first image of a black hole

"The image shows an intensely bright "ring of fire", as Prof Falcke describes it, surrounding a perfectly circular dark hole. Music: Niklas Falcke | As more telescopes are added and the rotation of Earth is factored in, more of the image can be resolved, and we can expect future images to be higher resolution. A team formed to take on the challenge, creating a network of telescopes known as the Event Horizon Telescope, or the EHT. Details have been published today in Astrophysical Journal Letters.It was captured by the Event Horizon Telescope (EHT), a network of eight linked telescopes.Prof Heino Falcke, of Radboud University in the Netherlands, who proposed the experiment, told BBC News that the black hole was found in a galaxy called M87. Image credit: The data also offer some insight into the formation and behavior of black hole structures, such as the accretion disk that feeds matter into the black hole and plasma jets that emanate from its center.

Although the famed physicist was skeptical that black holes even existed, solutions to his equations for the general theory of relativity, which he M87’s image matches that prediction, although the ring of light is a bit uneven, making it look like a bulgy donut. One solar mass is equivalent to the mass of our Sun, approximately 2x10^30 kilograms. “Nature has conspired to let us see something we thought was invisible.”The Event Horizon Telescope initially set out to snag an image of the supermassive black hole at the core of our galaxy, the Seeing into the heart of our galaxy turned out to be a bit more complicated than staring down the barrel of a black hole in the next galaxy cluster over, which is why M87’s portrait is out first.Rather than being a single snapshot, like the many spectacular photos taken by the To resolve these supermassive black holes—which are tiny compared to their surrounding galaxies—the consortium needed to harness the power of radio telescopes all over the planet. Odd though it may sound, that is harder than getting an image from a distant galaxy 55 million light-years away. Credit: C. Fromm and L. Rezzolla (To test VLBI for imaging a black hole and a number of computer algorithms for sorting and synchronizing data, the Event Horizon Telescope team decided on two targets, each offering unique challenges.The closest supermassive black hole to Earth, Sagittarius A*, interested the team because it is in our galactic backyard – at the center of our Milky Way galaxy, 26,000 light-years (156 quadrillion miles) away.

The Event Horizon Telescope—a planet-scale array of ground-based radio telescopes—has obtained the first image of a supermassive black hole and its shadow. There, the pull of M87’s immense gravity would be the same across your body, from your head to your toes. (Powerful radio telescopes around the world can be synchronized to work together, enhancing their resolution beyond what any single telescope could achieve. The image is not a photograph but an image created by the Event Horizon Telescope (EHT) project. Here, space-time never stands still and is perpetually rotating. In addition to its size, M87* interested scientists because, unlike Sagittarius A*, it is an active black hole, with matter falling into it and spewing out in the form of jets of particles that are accelerated to velocities near the speed of light. As each telescope acquired data from the target black hole, the digitized data and time stamp were recorded on computer disk media. The more telescopes in the array that are widely spaced, the better the image resolution.This video shows the global network of radio telescopes in the EHT array that performed observations of the black hole in the galaxy M87.
