![]() There are many remaining questions about black holes that the coordinated NASA observations may help answer. Other insights may come as researchers continue to pore over these data. Scientists used this information to compare their models of the jet and disk around the black hole with the EHT observations. While NASA observations did not directly trace out the historic image, astronomers used data from NASA's Chandra and NuSTAR satellites to measure the X-ray brightness of M87's jet. If EHT observed changes in the structure of the black hole's environment, data from these missions and other telescopes could be used to help figure out what was going on. NASA's Fermi Gamma-ray Space Telescope was also watching for changes in gamma-ray light from M87 during the EHT observations. As part of this effort, NASA's Chandra X-ray Observatory, Nuclear Spectroscopic Telescope Array (NuSTAR) and Neil Gehrels Swift Observatory space telescope missions, all attuned to different varieties of X-ray light, turned their gaze to the M87 black hole around the same time as the EHT in April 2017. To complement the EHT findings, several NASA spacecraft were part of a large effort, coordinated by the EHT's Multiwavelength Working Group, to observe the black hole using different wavelengths of light. By getting radio telescopes around the world to work in concert like one instrument, the EHT team achieved this, decades ahead of time." "Years ago, we thought we would have to build a very large space telescope to image a black hole. "This is an amazing accomplishment by the EHT team," said Paul Hertz, director of the astrophysics division at NASA Headquarters in Washington. Catching its shadow involved eight ground-based radio telescopes around the globe, operating together as if they were one telescope the size of our entire planet. This black hole is 6.5 billion times the mass of the Sun. The stunning new image shows the shadow of the supermassive black hole in the center of Messier 87 (M87), an elliptical galaxy some 55 million light-years from Earth. Against a bright backdrop, such as this disk, a black hole appears to cast a shadow. By its very nature, a black hole cannot be seen, but the hot disk of material that encircles it shines bright. Anything that comes within a black hole's "event horizon," its point of no return, will be consumed, never to re-emerge, because of the black hole's unimaginably strong gravity. includes the National Science Foundation.Ī black hole is an extremely dense object from which no light can escape. EHT is an international collaboration whose support in the U.S. Scientists can then use the research to further our knowledge of how black holes work, and how they continuously feed on the particles around them.A black hole and its shadow have been captured in an image for the first time, a historic feat by an international network of radio telescopes called the Event Horizon Telescope (EHT). ![]() ![]() McKinley also said that because Centaurus A is so close to Earth, there’s a lot we can learn from observing the black hole that sits at the center of that galaxy. Now, though, this new image provides a deeper insight into the details around the eruption.ĭr. That caused the image to become distorted around the ejections. He also said that previously the observations they made couldn’t handle the extreme brightness from the blackhole erupting. “It forms a disc around the blackhole, and as the matter gets ripped apart going close to the black hole, powerful jets form on either side of the disc, ejecting most of the material back out into space, to distances of probably more than a million light years,” he said in the news release. Benjamin McKinley from Curtin University says the radio waves in the image are from all the particles the black hole is feeding on. Digging deeper Image source: Paulista/Adobeĭr. A paper on the discovery was published in the journal Nature Astronomy. ![]() The astronomers also say that the photo is the most comprehensive we’ve captured of a black hole erupting. They captured this particular image using the Murchison Widefield Array (MWA) telescope in Western Australia. When viewed in that way, Astronomers say the eruption spans the same length of 16 full Moons side by side. They captured the photograph of the black hole erupting from Earth. ![]()
