A Ground-Based View of a GRB

Last week, I posted a view of a recently observed Gamma Ray Burst as seen by the X-ray Telescope abort the Swift satellite. This is what it looked like as seen by the Very Large Telescope at the European Souther Observatory in Chile. The GRB is the red spot near the middle of the image.

After the initial bright flash of a GRB has faded, the afterglow shines at longer wavelengths of visible and infrared light. The team at ESO was able to gather data to show  burst originated from an extremely distant galaxy when the universe was only 6% of its current age. This was one of the oldest GRB yet detected.
