Consistent Asteroid Collisions Rock Previous Thinking on Mars Impact Craters
New research has confirmed the frequency of asteroid collisions that formed impact craters on Mars has been consistent over the past 600 million years. Researchers…

A simulation of the evolution of the Earth’s interior over time, showing the thermal (bottom), chemical (middle), and thermochemical evolution under the simulated conditions. The…
Earthquakes of similar magnitude can cause tsunamis of greatly varying sizes. This commonly observed, but not well-understood phenomenon has hindered reliable warnings of local tsunamis….
Our world’s surface is a jumble of jostling tectonic plates, with new ones emerging as others are pulled under. The ongoing cycle keeps our continents…
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…
Seamounts offer clue to solving a tectonic puzzle. The Hikurangi Margin, located off the east coast of the North Island of New Zealand, is where…
This threatens with sudden destruction of coastal cities and numerous human casualties. An international team of scientists from 20 countries identified 47 problems that hinder…
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…
