Athena

ESA's next great X-ray observatory — designed to study the hot, energetic universe, from the gas that binds galaxy clusters to the black holes that shaped galaxies, at far higher sensitivity than today's X-ray telescopes.

Highlights

  • Europe's next flagship X-ray observatory

Mission goals

  • Study the hot and energetic universe in X-rays
  • Map the hot gas of galaxy clusters and the growth of black holes

Technology

A large X-ray telescope with a high-resolution imaging spectrometer.

Status & uncertainties

Reformulated ('NewAthena') to fit a reduced cost envelope; adoption and launch date are not yet fixed.
