Gamma-ray bursts (GRBs) are flashes of gamma rays from extremely energetic explosions.

The burst was proclaimed to be the most energetic explosion to have ever occurred since the Big Bang, earning it the nickname Big Bang 2.

Before the 1990s, the term "hypernova" was used sporadically to describe the theoretical extremely energetic explosions of extremely massive population III stars.

How are the most energetic explosions in the universe and an ordinary cell phone connected within MSFC's operations center for Fermi, NASA's newest gamma-ray observatory?

This flare is thought to be the most energetic magnetic explosion ever witnessed by man.

This demonstrated that the transient was associated with an energetic explosion of a low-mass 10 M star.

Several telescopes at La Silla played a role in linking gamma-ray bursts, the most energetic explosions in the universe since the Big Bang, with the explosions of massive stars.

"Just how energetic an explosion is a supernova?"

Gamma-ray bursts (GRBs) are flashes of gamma rays associated with extremely energetic explosions that have been observed in distant galaxies.

If the beam happens to be pointed toward Earth, a brilliant flash could result from a less energetic explosion.
