Flaming Sky over Paranal
In this ghostly night picture, taken at Paranal Observatory, we can see three out of four VLT Auxiliary Telescopes. Each one of them is a 1.8-metre telescope designed to work along with the other three as a single telescope, thanks to the VLT Interferometer.
In the background, the quiet beauty of the Atacama sky is enhanced by a red aurora-like shimmer, called airglow, which is caused by light-emitting chemical reactions in the atmosphere. Normally, those emissions are not so strong, but the night this image was taken they were unusually bright, producing this unusual picture.
