Johnson said 'only a trickle of material is actually making it all the way to the black hole.' It seems that black holes like doughnuts,' she joked. And yet, when we look at the heart of each black hole, we find a bright ring surrounding the black hole's shadow.

But perhaps more importantly, the one in M-87 launches a powerful jet that extends as far as the edge of that galaxy. 'The one in M-87 is accumulating matter at a significantly faster rate than than Sgr A*. But the two black holes couldn't have been (more) different from each other in practically every other way. This makes the two images appear very similar to us when we gaze at them in the sky. 'But it is also 2,000 times farther away from us.

M-87's black hole 'is 1,500 times more massive, making its horizon 1,500 times larger,' Özel said. The EHT image of Sgr A* is similar in appearance to the historic image of M-87's huge black hole and closely resembles what astronomers expected based on computer simulations running the equations of Einstein's general theory of relativity. Gas, dust, wayward stars and the light they emit, anything crossing that invisible line vanishes from the known universe. The event horizon is the invisible boundary between a black hole and the rest of the universe, a zone where nothing, not even light, can escape the hole's gravitational clutches. That image shows Sgr A*'s dark central core - the shadow of its 'event horizon' - surrounded by a lopsided ring of light emitted by particles racing around the hole at nearly the speed of light. The Event Horizon Telescope captured the first actual image of the massive object. The 2020 Nobel Prize went to three researchers whose pioneering observations and analysis all but confirmed the presence of a supermassive black hole. Analyzing those trajectories, astronomers conclude the unseen black hole has the mass of 4 million suns. An animation shows how the gravity of the Milky Way's central black hole warps the trajectories of nearby stars.

The motions of stars in the dust-shrouded core of the Milky Way near Sgr A* have been closely monitored for the past two decades, allowing astronomers to calculate the mass of the invisible body warping their trajectories. Light that is too close to the black hole, close enough to be swallowed by it, eventually crosses its horizon and leaves behind just the dark void in the center.'īy definition, black holes cannot be directly observed because nothing, not even light, can escape the crushing inward force of their titanic gravity.īut their presence can be indirectly detected by observing the effects of that gravity on the trajectories of nearby stars and by the radiation emitted across the electromagnetic spectrum by material heated to extreme temperatures as it's sucked into a rapidly rotating 'accretion disk' and then into the hole itself. 'Light escaping from the hot gas swirling around the black hole appears to us as the bright ring. Its enormous gravity pulls surrounding material into a disc, accelerating it to nearly the speed of light and heating it to extreme temperatures, resulting in torrents of radiation that can be seen from Earth. The 2019 target was a mind boggling black hole at the core of M-87, a giant elliptical galaxy in the constellation Virgo, a hole with the mass of 6.5 billion suns. 'And it is teeming with activity, always burbling with turbulent energy and occasionally erupting into bright flares of emission.' The black hole at the center of the Milky Way, known as Sagittarius A*, or Sgr A*. 'We are peering into a new environment, the curved spacetime near a supermassive black hole,' said Michael Johnson, a researcher at the Harvard-Smithsonian Center for Astrophysics. Three years after capturing the first image of a supermassive black hole in a galaxy 55 million light years away, astronomers have managed to 'photograph' the gaping maw of the smaller but much closer black hole quietly lurking at the core of the Milky Way, researchers announced Thursday.
