One or more volcanic eruptions preceded the majority (62 of 68) of dynastic collapses in China over the past 2,000 years, according to new research led...
The Carnian stage (lasted from 237 to 227 million years ago) of the Triassic period marks one of the most significant intervals of the past 250 million...
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...
