March 21, A powerful gamma ray burst detected March 19th by NASA's Swift satellite has shattered the record for the most distant object that could be seen with the naked eye. Swift's Burst Alert Telescope picked up the burst at a. EDT on March 19, , and pinpointed the coordinates in the constellation Bootes. Telescopes in space and on the ground quickly moved to observe the afterglow. The burst was named GRB B and registered between 5 and 6 on the visual magnitude scale used by astronomers.
'Naked Eye' Gamma Ray Burst Was Aimed Squarely At Earth

September 10, Now a team of astronomers from around the world, including the University of Leicester, the Mullard Space Science Laboratory of University College London and Liverpool John Moores University, have combined their data from satellites and observatories to explain what happened. They show that the jet from a powerful stellar explosion in a galaxy halfway across the Universe was aimed almost directly at Earth. GRBs are the Universe's most luminous explosions. Within minutes many more telescopes were observing, allowing for the most detailed study of a bright GRB ever undertaken using data from gamma-ray to radio wavelengths. A team of astronomers led by Judith Racusin of Penn State University, present their findings in a paper to appear in the September 10 issue of the journal Nature , following work first presented at the May meeting of the Royal Astronomical Society.

Long bursts are shown in gray. In harder bandpasses the extended emission is likely to be much fainter; this point should therefore be treated as an upper limit.
