What was discovered

A worldwide network of synchronised radio telescopes formed an Earth-sized telescope and obtained the shadow of M87's black hole, of 6.5 billion solar masses; in 2022 it did the same with Sagittarius A*.

Data from ALMA, SMA, IRAM, LMT, SPT, JCMT, SMT and APEX; processed at Haystack (MIT) and Bonn (MPIfR).

What it led to

  • Visual proof of event horizons
  • Tests of general relativity in the strong-field regime
  • Next-generation EHT
