ESA Science & Technology - Athena
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.
31 October 2017Athena, the Advanced Telescope for High-ENergy Astrophysics, is the second Large mission in ESA's Cosmic Vision plan, building upon a remarkable heritage of space observatories devoted to the exploration of the most exotic objects in the Universe.

Traditionally, space has been thought of as a place of serene majesty but X-ray astronomy has shown us the truth: it’s a hot and energetic Universe out there. Even the stars look cool in comparison.
