For more than ten years, astronomers have observed an enigmatic gamma glow coming from the heart of our Milky Way. Known as ...

New research has failed to rule out self-annihilating dark matter as the source of a gamma-ray emission radiating from the ...

The Mysterious Glow at the Center of Our Galaxy For years, scientists have marveled at the enigmatic gamma-ray glow emanating from the center of the Milky Way. This persistent radiance has puzzled ...

A nearby supernova in 2023 offered astrophysicists an excellent opportunity to test ideas about how these types of explosions boost particles, called cosmic rays, to near light-speed. But surprisingly ...

In the 1990s, NASA satellites built to spot high-energy particles coming from supernovae and other celestial-sized objects discovered a surprise—high energy gamma radiation bursts coming from right ...

Solar physicists say they have found a key source of intense gamma rays unleashed when Earth's nearest star produces its most violent eruptions. In findings published in Nature Astronomy, scientists ...

At the center of our galaxy, there’s a mysterious, diffuse glow given off by gamma rays — powerful radiation usually emitted by high-energy objects such as rapidly rotating or exploding stars. NASA’s ...

M87 was the first black hole to be imaged, and now it's revealing details of how some elementary particles are accelerated by the universe's most extreme environments. Reading time 2 minutes A group ...

Everything on the electromagnetic spectrum has some properties of both waves and particles, but it’s difficult to imagine a radio wave, for example, behaving like a particle. The main evidence for a ...

There appear to be too many gamma rays coming from the sun. New higher-energy measurements reveal that this excess continues for a bit, then disappears — a cutoff that could help clarify what’s going ...
