A Cosmic Blast Showed How Its Light Is Born

For the first time in a gamma-ray burst GRB 221009A, astronomers noticed how the light fingerprints of elements were born and reddened. It turned out that particles of light emerged when matter met antimatter, and then, colliding with electrons, lost energy — like a billiard ball after a series of h

Invisible Lighthouse: Magnetar Pulse in a Gamma-Ray Burst

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

X-ray Thunder After Gamma-ray Lightning

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
