(PhysOrg.com) -- The H.E.S.S. telescope system in Namibia discovered a new source of very-high-energy gamma-rays from the direction of the globular cluster Terzan 5. Being very likely located in the outer parts of Terzan 5 this source is the first example for of gamma-ray emission from a globular cluster. The off-centre position of the source and the specific origin of the gamma-rays pose a puzzle for scientists.
