This is the moment that change everything in astronomy and astrophysics. This is the first-ever picture of the event horizon of a black hole. M87's one

It looks like a ring of fire, it has a diameter of billions km. It may look like something disappointing, but it's finally real

Science and turned something which has been a mere mathematical entity for years, into a physical object that can be viewed and measured repeatedly. It took time, but we got it

The physics of the shape of what it may look like a ring of fire, tells us that something is rotating there: it may be either the black hole itself, or the matter orbiting it

That "something rotating" may be the black hole itself, matter, but more importantly light [source of the gif: ]

The first-ever image of a black hole (M87 or Virgo A, left) is here compared with a simulation (middle) and the simulation blurred to the expected resolution of the telescope (right)

M87's supermassive black hole is billions of times the Sun's mass: estimates have ranged from (3.5 ± 0.8) × 10⁹ M☉ to (6.6 ± 0.4) × 10⁹ M☉. The disk rotates at velocities of up to 1,000 km/s & spans a maximum diameter of 0.12 parsecs (0.39 light-years)

This is the scale of M87's black hole, which we saw today in direct observations vs our Solar System vs M60's central black hole [source of the gif: ]

To wrap this thread up, just a note about the emotional balance too: it was a thrilling afternoon and the teams' explanations were amazing, but when Monica Moscibrodzka talked, her voice told about an immense passion, and I could not hold back some tears
