Three telescopes were added to the EHT network before the most recent observing campaign in March 2022, which means future pictures should be sharper and should illuminate subtle details in the areas around black holes. It isn’t clear why there is this mismatch in the spin axes of the black hole and the Milky Way, but it could be related to ancient events in which Sgr A* may have devoured black holes at the centres of smaller galaxies.Īs researchers continue to analyse the black hole data and figure out how the two black holes compare to one another, they also have a new set of observations to examine. The black hole the first, and only, black hole. ![]() Instead of viewing the black hole and its disc from the side, we appear to be viewing it face-on. The black hole lies at the center of an elliptical galaxy called Messier 87 (M87), which is located roughly 55 million light-years from Earth. In this image of M87 taken on 11 April 2017 (a representative example of the images collected in a global 2017 EHT campaign), the shadow of a black hole is. The only thing that doesn’t line up with what was expected is that the accretion disc around Sgr A* appears to be tilted out of alignment with the disc of the galaxy. “Einstein’s doing well, again, and for people who have all their other theories of what gravity could be it might be a little disappointing.” “One of the things which surprises me personally was just how similar these images are to what theory predicts,” says Younsi. When the researchers compared the image of Sgr A* to a library of hundreds of thousands of simulated black holes modelled in scenarios that do not follow general relativity, they found that Sgr A* appears to hew closely to relativistic models. The gravitational pull of Sgr A* is so strong that it bends the light, making the plasma circling towards us appear brighter than that spinning away towards the black hole’s backside. The Event Horizon Telescope project, which produced the world's first image of a black hole in 2019 in the M87 galaxy, unveiled a new view of its magnetic fields as captured by polarized light. The most visible prediction of general relativity is that the ring of light around the black hole ought to be a little lopsided. The historic first image of the M87 central supermassive black hole, which has a mass 6. ![]() This makes them impossible to see directly, and so astronomers have had to use a variety of clever techniques to confirm that they actually exist. Black holes are objects with an intense gravitational pull so strong that not even beams of light, the fastest things in the universe, can escape. ![]()
