The collision of a pair of ultra-dense stars produced the explosion GRB 230307A, which lasted unusually long. In its glow, for a split second, a rhythmic signal at 909 Hz emerged—like the beam of a celestial lighthouse. This pointed not to a black hole but to the birth of a rapidly spinning neutron

Astronomers have directly proven for the first time that a short gamma-ray burst is followed by a prolonged phase of soft X-ray emission. 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
