Models of the flood that refilled the Mediterranean put its peak flow through Gibraltar at roughly 100 million cubic metres a second — around 1,000 times the Amazon's average discharge — with erosion at the Camarinal Sill reaching roughly 0.4 metres a day
6+ hour, 26+ min ago (105+ words) When an ancient sea vanished, its return was so catastrophic that it reshaped geology itself—yet scientists still debate exactly how violent the deluge truly was....
Earth’s outer core is an ocean of liquid metal whose volume roughly equals that of Mars. Seismic waves from repeated French nuclear tests at Mururoa have now revealed parts of it changing over only a few years: signals arrived up to 0.2 seconds early or late, suggesting that structures hundreds of kilometres wide are moving through the molten core on human timescales.
1+ day, 19+ hour ago (844+ words) Closely matched seismic paths from Mururoa tests changed by up to 0.2 seconds between 1977 and 1995, revealing rapid outer-core variation while leaving the responsible material open to interpretation....
Jupiter pulls so hard on Io that the moon’s solid ground rises and falls by as much as 100 metres every orbit — a tide in rock the height of a 30-storey building, and the repeated flexing powers the most volcanically active world in the Solar System
3+ day, 22+ hour ago (1555+ words) Io's ground can move by as much as 100 metres as Jupiter's changing tide flexes the moon, converting orbital energy into the heat that drives its volcanoes. By Lachlan Brown · Edited by Lachlan Brown Published August 21, 2026 · How we edit Io looks…...
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
4+ day, 2+ hour 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....
The US Navy once sent aquanauts to live on the ocean floor for weeks, hoping SEALAB would prove humans could colonise the deep. Instead, one diver died, the program collapsed, and the underwater future quietly disappeared
6+ day, 20+ hour ago (551+ words) What began as humanity's bold dream to conquer the ocean's depths became a cautionary tale about the limits of ambition and the price of pushing too far too fast. Published August 18, 2026 · How we edit Carpenter was the second American to…...
Earth has had eight continents all along — the one missing from every map and school textbook is nearly twice the size of India, 94 percent underwater, and has been quietly sitting beneath the South Pacific for 85 million years
1+ week, 5+ day ago (108+ words) Zealandia is a coherent 4.9-million-square-kilometre body of continental crust, about 94 per cent submerged. Its classification depends on geology beneath the coastline, not a newly discovered landmass....
A rock blasted off Mars is not a comet and is only a meteor for seconds; in space it is a meteoroid, and on the ground it becomes a Martian meteorite
1+ week, 6+ day ago (508+ words) The same Martian rock transforms into four different things before scientists can even study it....
Mars can snow carbon dioxide at its poles, while some of its warmest summer landscapes grow dry-ice frost overnight that vanishes back into gas after sunrise
1+ week, 6+ day ago (583+ words) Mars can produce snow from carbon dioxide near its winter poles. Far from those seasonal caps, however, the same material can appear in a quieter and more...
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+ week, 6+ 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....
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
2+ week, 8+ hour 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…...
