Gamma Ray Bursts - they're neat

How far can the naked eye see? About 7.5 billion light-years. On March 19th, a Gamma Ray Burst was noticed by NASA's Swift satellite and given the name GRB 080319B. It left an optical afterglow estimated at +5 apparent magnitude for 30 seconds, about that of an average star. (Sadly, no one was looking at the area with an optical telescope at that exact time.) Read the original Burst Alert, including the email address of the Burst Advocate, here. Gamma ray bursts and other galaxy-sized energy events previously on MetaFilter.

There can be no escape. . .

NASA's Chandra X-Ray Observatory recently detected [reg required] the largest explosion ever detected in the universe: an eruption releasing the energy of hundreds of millions of gamma ray bursts. Just to put it in perspective, a single GRB releases enough radiation to wipe out just about everything human beings would require for survival in a 1000 light year radius. (The Milky Way spans ~100,000 light years, while the United Federation of Planets spans about 8,000). Arthur C. Clarke has gone so far as suggesting that GRBs might be one of the reasons for Extra-Terrestrial silence: Gamma Ray Bursts are so large and inescapable, a single one would wipe out even an enormous galactic empire. Makes killer asteroids seem downright quaint.

Massive explosion rocks NASA

Massive explosion rocks NASA And Pasadena, and a few other places, too. It's not every day you get to watch a black hole form. Includes cool animation (.mov file). Seems the gamma ray burst detector picks up two or three significant events every month or so.
