Astronomers think that GRB 221009A is the birth of a newly formed black hole in the heart of a collapsing star. In this figure the black hole creates strong jets of particles that move at a speed close to the speed of light. The jets penetrate through the star, emitting X-rays and gamma rays as they flow into space. Credit: NASA/Swift/Cruz deWilde

Artist's rendering of a gamma-ray burst caused by a powerful collision between two massive neutrino stars after their spiral dance of death. In addition to high-energy radiation and material emitted in a narrow jet, the event is thought to be the main factory in the universe of heavy elements, including gold and platinum. Credit: A.

The radiation originates in binary stars that have merged after being ejected from their galaxy. Usually bursts that do not occur within a galaxy last a few seconds. In such eruptions, heavy elements including gold and platinum are formed

Star-forming galaxies are responsible for generating gamma rays that have not yet been attributed to a known source. The discovery may lead astrophysicists to decipher dark matter

In this image, of the gamma-ray burst called GRB 130925A, a sheath of hot X-ray-emitting gas (in red) surrounds a jet of particles (in white) erupting from the star's surface at near the speed of light. This source may be a metal-poor blue giant, a good approximation of the first stars formed in the universe. Image: NASA/Swift/A. Simonnet, Sonoma State Univ.

This artist illustration, prepared for the Harvard Smithsonian Center depicting two neutron stars at the moment of collision New findings confirm that neutron star collisions cause short bursts of gamma rays in which the rare metals including gold are produced. All the gold on Earth is believed to have come from such neutron star collisions. Image Credit: Dana Berry, SkyWorks Digital, Inc.
