![]() Inside the photon ring is the black hole’s shadow, an area roughly twice the size of the event horizon - its point of no return. The effort was made possible through the ingenuity of more than 300 researchers from 80 institutes around the world that together make up the EHT Collaboration. ![]() That object was more than a thousand times bigger. The image of the Sgr A black hole is an average of the different images the team extracted, finally revealing the giant lurking at the center of our galaxy for the first time. Bright knots constantly form and dissipate in the disk as magnetic. Its their second such image after releasing in 2019 a picture of the giant black hole at the heart of another galaxy called Messier 87, or M87. The black hole’s extreme gravity skews light emitted by different regions of the disk, producing the misshapen appearance. The Event Horizon Telescope (EHT) project took the famous pic. The visualization simulates the appearance of a black hole where infalling matter has collected into a thin, hot structure called an accretion disk. Because the black hole modeled in this visualization is spherical, the photon ring looks nearly circular and identical from any viewing angle. The image of a black hole in the 2014 movie Interstellar looks remarkably different than the one we saw in 2019 when scientists published the first-ever real black hole photo. This so-called “photon ring” is composed of multiple rings, which grow progressively fainter and thinner, from light that has circled the black hole two, three, or even more times before escaping to reach our eyes. The flares have complicated the Event Horizon Telescope (EHT) collaboration’s quest to capture an image of the area immediately surrounding the black hole, and Webb’s infrared data is expected to help greatly in producing a clean image. That object was more than a thousand times bigger. This asymmetry disappears when we see the disk exactly face on because, from that perspective, none of the material is moving along our line of sight.Ĭlosest to the black hole, the gravitational light-bending becomes so excessive that we can see the underside of the disk as a bright ring of light seemingly outlining the black hole. It's their second such image after releasing in 2019 a picture of the giant black hole at the heart of another galaxy called Messier 87, or M87. Glowing gas on the left side of the disk moves toward us so fast that the effects of Einstein’s relativity give it a boost in brightness the opposite happens on the right side, where gas moving away us becomes slightly dimmer. ![]() Viewed from the side, the disk looks brighter on the left than it does on the right. It measures 40 billion km across - three million times the size of the Earth - and has been.
