The first black hole ever photographed is apparently ‘wobbling’

In April 2019, scientists made history by revealing the first ever photo of a supermassive black hole — something that by all accounts, should be unseeable. The Event Horizon telescope collaboration revealed what appeared to be a golden hole, situated in the heart of an elliptical galaxy called Messier 87. Naturally, the photo was quickly compared to everything from the Eye of Sauron to a blurry bagel, because the internet is the internet.

Now, new research published in The Astrophysical Journal shows that when you compile multiple frames together, you can track the black hole’s movement — and it likes to wiggle. Well, more accurately, it rotates.

“Because the flow of matter falling onto a black hole is turbulent, we can see that the ring wobbles with time,” said Maciek Wielgus, the study’s lead author and a radio astronomer at Harvard University.

Using archival data from the past decade — compiled from a combination of stills from the Event Horizon telescope and mathematical models based on the April images — astronomers have been able to get a more detailed idea of the black hole’s nature, with the analysis suggesting that the orientation of the ring isn’t constant…Read more>>
