Scientists trace high-energy particles to the sun’s plasma

Scientists may have discovered when and how the high-energy particles that bombard the Earth and other objects emerge from violent environments like sun atmosphere. These high-energy particles pose a threat to sensitive satellite technology And astronauts, and can even affect aircraft flying over the North Pole. Although researchers have been studying these particles for decades, … Read more

NASA prepares to deflect an asteroid, in a major test of planetary defense

A man sits at his work station inside the mission operations center of the Dual Asteroid Redirection Test (DART) spacecraft, which is rapidly approaching its target. I bet dinosaurs wish they’d thought about that. On Monday, NASA will attempt a feat humanity has never accomplished before: deliberately smashing a spacecraft into an asteroid to twist … Read more

The deepest scientific drilling in the ocean sheds light on the upcoming Great Japan Earthquake

Catching neutrinos in the LHC

CERN physicist Jimmy Boyd enters a tunnel near the ATLAS detector, an experiment at the world’s largest particle accelerator. From there, it turns into an underground space called TI12. “This is a very special tunnel,” Boyd says, “because that’s where the old transmission line of the Large Electron-Positron Collider used to be, before the Large … Read more

Researchers identify a new method for measuring the high energy density of plasma and facilitating self-confinement fusion

Experimental setup. Scheme of experimental setup for each shot: (1) selection of a 500 kV energy proton beam from the initial broadband TNSA spectrum generated by the main beam, (2) generation of a WDM sample by the heater beam, (3) downshift measurement of the proton energy spectrum of the selected beam after Passing through the … Read more
