The LHAASO observatory has detected gamma rays above 100 TeV from a gamma-ray binary for the first time, challenging current ...
A mysterious glow of gamma rays at the center of the Milky Way has long hinted at dark matter, but the lack of similar signals in smaller dwarf galaxies has cast doubt on that idea. Now, researchers ...
For decades, scientists have been trying to solve a mystery: Where do high-energy cosmic rays come from? These charged particles travel from outer space to Earth, but their origins remain unknown. Now ...
GRB 250702B is 'the longest gamma-ray burst that astronomers have ever observed,' according to NOIRLab. See imagery of the ...
A dead star accelerates protons to extreme speeds, shedding light on the origin of the most energetic cosmic rays.
An X8.2 class solar flare flashes in the edge of the Sun on Sept. 10, 2017. This image was captured by NASA's Solar Dynamics Observatory and shows a blend of light from the 171 and 304 angstrom ...
The Large High Altitude Air Shower Observatory (LHAASO) has detected ultra-high-energy gamma rays—exceeding 100 TeV—from the binary system LS I +61° 303, reaching up to 200 TeV. This marks the first ...
A decades-old cosmic mystery has finally been cracked: the strange X-rays coming from the bright star gamma-Cas are caused by a hidden stellar companion feeding off it. Using cutting-edge observations ...
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 ...
