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' of the European Space Agency. The theme poses two key astrophysical questions:
How does ordinary matter assemble into the large-scale structures we see today? and
How do black holes grow and shape the Universe?
