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,...
Alongside Earth and Mars, Titan is the third planetary body in the Solar System to show evidence for widespread and diverse sedimentary environments, including...
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...
Surface landforms called double ridges occur across every sector of Jupiter’s icy moon Europa and can be hundreds of kilometers in length. In new research,...
Jupiter’s moon Io is the most volcanically active body in the Solar System, and the body that is known to be most rapidly resurfaced. Surface modification...
The estimated diameter of the nucleus of comet C/2014 UN271 (Bernardinelli-Bernstein) is approximately 137 km (85 miles) across, making it the largest...
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...
An ancient impact that formed the South Pole-Aitken basin, a vast impact structure on the far side of the Moon, would have created a massive plume of heat...
Using seismic data from NASA’s Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight) lander, planetary researchers...
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...
The significantly weaker magnetic field, smaller magnetosphere, and much faster timescale of processes around Mercury, when compared with Earth, enable...
The discovery probability of long-period comets passing near the Sun is highest during their first passage and then declines, or fades, during subsequent...
Cryovolcanoes (ice volcanoes) are similar to normal volcanoes but instead of being formed from molten rock, they are made by frozen liquids like ammonia...
Each year, about 2 kg of helium-3, a rare isotope of helium gas, escapes from Earth’s interior, mostly along the mid-ocean ridge system. Helium-3 is...
