18 Ιαν 2012 · The Event Horizon Telescope (EHT) collaboration has published new results that describe for the first time how light from the edge of the supermassive black hole M87* spirals as it escapes the black hole’s intense gravity, a signature known as circular polarization.

12 Μαΐ 2022 · Scientists are particularly excited to finally have images of two black holes of very different sizes, which offers the opportunity to understand how they compare and contrast. They have also begun to use the new data to test theories and models of how gas behaves around supermassive black holes.
10 Απρ 2019 · The main goal of BlackHoleCam and the Event Horizon Telescope (EHT) is to make the first ever images of the billion solar masses black hole in the nearby galaxy M87 and of its smaller cousin, Sagittarius A*, the supermassive black hole at the centre of our Milky Way.

We used radio astrometry to refine the distance to the black hole x-ray binary Cygnus X-1, which we found to be 2.22 − 0.17 + 0.18 kiloparsecs. When combined with archival optical data, this implies a black hole mass of 21.2 ± 2.2 solar masses, which is higher than previous measurements.
4 Αυγ 2023 · The recent Chandra-JWST discovery of a quasar in the z = 10.1 galaxy UHZ1 reveals that accreting supermassive black holes (SMBHs) were already in place 470 million years after the Big Bang.
