Scientists describe the minute-long blast as 'remarkable'.
A "remarkable" astronomical explosion is thought to have been triggered by the collision of stars with a black hole, scientists have said.A team of scientists including University of Leicester physicists described the minute-long blast as a rare cosmic event.Gamma ray bursts are the most powerful explosions known in the Universe.Scientists said the blast, named GRB 211211A, was relatively lengthy with more infrared light than they would normally expect to see.
Their research suggests the light came from a kilonova, an astral event, thought to be generated as neutron stars and a black hole collide.It included experts from the universities of Birmingham and Leicester as well as Radboud University in The Netherlands.Dr Matt Nicholl, an associate professor at the University of Birmingham, said the research supported the idea that such kilonovae "are the main factories of gold in the Universe".
Dr Gavin Lamb, a post-doctoral researcher at the University of Leicester, said the burst had seen an excess of infrared light from about a day after the burst. Dr Benjamin Gompertz, an assistant professor at the University of Birmingham, added the research had exciting implications for future research."We don't expect mergers to last more than about two seconds. Somehow, this one powered a jet for almost a full minute."
