The image shows a fuzzy glowing ring of red, yellow, and white surrounding a darker center. The team's research was published online today (April 26) in the journal Nature. "The coming years will be exciting, as we will be able to learn more about what happens near one of the most mysterious regions in the universe." “We plan to observe the region around the black hole at the center of M87 at different radio wavelengths to further study the emission of the jet," said Eduardo Ros, also of the Max Planck Institute for Radio Astronomy. Simultaneous observations should allow the team behind this image to disentangle the complicated processes that happen near the supermassive black hole. Using this network of telescopes, astronomers will now work toward better understanding how feeding supermassive black holes launch powerful jets of matter. Milky Way vs M87: Event Horizon Telescope photos show 2 very different monster black holesĪdditionally, the sensitivity of ALMA, which is comprised of 66 antennas in the Atacama desert of northern Chile, GLT, and GMVA, which consists of 14 radio telescopes in Europe and North America, allowed astronomers to use a process called interferometry to synchronize signals from the individual telescopes and properly reveal the black hole shadow and see deeper into the emission of the jet at the same time. Sagittarius A* in pictures: The 1st photo of the Milky Way's monster black hole explained in images What happens at the center of a black hole? This difference revealed that M87's supermassive black hole is gobbling up matter more rapidly than previously believed, scientists said. The size of the ring of the black hole in this new image is also 50% larger than in the EHT image. "At this wavelength, we can see how the jet emerges from the ring of emission around the central supermassive black hole," team member Thomas Krichbaum, of the Max Planck Institute for Radio Astronomy, said in the same statement. The new image of the M87 supermassive black hole also differs from the EHT telescope image as it shows the region in longer wavelengths of light, which affects what astronomers can see in this region. At the center of this glowing golden ring is total darkness, which is the shadow of the black hole. This creates the bright golden ring seen in the EHT's images of the M87 balck hole and the supermassive black hole at the heart of the Milky Way, Sagittarius A* (Sgr A*).

In addition to showing the jet as it emerges from this supermassive black hole, the new image also shows what scientists call the shadow of the black hole. "To study this directly, we need to observe the origin of the jet as close as possible to the black hole." "We know that jets are ejected from the region surrounding black holes, but we still do not fully understand how this actually happens," study team member Ru-Sen Lu, of the Shanghai Astronomical Observatory, said in the same statement. Quite how these supermassive black holes do this isn't fully understood, however.
And some of these behemoths, such as the one at the center of M87, are consuming large amounts of matter in the form of gas and dust - and even unfortunate stars that get too close.Īs a result, these feeding monsters are blasting out powerful jets of matter that move at near-light speed and can extend for many thousands of light-years - sometimes, well beyond the boundaries of the galaxies that house them.
Most or all large galaxies are believed to have supermassive black holes at their hearts. This new image of M87 and the outflow erupting from it was created using 2018 data from radio telescopes with the Global Millimetre VLBI Array (GMVA), the Greenland Telescope and the Atacama Large Millimeter/submillimeter Array (ALMA), which worked together to form a virtual instrument about the size of Earth itself (much as the EHT network does). The historic first image of the M87 central supermassive black hole, which has a mass 6.5 billion times that of the sun and is located 55 million light years from Earth, was taken by the Event Horizon Telescope (EHT) collaboration in 2017 and unveiled two years later.
