New study finds lunar swirls linked to topography

Every lunar swirl identified to date coincides with a magnetic field over the lunar surface, which scientists think deflects solar particles. There also seems to be a connection between lunar swirls and lava tubes buried beneath them.

A green glow in the martian night

When future astronauts explore Mars's polar regions, they will see a green glow lighting up the night sky. For the first time, a visible nightglow has been detected in the martian atmosphere by ESA's ExoMars mission.

Oxygen directly detected in Venus clouds

Researchers have made the first direct detection of atomic oxygen in the atmosphere of Venus. Some say it builds the case the planet was more hospitable in the past.

Saturn's Ocean Moon Enceladus Has All The Building Blocks For Life

Most of what we know about Enceladus and its ice-covered ocean comes from the Cassini mission. New research based on Cassini data strengthens the idea that Enceladus has the chemicals necessary for life.

Uranus aurora discovery offers clues to habitable icy worlds

Astronomers confirm the existence of an infrared (IR) aurora on Uranus. This could help astronomers identify exoplanets that might support life, a large number of which are icy worlds.

Quakes on Mars Reveal We Were Wrong About Its Core

Two new papers show a 150 kilometer-thick layer of molten silicate rock at the base of the mantle envelopes Mars' liquid iron-alloy core.

Venus' ancient Earth-like plate tectonics

A recent study suggests that Venus, typically viewed as a fiery wasteland, may have experienced Earth-like plate tectonics in its distant past.

Webb pinpoints a high-speed jet stream on Jupiter

Researchers using the NASA/ESA/CSA James Webb Space Telescope's NIRCam (Near-Infrared Camera) have discovered a high-speed jet stream sitting over Jupiter's equator, above the main cloud decks.

The moon is 40 million years older than thought

Crystals brought back from the Moon by Apollo astronauts in 1972 push back the age of the moon by 40 million years, to at least 4.46 billion years old. 

Mysterious 'Singing' Plasma Waves Detected Around Mercury

So-called chorus waves have been recorded at Earth, and Jupiter, and Saturn; and observed at Uranus and Neptune. Now, international scientists have detected them whistling around Mercury.

Distant Objects Show Solar System Extends Further Than We Knew

A new method for scanning telescope images for the faintest signs of rock far beyond Pluto has uncovered evidence that our Solar System's disc of material extends far further into interstellar space than we thought.

Kuiper Belt Object Arrokoth's Large Mounds Have Common Origin

Among the most striking geologic features on the surface of Arrokoth is the ensemble of large, broadly similarly sized mound-like features seen on the larger lobe.

Perseverance Captures a Beautifully Strange 'Blue Sunset' on Mars

Sunlight on Mars interacts with iron-rich dust that hangs in the atmosphere. This ultimately scatters lower-frequency red light through the sky during the day. At twilight, however, the red light is filtered away and the sky glows a cool blue.

Scientists Confirm What's Inside The Moon

Resent studies question the evolution of the Moon magnetic field thanks to its demonstration of the existence of the inner core.

Largest ever solar storm identified in a 14,300-year-old tree rings

A similar solar storm today would be catastrophic for modern technological society—potentially wiping out telecommunications and satellite systems, causing massive electricity grid blackouts, and costing us billions of pounds.
