Using high-resolution images from NASA’s Mars Reconnaissance Orbiter, planetary scientists have discovered 4-billion-year-old layered deposits containing...
In 2020, planetary scientists detected small amounts of the biosignature gas phosphine (PH3) in the atmosphere of Venus using the James Clerk Maxwell Telescope...
In a new study published in the journal Geoscience Frontiers, a team of U.S. researchers analyzed the ages of 89 well-dated geological events of the last...
Jupiter’s moon Europa harbors underneath a tectonically modified ice shell a salty ocean in direct contact with its rocky interior. Such an oceanic environment...
Volcanic activity on Mars peaked during the Noachian and Hesperian periods, between 3 and 4 billion years ago, with smaller eruptions in isolated locations...
Using data from the Atacama Large Millimeter/Submillimeter Array (ALMA), astronomers from India have detected acetone, disulfur monoxide, and carbon monoxide...
LHS 3844b’s hemispheric tectonics is the direct consequence of a significant temperature contrast between its day- and nightside and is absent in the...
Non-marine animals (amphibians, reptiles, birds and mammals) have apparently experienced at least 10 distinct episodes of intensified extinctions over...
The Islands of Four Mountains, a small group of volcanic islands in the central Aleutians, could actually be part of a single, undiscovered giant volcano...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have spotted airborne plumes of sulfur dioxide (SO2), sulfur monoxide (SO), and...
The end-Permian mass extinction, also known as the Permian-Triassic extinction event and the Great Dying, is the largest mass extinction event in Earth’s...
The Carnian Pluvial Episode, a major climate change event that occurred around 234 to 232 million years ago (Late Triassic epoch), was a time of global...
A team of researchers from the University of Maryland and the Institute of Geophysics at ETH Zurich has identified 37 active circular volcano-tectonic...
The end-Cretaceous mass extinction 66 million years ago eradicated roughly 75% of the animal and plant species on Earth, including whole groups like non-avian...
A team of U.S. astronomers has calculated internal heating rates for 53 terrestrial exoplanets and found that all of them are likely to have volcanic activity...
Mud flows exposed to the low atmospheric pressures found on Mars will behave similar to lava flows in Hawaii or Iceland, also known as pahoehoe flows,...
The 2018 eruption of Kīlauea volcano in Hawaii was likely initiated by prolonged, and at times extreme, rainfall in the months leading up to the event,...
