Astronomers have uncovered an unprecedented cosmic phenomenon after identifying an event in which two completely different types of gamma-ray bursts occurred just four minutes apart, all from the same direction. The discovery, reported in the journal Nature Astronomy, could shake up current theories about the universe's most energetic explosions, as experts have yet to find a satisfactory explanation, ScienceAlert reported.
ASTRONOMERS recorded a unique event: a short and a long burst of gamma-rays from the same source 4 minutes apart. The discovery defies all known models and poses a challenge to theorists.
Two Different Kinds of Gamma-Ray Bursts Erupted 4 Minutes Apart. Astronomers Have Never Seen This Before.
Gamma-ray bursts (GRBs) are among the most energetic cosmic events since the Big Bang, releasing the most energetic type of radiation, gamma rays – the stuff that turned unassuming Bruce Banner into the rampaging Hulk, but on an astronomical, potentially planet-sterilizing level. GRBs are classed by transience, including short-duration ones that last less than two seconds and long-duration ones that last over two seconds (possibly much longer).
In about 51 seconds, an explosion in the distant universe unleashed, in an account that ignores that this energy comes out in concentrated beams, more energy than the
