On a rare foggy night, mysterious laser beams seem to play across the MAGIC telescope at Roque de los Muchachos on the Canary Island of La Palma.
The lasers are actually part of a system designed to automatically adjust the focusing of the innovative, seventeen meter wide, multi-mirrored instrument.
The MAGIC (Major Atmospheric Gamma Imaging Cherenkov) telescope itself is intended to detect gamma rays - photons with over 100 billion times the energy of visible light.
As the gamma rays impact the upper atmosphere they produce air showers of high-energy particles.
