The two MAGIC telescopes on the Canary Island of La Palma have been in existence for 20 years. With a mirror diameter of 17 meters and special cameras, they measure what cannot actually be measured on Earth: Gamma rays that reach us from extremely energetic objects in the universe.

Dr. Axel Arbet-Engels of the Max Planck Institute for Physics explains how MAGIC makes such observations possible - and what they tell us, for example, about gigantic black holes at the center of distant galaxies.
