LISA

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.

Highlights

  • A gravitational-wave detector millions of km across

Mission goals

  • Detect low-frequency gravitational waves from space
  • Observe merging massive black holes across the universe

Technology

Three spacecraft in a triangle millions of kilometres apart, linked by laser interferometry.

Status & uncertainties

Adopted by ESA; the precision-formation-flying technology is being matured.
