Researchers from Skoltech, MEPhI, and the Dukhov All-Russian Research Institute of Automation have proposed a new method to ...

Solar physicists say they have found a key source of intense gamma rays unleashed when Earth's nearest star produces its most ...

By tracing solar flare gamma rays, scientists gain new insight into particle behavior that shapes space weather forecasts.

The Sun’s most violent flares are turning out to be even more extreme than I, or many solar physicists, had imagined. By ...

The MAGIC (Major Atmospheric Gamma-ray Imaging Cherenkov) telescope is located in the Canary Islands. Delayed gamma rays from deep space may provide the first evidence for physics beyond current ...

A new way of creating femtosecond, quasi-monoenergetic gamma-ray pulses has been proposed by Serge Kalmykov at the University of Nebraska-Lincoln and colleagues. Their scheme involves using a stack of ...

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still ...

Gamma-ray bursts (GRBs) are among the most explosive and energetic celestial events that have been observed by astronomers. Since its first detection back in the 1960s, scientists have been observing ...

When the core of a massive star collapses, it can eject a jet of gas into space at nearly the speed of light. Collisions between the fast-moving gas and its surroundings, as well as within the jet ...

Teppei Katori and Pierre Lasorak at Queen Mary University of London have studied data from the the T2K neutrino experiment in Japan to search for signs of single gamma-ray emission from neutrino ...

Researchers at the University of North Carolina at Chapel Hill have contributed to new insights into the most long-lived cosmic explosion ever recorded. The event was a gamma-ray burst that remained ...
