Using various telescopes, an international team of astronomers has performed multi-wavelength observations of a recently ...
A dead star accelerates protons to extreme speeds, shedding light on the origin of the most energetic cosmic rays.
A decades-old cosmic mystery has finally been cracked: the strange X-rays coming from the bright star gamma-Cas are caused by ...
The LHAASO observatory has detected gamma rays above 100 TeV from a gamma-ray binary for the first time, challenging current ...
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 ...
LHAASO has uncovered that micro-quasars, black holes feeding on companion stars, are powerful PeV particle accelerators. Their jets produce ultra-high-energy gamma rays and protons that exceed ...
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 ...
For years, scientists have searched for the sources of the most energetic particles in ...
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 ...
