Eggshell Planets Have a Thin Brittle Crust With No Tectonics – Unlikely To Be Habitable
Planets without plate tectonics are unlikely to be habitable. But currently, we’ve never seen the surface of an exoplanet to determine if plate tectonics are…

Strange ‘eggshell planets’ are among the rich variety of exoplanets possible, according to a study from Washington University in St. Louis. These rocky worlds have…
Washington Irving’s classic tale about a headless horseman plays out an ancient landscape scarred by tectonic collisions and the relentless forces of erosion. In 1798,…
Multidisciplinary team of materials physicists and geophysicists combine theoretical predictions, simulations, and seismic tomography to find spin transition in the Earth’s mantle. The interior of…
Assistant professors Camilla Cattania and William Frank discuss the science behind the 2010 and 2021 earthquakes in Haiti. On August 14, 2021, a magnitude 7.2…
One of Earth’s unique features is that it has continents. Contrary to many theories, the continents have always been rich in silica (which is found…
A new study led by the University of Colorado Boulder reveals the complex history behind one of the Grand Canyon’s most well-known geologic features: A…
Scientists from Cambridge University and NTU Singapore have found that slow-motion collisions of tectonic plates drag more carbon into Earth’s interior than previously thought. They…

Indonesia’s volcanoes are among the world’s most dangerous. Why? Through chemical analyses of tiny minerals in lava from Bali and Java, researchers from Uppsala University…
The surface of Venus is cracked and moves like ice floating on the ocean – likely due to tectonic activity. The big idea Much of…
A new analysis of Venus’ surface shows evidence of tectonic motion in the form of crustal blocks that have jostled against each other like broken…
Research team led by the University of Göttingen discovers crater floor sagging from bowl-shaped volcanic ash layer. The almost 15-million-year-old Nördlinger Ries is an asteroid…
Researchers find that a large earthquake could set off eruption of Hawaii’s Mauna Loa volcano. Scientists from the University of Miami (UM) Rosenstiel School of…
In a newly published paper, Virginia Tech geoscientists have found that shallow wastewater injection – not deep wastewater injections – can drive widespread deep earthquake…
