By analyzing the data from various space observatories and ground-based telescopes, European astronomers have performed a ...
A single particle cut through the Mediterranean in February 2023 carrying an almost absurd amount of energy. Detected deep ...
Billions of light years away in a remote part of the universe, two neutron stars – the ultradense remnants of dead stars – collided. The catastropic cosmic event sent light and particles, including a ...
Forces have mediator particles. Electromagnetism is mediated by the photons, for example. So most of the decay of this excited dark matter particle would be this unknown mediator. The excited state ...

Add Yahoo as a preferred source to see more of our stories on Google. The orange dot at the center of this image represents a powerful explosion that repeated several times over one day. - A. Levan, A ...
Astronomers have detected a gamma-ray burst (GRB) like none other. GRB 250702B was longer than any ever observed and repeated ...
Spanish astronomers have conducted a near-infrared study of an ultra-high energy gamma-ray source designated LHAASO J2108+5157. The new study, published February 11 on the arXiv preprint server, tries ...
Gamma-ray binaries represent one of the most dynamic and intriguing classes of high-energy astrophysical systems. These binaries typically consist of a massive star and a compact object – often a ...
