Abstract : Gamma-ray bursts (GRBs) are bursts of X-rays and gamma-rays for a typical duration of a few to a few tens of seconds, which are known to be the largest explosions in the universe. The long-waited opportunity of probing the most distant (i.e., the earliest) universe by using these mysterious phenomena has finally been realized by the Subaru Telescope. Here we introduce this latest result and the thrilling story of this epoch-making observation, in the heavy competition with the largest telescopes on the globe.. ¼H. 2007 1 ¼.
