Tiny quantum sensors watch materials transform under pressure
Since their invention more than 60 years ago, diamond anvil cells have made it possible for scientists to recreate extreme phenomena—such as the crushing pressures deep inside the Earth’s mantle—or to enable chemical reactions that can only be triggered by intense pressure, all within the confines of a laboratory apparatus that you can safely hold in the palm of your hand….
Olivine-norite rock detected by Yutu-2 likely crystallized from the SPA impact melt pool
The South Pole-Aitken (SPA) is the largest and deepest basin on the Moon, theoretically opening a window into the lunar lower crust and likely into the upper mantle. However, compositional information of the SPA basin was mainly obtained from orbital remote sensing. Chang’E-4 landed in the SPA Basin, providing a unique chance for in situ probing the composition of the lunar…
Why Nile hasn’t changed course in 30 million years
Scientists say they’ve solved the geologic mystery of the Nile River’s unchanging path, and also discovered the river is about 30 million years old – 6 times older than previously believed. Source: https://earthsky.org/earth/why-nile-river-hasnt-changed-course-age…
Nile River Formed Millions of Years Earlier Than Thought, Study Suggests
