Astrophysics Observatories

The great observatories of the coming decades — surveying dark energy, imaging habitable worlds, and opening the low-frequency gravitational-wave and X-ray skies.

In brief

The next generation of space observatories.

Missions in this theme

  • AthenaMission concept
    Under study · In reformulation; launch envisaged in the late 2030s

    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.

  • Under study · In early design; launch envisaged in the 2040s

    NASA's next flagship space telescope, recommended by the astronomy decadal survey — designed to directly image potentially habitable planets around other stars and search their atmospheres for signs of life.

  • LISAMission concept
    In development · Launch planned in the mid-2030s

    A space-based gravitational-wave observatory — three spacecraft forming a giant laser interferometer to hear the low-frequency ripples in spacetime that ground detectors cannot, from the mergers of the largest black holes.
