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: © : M. Wielgus, D.

The 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.

A new analysis of data from that study sheds additional light on the lightless object — The ring is glittering.

“The results announced in 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,” states Maciek Wielgus, astronomer at Harvard University. …
