The M 87 black hole, the first body of its type ever photographed by astronomers at the Earth Horizon Telescope, shows an unusual glitter\u2026<\/em><\/strong><\/p>\n

The diameter of all rings is similar, but the location of the bright side varies. The variation of the thickness of the ring is most likely not real and results from the limited number of participating VLBI stations in earlier experiments. Image credit: \u00a9 : M. Wielgus, D.

T<\/span>he first image of a black hole released in 2019 showed the body at the center of the galaxy M87 to look almost exactly as Albert Einstein predicted a century before.<\/p>\n

A new analysis of data from that study sheds additional light on the lightless object \u2014 The ring is glittering.<\/p>\n

\u201cThe results announced in <\/span>April 2019 show an image of the shadow of a black hole, consisting of a bright ring formed by hot plasma swirling around M 87*, and a dark central part, where we expect the event horizon of the black hole to be,\u201d states Maciek Wielgus, astronomer at Harvard University.<\/p>\n

The Earth Horizon Telescope (EHT), a global network of radio telescopes<\/a>, provides astronomers an instrument capable of recording images with resolutions as detailed as that taken by an instrument as large as Earth. This array first recorded limited data from the M87 black hole<\/a> in 2009, and other images were collected through 2013.<\/p>\n

The 2019 image was developed from just one week of data collection in 2017. This limited time span did not allow astronomers to see how the ring evolves over time.<\/p>\n

An international team of researchers embarked on a study of this archival data, combining it with the wealth of information developed from the 2017 observations.<\/p>\n

However, the older data is far less extensive than the images seen in 2017. This required researchers to use statistical and geometrical modeling to fill in some gaps in the archival data.<\/p>\n

The analysis revealed the black hole in M 87 behaves exactly as theoretical physics predicted for a black hole<\/a> of 6.5 billion solar masses.<\/p>\n

\u201cDo you realize that if you fall into a black hole, you will see the entire future of the Universe unfold in front of you in a matter of moments and you will emerge into another space-time created by the singularity of the black hole you just fell into?\u201d Neil deGrasse Tyson<\/p>\n<\/blockquote>\n

While the size of the ring remains constant, fine details in the ring, as well as its orientation, change over a period of several years. Studying these changes can help astronomers learn more about the changing shape of the accretion ring surrounding the black hole<\/a>.<\/p>\n
