Earlier on this class , an inordinately longGamma Ray Burstsparked a snow flurry of inflammation in the scientific community , move several group toattempttoexplainthe unusual result . Now , an international team of astronomers , including scientists fromPenn Stateand the University of Leicester , has number up with a new , elegantly simple explanation for these enigmatic events . The work is due to be presented next week in St. Petersburg , Russia .
As the name suggests , Gamma - Ray Bursts(GRBs ) are fleeting , vivid clap of da Gamma - ray lightness , which isthe most energetic form of brightness level . These salient explosion are some of themost powerful eventsin the population , shining around amillion trilliontimes brighter than the Sun . On intermediate , these violent event occur aroundonce a 24-hour interval , usually lasting from a few millisecond toseveral mo . It was therefore especially unusual for scientist to observe the energy from one flooding toward Earth for more than five hour .
This rare upshot , which was namedGRB 130925A , is a phallus of a newly recognized course of GRBs address ultra - prospicient bursts . The plosion was observed using the Swift planet ’s X - ray Telescope and the US / Russian satellite Konus - Wind .
The find of these strange events prompted scientist to wonder whether current theories could adequately excuse them , but nonetheless several composition were let go on GRB 130925A. Now , according to a young study , the most likely explanation is much wide-eyed than first look to .
After examining the observation from Swift and Konus - Wind , the researchers find that these ultra - tenacious gamma - ray bursts are actually received explosions , but what sets them aside are the conditions in which they arise . According toPenn Stateprofessor of astronomy David Burrows , all that is necessitate is for the event to occur within a down - density region locate behind a detritus swarm when view from Earth .
“ One cause that these resultant role are satisfying is that scientists generally prefer to find the simplest account for mysterious phenomena,”said Burrows .
