ESA Science & Technology - Hitomi satellite

Artist's impression of Hitomi (known as ASTRO-H prior to launch), a high-energy astrophysics space observatory, developed by the Japan Aerospace Exploration Agency (JAXA) in collaboration with institutions in Japan, the US, Canada, and Europe.

Covering the energy range between 0.3 and 600 keV, Hitomi will study the dynamics of hot gas in galaxy clusters, the accretion of matter onto supermassive black holes at the cores of distant galaxies, and the acceleration of cosmic-ray particles up to very high energies.
