New research reveals more information about the first and oldest of the ‘big five’ extinctions. Around 85% of marine species, most of which lived in shallow oceans near continents, disappeared during that time.

A team has updated its asteroid bombardment model of the Earth with the latest geologic evidence of ancient, large collisions. These models have been used to understand how impacts may have affected oxygen levels in the Earth’s atmosphere in the Archean eon, 2.5 to 4 billion years ago.

It has long been theorized that hydrogen, helium, and lithium were the only chemical elements in existence during the Big Bang, and that supernova explosions are responsible for transmuting these elements into heavier ones. Researchers are now challenging this and propose an alternative model for the formation of nitrogen, oxygen, and water based on the … Challenging the Big Bang puzzle of heavy elements

The more water is dissolved in the magma, the greater the risk that a volcano will explode. A new study now shows that this simple rule is only partially true. Paradoxically, high water content significantly reduces the risk of explosion.

A multidisciplinary team of materials physicists and geophysicists combine theoretical predictions, simulations, and seismic tomography to find spin transition in the Earth’s mantle. Their findings will improve understanding of the Earth’s interior, and help elucidate the impact of this phenomenon on tectonic events including volcanic eruptions and earthquakes.

Ice melange, a slushy mixture of snow and ice chunks, can heal large rifts in Antarctica’s ice shelves. Researchers found that a thinning of ice melange may have enabled a Delaware-sized iceberg to break off from the Larsen C ice shelf in 2017. A new article has the scientists’ analysis of the dynamics behind large … Additional threat to Antarctica’s floating ice shelves

The rise of dinosaurs coincided with environmental changes driven by major volcanic eruptions over 230 million years ago, a new study reveals.

Researchers used decades of measurements of earthshine — the light reflected from Earth that illuminates the surface of the Moon to find that there has been a significant drop in Earth’s reflectance over the past two decades. The Earth is now reflecting about half a watt less light per square meter than it was 20 … Earth is dimming due to climate change
