An artist’s concept from 1969 depicts a lunar module descending to the Moon’s surface. Because of the Moon’s very thin atmosphere, the exhaust expands significantly…
An artist’s impression of Mars’ inner structure. The topmost layer is the crust, and beneath it is the mantle, which rests on a solid inner…

Locations of the 268 global seismic stations that were analyzed in the research. Lockdown effects are observed (red) at 185 out of 268 stations. Symbol…
The ancient philosopher Plato conjectured that the universe was composed of particular geometric shapes; the earth, of cubes. Findings from a multidisciplinary research team found…
A new study by the University of Leeds and University of California at San Diego reveals that changes in the direction of the Earth’s magnetic…
Physicists Explain Why Changes to Earth’s Magnetic Field Are Weaker Over the Pacific A new study by University of Alberta physicists provides an explanation for…
Scientists examined hundreds of samples taken along the global ridges that contain recycled ancient oceanic crust in variable amounts. “Depleted” segments of the ridge received…
Extensional faults (arrows) on the surface of Pluto indicate expansion of the dwarf planet’s icy crust, attributed to freezing of a subsurface ocean. Credit: NASA/Johns…

University of Texas at Dallas geoscientists used earthquake data and a computationally intensive technique called a full waveform inversion to create 3D images of the…
How’s the weather on Mars? Tough on rovers, but very good for generating and moving highly reactive chlorine compounds. New research from Washington University in…
Skoltech scientists and their industry colleagues have found a way to use machine learning to accurately predict rock thermal conductivity. Credit: Pavel Odinev / Skoltech…
Earthquakes send sound waves through the Earth. Seismograms record the echoes as those waves travel along the core-mantle boundary, diffracting and bending around dense rock…

The crystal structure of the feldspar anorthite under normal conditions (left) and the newly discovered high-pressure variant (right). Under normal conditions, the silicon and aluminum…
[embedded content]Earthquakes that occur more than 300 kilometers below the Earth are poorly understood. UC Davis geophysicist Magali Billen modeled stresses in a sinking tectonic…
The magnetic field is thought to be largely generated by an ocean of superheated, swirling liquid iron that makes up Earth’s the outer core 3000…
