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

The group, through studying a solar flare from 2017, discovered a spot in the Sun's upper atmosphere filled with trillions of ...

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 ...

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 ...

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 ...

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 ...

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 ...

NASA's Hubble Space Telescope captures the magnificent starry population of the Coma Cluster of galaxies, one of the densest known galaxy collections in the universe — and where the effect of dark ...

According to the laws of physics, the speed of light is a fundamental barrier that cannot be broken - nothing is supposed to be able to travel faster than it. So astronomers were left baffled when ...

The sun radiates far more high-frequency light than expected, raising questions about unknown features of the sun’s magnetic field and the possibility of even more exotic physics. A decade’s worth of ...
