A team of international researchers has made a major discovery about aurora activity on Jupiter. Their study supports the previously controversial idea that Jupiter's polar cap is threaded in part with closed magnetic field lines and proves the lights hold clues…
The InSight lander has registered two strong, clear quakes with magnitudes 3.3 and 3.1 in Cerberus Fossae on Mars– the same location where two other powerful tremors with magnitudes 3.6 and 3.5 were detected earlier in the mission. The mission has recorded more…
Based on images of Mars taken during 6 nights in October and November 2020 with the 1-meter telescope at the Pic du Midi Observatory in the French Pyrenees, astronomers led by Francois Colas built a complete planisphere of Mars and generated hundreds of images to…
Since first spotted by NASA's Juno space probe in 2019, a collection of swirling storms arranged in an unusually geometric pattern has been a mystery to most scientists. A new study may have uncovered how the strange weather forms and why the storms behave…
A new study by researchers from Arizona State University (ASU) suggests that the early Moon may have been more volatile-rich than previously believed. Previous studies concluded that lunar volcanoes had exploded primarily cold bedrock, but the ASU team said there…
New images from NASA's MAVEN spacecraft reveal wide areas of Mars' night sky pulsing in ultraviolet light. While researchers understand the light's source, its mysterious spiral shape left them puzzled. "There is a vast spiral of ultraviolet light…
The Visual Monitoring Camera (VMC) attached to Mars Express captured a mysteriously long, thin cloud over the 20 km (12 miles) high Arsia Mons volcano on July 17 and 19, 2020. According to ESA, the cloud is a recurrent feature made up of water ice and is influenced…
NASA's Juno Jupiter probe has captured the first images of the north pole of Ganymede– the largest moon in the solar system and the only moon with its own magnetic field. During a close flyby of Jupiter in December 2019, Juno mapped the north polar regions of…
A new study suggests that the Moon is much younger than what was previously thought– about 85 million years younger. Lunar rock samples collected on the Apollo missions are not old enough to confirm the normally accepted 4.51 billion-year for the Moon's age,…
Astronomers have discovered the absence of a massive unstable star in the Kinman Dwarf galaxy using ESO's Very Large Telescope (VLT). One explanation offered is the end of a luminous blue variable (LBV) eruption of a surviving star, with a mild drop in…
