Wildfire smoke is usually discussed as an airborne pollutant and a threat to human health. But when smoke and rain coincide, nutrients released by burned landscapes rain back down. A new study finds that smoke-rain events ...
Dark matter is known to make up roughly 85% of all mass in the universe, as evidenced by the way galaxies spin and how galaxy clusters are held together under gravity. Yet despite decades of searching, physicists have never ...
As wildfire smoke plumes travel thousands of miles, sunlight and atmospheric chemistry bleach their color, strip away their campfire aroma and add them to the mix of urban smog.
Galaxies are like cosmic gems, each with characteristics including size and shape that make them distinct. A new gallery released today from NASA's Chandra X-ray Observatory and other telescopes displays a collection of galactic ...
Every high-energy nuclear collision leaves behind a trail of clues about the structure of atomic nuclei. Deciphering those clues, however, depends on the accuracy of the underlying theory. Physicists at Osaka Metropolitan ...
A team of scientists from Caltech and Yale University has shown for the first time how to accurately quantify an important quantum phenomenon in metals, called the Kondo effect, for specific real materials. Unlike previous ...
The universe is known to be expanding at an accelerating rate. Physicists typically attribute this acceleration to dark energy, a mysterious component of the universe that exerts negative pressure, causing space to expand ...
Pennsylvania ranks second in U.S. natural gas production, accounting for about one-fifth of U.S. output in 2024, and has one of the most extensive histories of energy extraction in the country. A team of researchers from ...
Around 4.6 billion years ago, the solar system was little more than a giant ball of gas and dust. Over the next few million years, this "solar nebula" underwent a huge transformation, flattening into a disk of matter that ...
At the center of our solar system, the sun influences every planet that orbits it. In two recent studies, scientists uncovered how ancient events in the sun's history may have helped create Earth's unique climate and driven ...
