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...
Regular light-dark cycles greatly affect organisms, and events like eclipses induce distinctive physiological and behavioral shifts. While well documented...
The origin of life on Earth required a supply of phosphorus for the synthesis of universal biomolecules. Closed lakes may have accumulated high concentrations...
Astronomers from SETI Institute, NASA’s Ames Research Center and Curtin University have traced the impact orbit of 75 observed meteorite falls to several...
According to new research from Keele University and the Universidad de Alicante, near-Earth explosions of giant O- and B-type stars occur at a rate of...
How lightning is started in thunderstorms is poorly known. With a newly-developed 3D mapping and polarization system, physicists at Los Alamos National...
A team of geologists from Curtin University has discovered unequivocal evidence for a hypervelocity meteorite impact 3.47 billion years ago (Archean Eon)...
Heat from our Sun drives atmospheric temperature changes on Earth, which in turn can affect things like rock properties and underground water movement,...
A near-Earth asteroid called 2024 YR4 has been closely monitored in the past couple of months as its odds of impacting Earth in 2032 rose to around 3%....
By chemically analyzing crystals in ancient rocks, scientists from Curtin University, the University of Portsmouth and St. Francis Xavier University discovered...
As our Solar System orbits the Milky Way, it encounters various environments, including dense regions of the interstellar medium. These encounters can...
This supernova event likely occurred in the Upper Centaurus Lupus association, a group of massive stars approximately 457 light-years away from Earth.
