For decades, scientists have been baffled by two enormous structures buried deep inside Earth. These anomalies may retain geochemical signatures distinct...
The Moon formed from a giant impact of the proto-Earth with the ancient protoplanet Theia. In a new study, a team of scientists from the United States,...
Teasing out biochemical information from ancient organic-rich sediments, notably the timing of the emergence of photosynthesis relative to the inferred...
Researchers have discovered an impact crater formed on a granite mountain capped by a thick weathering crust in southern China. Located in Zhaoqing in...
On April 8, 2024, a total solar eclipse disrupted light-dark cycles for North American birds during the lead-up to spring reproduction. Compiling more...
This happens due to plate tectonics and movements in the bedrock, caused by the large ice sheets on top melting and reducing pressure on the subsurface,...
Roughly 4.3 billion years ago, when our Solar System was still in its infancy, a giant asteroid slammed into the far side of the Moon, blasting an enormous...
The leading hypotheses for the origin of the Moon call for a giant impact event between proto-Earth and a separate impactor called Theia. The efficiency...
Tektites are nearly pure glasses (practically no crystalline inclusions) created when a space rock slams into Earth, melting surface material and hurling...
The ozone layer is healing and the Antarctic ozone hole in 2024 was smaller than in previous years, according to a new report from the World Meteorological...
New research suggests dinosaurs were ecosystem engineers that promoted habitat openness in the Late Cretaceous epoch, and their extinction around 66 million...
The atmosphere of Earth during the Mesozoic era, between 252 and 66 million years ago, contained far more carbon dioxide than it does today and total photosynthesis...
While banning ozone-destroying gases such as CFCs has helped the ozone layer to recover, when combined with increased air pollution the impact of ozone...
On July 20 and July 23, 2025, NASA’s Psyche spacecraft looked back toward home and captured images of Earth and our Moon from about 290 million km (180...
In a new paper, Penn State Professor Victor Pasko and his colleagues described how they determined strong electric fields in thunderclouds accelerate electrons...
Submarine canyons are deep, large-scale incisions found on most of the world’s continental margins. In Antarctica, they are widespread features driving...
During periods known as Snowball Earth, between 720 and 635 million years ago, early eukaryotes — complex cellular lifeforms that eventually evolved...
The unusual radio pulses were detected by the Antarctic Impulsive Transient Antenna (ANITA) experiment, a range of instruments flown on NASA balloons high...
The Sun rarely produced extreme solar particle events, orders of magnitude stronger than everything directly observed. Their enormous power can greatly...
