"Although they are relatively simple objects, black holes raise some of the most complex questions about the nature of space and time, and ultimately of our existence," he said. The Event Horizon Telescope (EHT), a network of radio antennae around the globe, has captured the first image of a black hole event horizon.

This jet, seen in detail from Chandra in the inset, extends more than 1,000 light years from the center of the galaxy. Messier 87 (M87), also known as Virgo A or the Smoking Gun, is a supergiant elliptical galaxy located in the core of the Virgo Cluster, in the southern constellation Virgo.. ... which is why it can be seen at such distance from Earth. The bright halo is caused by superheated gas falling into the hole. The galaxy has an apparent magnitude of 9.59 and lies at a distance of 53.5 million light years from Earth. This black hole is located in Messier 87, or M87, which is about 60 million light years from Earth. Future questions the Chandra data may help explore include: How do black holes accelerate some particles to the very high energies that scientists have seen?
"The team is also imaging the supermassive black hole at the centre of our own galaxy, the Milky Way. Chandra has studied M87 many times over its 20-year mission and sees a much wider field-of-view than the EHT. The dark centre is not a black hole but indicates that stars are densely packed and fast moving Chandra has a much larger field of view than the EHT, so it can view the full length of the jet of high-energy particles launched by the intense gravitational and magnetic fields around the black hole at M87. Katie Bouman a PhD student at MIT developed an algorithm that pieced together the data from the EHT. No-one really knows how the bright ring around the hole is created. Without her contribution the project would not have been possible. This is because, for some unknown reason, the "ring of fire" around the black hole at the heart of the Milky Way is smaller and dimmer. The first ever picture of a black hole: It's surrounded by a halo of bright gas The black hole at the center of M87, on the other hand, is a whopping 1,000 times bigger than our own, but it also sits roughly 2,000 times farther away.

A BLACK HOLE’S HOME The galaxy M87 sits about 55 million light-years from Earth in the constellation Virgo. "Breakthroughs in technology, connections between the world's best radio observatories, and innovative algorithms all came together to open an entirely new window on black holes. Chandra's studies of this hot gas have given astronomers insight into the behavior and properties of the giant black hole.The Event Horizon Telescope is an international collaboration whose support includes the National Science Foundation.

On behalf of the EHT's Multiwavelength Working Group, Dr. Joey Neilsen of Villanova University and his collaborators put in a request for Director's Discretionary Time to observe M87 simultaneously with the EHT, and received nearly 30,000 seconds of observing time during April 2017.Neilsen, Villanova undergraduate student Jadyn Anczarski, and their collaborators used Chandra and NuSTAR to measure the X-ray brightness of the jet, a data point that EHT scientists used to evaluate their models of the jet. Prof Falcke told me that he felt that "it's mission accomplished".He said: "It has been a long journey, but this is what I wanted to see with my own eyes. How does the black hole produce the spectacular jets that Chandra and Hubble have studied for many years? Using the Event Horizon Telescope, an international team of scientists has for the first time measured the radius of a black hole at the center of M87, a galaxy some 50 million light years from the Milky Way.. And it is one of the heaviest black holes that we think exists. "No single telescope is powerful enough to image the black hole. The second-largest black hole as seen from Earth, the one at the center of the galaxy M87, is around... [+] 1000 times larger than the Milky Way's black hole, but is over 2000 times farther away. ... told BBC News that the black hole was found in a galaxy called M87. These are external links and will open in a new windowAstronomers have taken the first ever image of a black hole, which is located in a distant galaxy.It measures 40 billion km across - three million times the size of the Earth - and has been described by scientists as "a monster".The black hole is 500 million trillion km away and was photographed by a network of eight telescopes across the world. At the time, no-one thought it was possible. So far, it looks like Einstein is correct once again." The Smithsonian Astrophysical Observatory in Cambridge, Massachusetts, controls Chandra's science and flight operations.Credit: X-ray: NASA/CXC/Villanova University/J. I wanted to know is this real? Unlike the Milky Way’s stunning spirals, M87 is a blobby giant elliptical galaxy. He also recalled reading a scientific paper from 1973 that suggested that because of their enormous gravity, black holes appear 2.5 times larger than they actually are.These two factors suddenly made the seemingly impossible, possible. Prof Doeleman described the achievement as "an extraordinary scientific feat".
"It is remarkable that the image we observe is so similar to that which we obtain from our theoretical calculations.

Without her contribution the project would not have been possible. 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.

So, in the biggest experiment of its kind, Prof Sheperd Doeleman of the Harvard-Smithsonian Centre for Astrophysics led a project to set up a network of eight linked telescopes.
