Since its launch in 1999, Chandra has given astronomers a new view of the Universe, revealing previously unseen material around exotic objects by observing their energetic X-ray emissions. In particular, Chandra has been instrumental in our understanding of black holes. For example, Chandra made the first observation of X-ray emissions from the supermassive black hole at the centre of the Milky Way and discovered a new type of black hole in Messier 82.
