Saturn's moon Mimas looks like a dead, cratered rock — its surface is so inert that scientists assumed it was frozen solid — but in 2024 astronomers confirmed a global ocean hidden beneath the ice, formed just 5 to 15 million years ago
1+ mon, 5+ day ago (696+ words) Mimas looks frozen and geologically quiet, yet Cassini's measurements point to a young global ocean beneath 20 to 30 kilometres of ice. Published August 7, 2026 · How we edit Mimas does not look like an ocean world. It is small, cold and covered in…...
Mars’s vanished northern ocean may have left two independent fingerprints: China’s Zhurong rover detected buried, sloping sand-and-gravel deposits resembling an ancient beach, while University of Arkansas researchers identified nine river deltas bearing the backwater geometry of rivers entering a vast standing body of water.
2+ week, 3+ day ago (1034+ words) Zhurong radar layers and backwater geometry in nine Aeolis Dorsa channel belts provide separate evidence for a large ancient body of water in Mars’s northern lowlands....
A dark rock picked off the gravel plains of Oman turned out to be a piece of Mars, blasted off the planet by an impact. It now rides aboard Perseverance as a calibration target, back on the world it came from
1+ mon, 2+ day ago (467+ words) A meteorite that fell to Earth from Mars now helps calibrate instruments on a rover exploring the Red Planet—a cosmic round trip that took 300,000 years. By Space Daily Editorial Team Published August 11, 2026 · How we edit In 1999, out on the…...
An asteroid struck somewhere north of Australia 11 million years ago, scattering molten glass across a 900-kilometre ellipse in South Australia — yet scientists still cannot find the crater it left behind
2+ mon, 19+ hour ago (419+ words) The glass is small enough to sit in a museum drawer, but the event it points to was not small. A set of unusual Australian tektites, now called ananguites,...
Scientists found a 3.7-billion-year-old chemical fingerprint in Australia’s oldest rocks that lines up with Apollo samples when traced back through time — strengthening evidence that Earth and the Moon were mixed together in a giant ancient impact
1+ week, 1+ day ago (381+ words) A distant lunar sample and Earth's most ancient rocks are telling the same isotopic story—one that only makes sense if a catastrophic collision once scrambled our planet and its future Moon together....
Olympus Mons grew so massive that parts of its lower flanks catastrophically collapsed, sending broken rock sliding hundreds of kilometres across the Martian plains—possibly lubricated when hot lava melted buried ice.
3+ day, 11+ hour ago (718+ words) Orbital evidence links Olympus Mons's aureole to immense flank failures. Water or ice may explain the long runout, but lava-driven melting remains one proposed mechanism....
For years scientists argued whether the pale band along Jezero crater's western inner rim was lakeshore sediment or altered igneous rock. A study published in January 2026 suggests both sides were partly right — one stretch of it looks like a beach
1+ mon, 2+ day ago (573+ words) Mars's most disputed geological feature may finally reveal what it is: a shoreline where ancient water met stone. Published August 10, 2026 · How we edit Look at Jezero crater from orbit and one feature stands out: a pale band along the inside…...
The Moon is rusting even though it has no air and almost no liquid water — and the leading explanation is that oxygen escaping Earth rides our magnetic tail 385,000 kilometres into space during the few days each month when the solar wind is blocked
3+ week, 1+ day ago (687+ words) Chandrayaan-1 found hematite near the lunar poles. Orbital patterns and laboratory tests point to oxygen ions escaping Earth and reaching the Moon through our magnetotail....
A grain of stardust extracted from the Murchison meteorite that landed in Victoria in 1969 was dated to roughly 7 billion years old, meaning it condensed in the atmosphere of a dying star more than 2 billion years before the Sun existed
1+ mon, 2+ day ago (552+ words) A silicon carbide grain extracted from the Murchison meteorite, which fell on a Victorian dairy farm in 1969, was dated in 2020 to about seven billion years old — condensed in the atmosphere of a dying star more than two billion years before…...
A zircon crystal small enough to sit on a fingertip, found in the Jack Hills of Western Australia, has been dated to 4.404 billion years old, right around the same moment a 2025 study says the Moon itself finished crystallizing
1+ mon, 1+ day ago (29+ words) A speck of ancient Earth and our newborn Moon may have formed within moments of each other, upending how scientists understand the young solar system's violent beginning....
