ESOcast 25: Chasing Gamma Ray Bursts at Top Speed: The VLT’s Rapid Response Mode

This video podcast explains the ESO Very Large Telescope’s Rapid Response Mode, which makes it possible to observe gamma-ray bursts only a few minutes after they are first spotted. As the optical afterglow of a gamma-ray burst fades extremely rapidly, observations must start as quickly as possible. And the Very Large Telescope has the capability to master this time critical issue better than any other telescope.
