by Astronomers just detected what may be the most powerful flash of light ever seen.
The so-called gamma-ray burst, the most energetic type of electromagnetic explosion known to exist in the universe, was first spotted by telescopes Sunday (Oct. 9).
Gamma-ray bursts, which were discovered accidentally by U.S. military satellites in the 1960s, are likely produced when giant stars explode at the ends of their lives before collapsing into black holes, or when ultradense stellar remnants known as neutron stars collide.
Within seconds, these explosions unleash as much energy as the sun will emit during its entire 10-billion-year lifetime.
