The Gamma-Ray Burst (IMAGE) University of Copenhagen - Niels Bohr Institute Caption The gamma-ray burst is extremely bright and is the most luminous object in the field, as seen in the image from Swift. All the other luminous objects seen in the image are stars from our own galaxy, while the gamma-ray burst is millions of times farther away. This section shows an area of the sky that roughly corresponds to a quarter the size of the full moon.
