An international team of astronomers has detected a teraelectronvolt (TeV) emission from a gamma-ray burst designated GRB 190114C. The discovery could improve the understanding of very high energy (VHE) sources in the universe. ...
Neutron stars are the end products of massive stars and gather together a large part of the original stellar mass in a super-dense star with a diameter of only around ten kilometers. On 17 August 2017, researchers observed ...
