space can keep a smaller object from spinning, a phenomenon called tidal locking. The discovery and characterization of...
Using data from ESO’s Very Large Telescope (VLT), NASA’s Spitzer Space Telescope, the Subaru Telescope, the Keck Telescope, the Gemini South and North...
Using seismic data from NASA’s Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight) lander, planetary researchers...
Using the Subaru Telescope and the NASA/ESA Hubble Space Telescope, astronomers have found evidence for a Jupiter-like protoplanet around the young star...
The atmosphere of Jupiter is enriched with heavy elements by a factor of about 3 compared to a protosolar composition. The origin of this enrichment and...
NASA’s Perseverance rover first recorded Martian sounds on February 19, 2021, the day after its arrival. These sounds fall within the human audible spectrum,...
Utopia Planitia, a large lava plain in the northern hemisphere of Mars, has a diameter of roughly 3,300 km (2,051 miles) — just under twice the north-south...
