Parts of Earth's magnetic field work in reverse compared to what long-standing models predict, new research suggests.
A European Mars orbiter spotted barcode-like dust streaks on the slopes of Apollinaris Mons, revealing how tiny avalanches help drive the Red Planet's massive dust cycle.
New lab experiments suggest that water may not be a rare visitor delivered by chance but rather a fundamental ingredient woven into the process of planetary birth.
"Solar Orbiter can now provide this missing piece of the puzzle."
NASA's first dual-satellite mission to another planet, ESCAPADE, will study Mars' magnetic field and atmosphere in 3D to uncover how it lost its water and air.
"This discovery ends a protracted search for these waves that has its origins in the 1940s."
Two new climate reports warn Earth's vital signs are flashing red after the hottest year in 125,000 years, but say recovery is still possible with swift action.
New research shows how Jupiter carved out rings and gaps that changed how and when planets and meteorites formed.
The century-old mystery of dark matter — the invisible glue thought to hold galaxies together — just got a modern clue.
Ancient rocks from Greenland, Canada and Hawaii preserve a rare chemical fingerprint that may come from the Earth before the moon-forming impact, a new study reports.
A new study suggests dark matter could subtly tint or polarize light, leaving faint color clues that next-generation telescopes might detect.
From how space rocks wobble to where to hit them, scientists are learning the fine art of asteroid deflection — and it could one day save Earth.
After decades of searching, astronomers have imaged two supermassive black holes in orbit around each other at the heart of quasar OJ287.
Scientists have spotted the first clear sign of water from an interstellar comet, 3I/ATLAS, offering new clues to the chemistry of other planetary systems.
Two decades of spacecraft images reveal more than 1,000 dust devils whipping across Mars at unexpected speeds, offering fresh insight into how wind and dust shape the Red Planet.
Astronomers using JWST have captured the clearest view yet of a doomed red supergiant star just before it exploded, solving a decades-old mystery about why such stars rarely appear to go supernova.
NASA's Perseverance rover has found minerals that could have powered life on Mars — or simply shaped the Red Planet's environment in fascinating ways.
Astronomers using JWST have captured the sharpest infrared view yet of the supermassive black hole jet in M87, offering new insights into its structure and physics.
Scientists believe a moon of Uranus may have once had a subsurface ocean.
Astronomers using the James Webb Space Telescope have delivered the first detailed weather report of a nearby rogue world, and it's stormier than expected.
Scientists have confirmed that the Silverpit Crater in the North Sea was caused by an asteroid impact over 40 million years ago, ending years of controversy over its origin.
New JWST observations show Saturn's auroras dotted with dark beads and a star pattern missing two arms, puzzling astronomers.
New simulations suggest sub-Neptune planets may be drier than thought, challenging the "water world" hypothesis and reshaping the search for life beyond Earth.
Fresh analysis of Perseverance rover data reveals Jezero Crater experienced repeated episodes of water activity, strengthening the case for habitability and raising the stakes for Mars Sample Return.
