Athena – Advanced Telescope for High-ENergy Astrophysics – will be an X-ray telescope designed to address the Cosmic Vision science theme 'The Hot and Energetic Universe'. By combining a large X-ray telescope with state-of-the-art scientific instruments, Athena will be able to make an important contribution to answering these questions. In 2014, Athena was selected as the second large (L-class) mission in ESA's Cosmic Vision programme.
