Astronomers Uncover a Remarkable New Method to Annihilate Stars

Astronomers have made a fascinating discovery regarding the destruction of stars. By colliding ancient remnants of stars, a massive explosion and a gamma-ray burst visible throughout the Universe can be produced, instilling fear and awe. The event GRB 191019A, detected in 2019, revealed the collision of stellar remnants near the central supermassive black hole of an old galaxy. This unexpected occurrence sheds light on a new pathway for stellar deaths. In the dense core regions of ancient galaxies, large populations of stars, gas, dust, black holes, and neutron stars coexist. The gravitational influence of the central black hole can bring these objects close together, leading to powerful collisions and the production of long-duration gamma-ray bursts. Such events are often obscured in galaxy cores, but the discovery of GRB 191019A paves the way for further exploration and understanding of these phenomena. The collaboration between different observatories plays a crucial role in studying gamma-ray bursts, allowing for a comprehensive analysis across the electromagnetic spectrum and the potential detection of gravitational waves.
