Scientists have found that Earth's metallic core is not isolated from the mantle and has leaked hydrogen for billions of years, explaining ancient lava compositions.

Earth's magnetic field over the South Atlantic is rapidly weakening, creating risks for satellites and orbital spacecraft due to increased radiation.

On the night of September 17, 2026, an imperceptible earthquake was recorded in Sambir District of Lviv Oblast — the fourth in Ukraine since the beginning of the month, the MCSC reports.

Using deep learning, scientists analyzed more than 2 million seismic records from 1990–2024 and discovered six anomalous bands at Earth's core–mantle boundary, at a depth of 2,900 km. The results were published in Journal of Geophysical Research: Solid Earth.

Geophysicists have recorded the birth of new oceanic crust in real time for the first time in history! 🌊🌋 French scientists, using an autonomous observatory in the Indian Ocean, tracked how the emptying of a magma reservoir led to the subsidence of the floor by 4.2 meters. This is direct proof of spreading, which forms two-thirds of the Earth's surface. 🌍🔬

Scientists have recorded the birth of new oceanic crust in real-time for the first time in history! On the Southeast Indian Ridge, the seafloor split by more than 2 meters, releasing stress accumulated over 60 years. 🌊🌋🌍
