Death from space. Gamma-Ray Bursts (GRBs), extremely energetic explosions that have been observed in distant galaxies, explained…
There are cosmic snipers firing at random into the universe. What are they and what happens if they hit us?
Gamma-ray bursts (GRBs) are the brightest electromagnetic events known to occur in the universe. Bursts can last from ten milliseconds to several hours.
The intense radiation of most observed GRBs is believed to be released during a supernova or hypernova as a rapidly rotating, high-mass star collapses to form a neutron star, quark star, or black hole.
