Brightest Explosion Ever Seen in the Universe | VIDEO
A mysterious blast of light spotted earlier this year near the constellation Leo was actually the brightest gamma-ray burst ever recorded, and was triggered by an extremely powerful stellar explosion, new research reports.
On April 27, several satellites — including NASA's Swift satellite and Fermi Gamma-ray Space Telescope — observed an unusually bright burst of gamma radiation. The explosion unleashed an energetic jet of particles that traveled at nearly the speed of light, researchers said.
"We suddenly saw a gamma-ray burst that was extremely bright — a monster gamma-ray burst," study co-author Daniele Malesani, an astrophysicist at the Niels Bohr Institute at the University of Copenhagen in Denmark, said in a statement. "This [was] one of the most powerful gamma-ray bursts we have ever observed with the Swift satellite." . . .
