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

Cosmic extremism: The unusual structure of the jet of the brightest gamma-ray burst of all time

The unusual jet structure reveals unique features of the relatively nearby gamma-ray burst that can be studied in better detail than the gamma-wave bursts discovered so far
This image provides three different perspectives on the gamma ray burst GRB150101B, which is similar to the event where gravitational waves were measured and simultaneously also in the electromagnetic spectrum and there is a similarity between the two cases. In the center, an image from the Hubble Space Telescope shows the galaxy where the GRB150101B burst occurred. In the top corner, two X-ray images from NASA's Chandra X-ray Observatory show the event as it appeared on January 9, 2015 (left), and as seen about a month later, on February 10, 2015 (right), as the explosion halo fades, point The bright light is the nucleus of the galaxy.Photo: NASA/CXC

This artist's illustration, prepared for the Harvard Smithsonian Center, depicts two neutron stars at the moment of collision. New findings confirm that collisions of neutron stars 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. illustration

The gold on Earth was created in neutron star collisions
