Ichthyosaur

Nevada home to 246M-year-old fossil of pregnant ichthyosaur

El Niño events and high-latitude Eurasian warming are usually observed after large tropical eruptions. However, simulations of climate impacts by volcanos show large biases when compared with observations, calling for substantial improvements in climate models. The graph depicts the change in zonally averaged surface temperature in observations (the shaded part) and simulations (the line) after large tropical volcanic eruptions. The equation denotes the chemical reaction in the stratosphere. Credit: Advances in Atmospheric Sciences

The deep origin of craters and mounds was discovered using cutting edge 3D seismic technology which can penetrate deep into the ocean floor, and help scientists visualize the structures in the hard bedrock underneath. Illustration: M. Waage

This artist’s impression shows a view of the surface of the planet Proxima b orbiting the red dwarf star Proxima Centauri, the closest star to the Solar System. The double star Alpha Centauri AB also appears in the image to the upper-right of Proxima itself. Proxima b is a little more massive than the Earth and orbits in the habitable zone around Proxima Centauri, where the temperature is suitable for liquid water to exist on its surface.

A schematic diagram of the Earth's deep oxygen factory shows the oxygenation and deoxygenation processes of hydrous mantle materials in the lower mantle across the ~1000 km depth beneath Earth's surface. Under the conditions of Earth's middle mantle, scientists discovered an oxygen-excess phase, (Mg,Fe)2O3+δ (0 < δ < 1) that can be formed with under-saturated water at >1000 kilometers depths. Those oxygen-excess materials may have long-termly oxidized the shallow mantle and the crust, which is essential to allow free oxygen to build up in Earth's atmosphere. Credit: Science China Press

Subduction zones occur where one tectonic plate dives under another. New computer modeling by Magali Billen, professor of earth and planetary sciences at UC Davis, shows why earthquakes on these sinking plates cluster at certain depths and could give insight into processes deep in the Earth.

Researchers developed a technique that allows them to study the atomic arrangements of liquid silicates at the extreme conditions found in the core-mantle boundary. This could lead to a better understanding of the Earth's early molten days, which could even extend to other rocky planets. Credit: Greg Stewart/SLAC National Accelerator Laboratory
