Most Distant Object Ever Visible to the Naked Eye

This is technically old news, but the Astronomy Picture of the Day today featured the gamma ray burst from a few weeks ago - they have a nice, concise description. Essentially it was an explosion that occurred half-way across the universe, but was actually visible to the naked eye! The picture might not be the prettiest you can find in astronomy, but the idea of just how bright this thing was, how much energy it had in order for its light to be visible 7.5 billion light-years away - it's mind-numbing! If this doesn't sound amazing to you, you must be missing something.
