Earth Science • Geomagnetism • Deep Earth Tiny crystals formed during enormous volcanic eruptions in ancient China have preserved a remarkable record of Earth’s magnetic field. New research shows that the planet’s magnetic dipole weakened to roughly half its modern strength about 260 million years ago — yet Earth’s magnetosphere apparently remained strong enough to […]

Astronomy • Venus • Moon • September 14, 2026 On September 14, 2026, the crescent Moon will pass directly in front of Venus, temporarily making the brilliant planet disappear from the daytime sky. The lunar occultation of Venus will be visible from parts of Europe, Africa, Asia and western Russia — including Central Europe. Illustration: […]

Giant Sequoias • Yosemite • Hidden Water • New Research Giant sequoias can use more than 2,000 litres of water per day during California’s long dry summers. New subsurface imaging beneath Yosemite’s Mariposa Grove suggests that trees growing on dry hillsides and ridges may survive by accessing water stored more than 2 metres deep inside […]

Earthquakes • Deep Earth • Mantle Plumes • New Research New seismic images beneath Hainan Island, China reveal a hidden system linking deep mantle activity, volcanic rocks and the fault zone of the devastating 1605 Qiongbei M7.5 earthquake. Researchers think volatile-rich fluids rising from depth may have progressively weakened the crust until a major rupture […]

Iceland • Volcanoes • Ground Fractures • New Research Magnetic surveys flown over Grindavík during Iceland’s ongoing volcano-tectonic crisis revealed large fractures and underground cavities hiding beneath apparently intact ground. Some were later excavated — confirming that dangerous cracks could exist with little or no visible warning at the surface. Illustration: Magnetic drone surveys over […]

Volcanoes • Iceland • Fissure Eruptions • New Research Why does a long underground crack filled with magma erupt violently in one place — yet fail to reach the surface just a few kilometres away? New research from Iceland’s giant Laki and Eldgjá fissure eruptions suggests that part of the answer may be sitting directly […]

Ocean Geology • Methane Hydrates • Gulf of Mexico Scientists mapped 70 seismic indicators of methane-hydrate stability beneath the northern Gulf of Mexico. Instead of following the neat pattern expected from pressure and temperature, the inferred boundaries wander by hundreds of meters — and researchers still cannot fully explain why. Conceptual cross-section of methane-hydrate stability […]

It happens to almost anyone. Get caught up in a storm on a Thursday a couple of times and you start half-believing that the weather knows what day of the week it is today. While this obviously doesn’t fit any meteorological finding known to man, it can feel really convincing. If it happens again after […]

New Zealand • Earthquakes • Subduction Zones • New Research A new high-resolution 3D model of New Zealand’s Hikurangi megathrust reveals a striking contrast beneath the North Island: the southern part of the fault is relatively smooth and strongly locked, while the rougher northern section repeatedly releases stress through slow-slip events. Buried chains of ancient […]

Greenland • Glaciers • Ocean Life • New Research Scientists sent an underwater robot into one of the most dangerous and poorly observed environments on Earth: the submerged edge of a glacier in South Greenland. Instead of finding a biological wasteland of cold, dark and sediment-choked water, the cameras encountered large aggregations of krill, fish, […]
