The discovery by the Einstein Probe telescope links gamma-ray bursts with gravitational waves and will allow more precise localization of neutron star and black h

Invisible Black Hole Shreds Star in a Galactic Suburb

Normally, black holes rip stars apart in the centers of galaxies. A new discovery shows that some black holes lurk in the outskirts. Astronomers spotted a flare tens of thousands of light-years from the center of a large galaxy. A computer algorithm trained on similar events helped identify it. Soon
