Bennu looked far different up close than scientists expected, and that mismatch led to a deeper investigation into how asteroid surfaces behave. What researchers found in returned samples helped ...

Astronomers have used the James Webb Space Telescope to capture the most detailed look yet at the atmosphere of Kepler-51d, a planet so lightweight it has been compared to cotton candy. The new data ...

In one of the biggest surprises of NASA's OSIRIS-REx mission, its target asteroid, Bennu, turned out to be a jagged, rugged ...

"Hearst Magazines and Yahoo may earn commission or revenue on some items through these links." Theorized by physicist David Pines in 1956, this demon (also known as Pine’s Demon) is a plasmon—a ...

The Sun unleashes a torrent of charged particles. Some of them slam into the Earth’s atmosphere, triggering breathtaking auroras in the night sky. But for equipment that’s orbiting our planet in outer ...

Cosmic rays are extremely fast, charged particles that travel through space at nearly the speed of light. The Amaterasu particle was detected in 2021 by the Telescope Array experiment in the U.S. It ...

Planned to be the largest particle accelerator in the world, China's Circular Electron Positron Collider (CEPC) was meant to be about 100 kilometers or 62 miles long. That's much bigger than CERN's ...

Structural batteries are a "massless" alternative to traditional batteries because they are designed to produce and store energy while also serving as a load-bearing part of a vehicle's structure. A ...

One method for visualizing dynamic biological processes is single particle tracking, a localization microscopy method. For this technique to be successful, several factors need to be considered, ...

Ninety million times a year, when protons crash together at the Large Hadron Collider (LHC), they produce, in their wreckage, a top quark and an anti-top quark, the heaviest known elementary particles ...

Every time two beams of particles collide inside an accelerator, the universe lets us in on a little secret. Sometimes it's a particle no one has ever seen. Other times, it's a fleeting glimpse of ...
