The Event Horizon Telescope (EHT) recently released a "high-definition" photo of the M87 black hole, which has undergone significant changes compared to the previous one. In 2019, the EHT collaboration released the first black hole photo in human history. The protagonist is the supermassive M87, located in the center of the M87 galaxy, 55 million light-years away from the Earth.
The data behind that photo was collected in 2017, while the latest one uses data from 2018.

Comparing the two photos, you can see thatThe brightest part of the halo around the M87 black hole, which was previously located almost due south, then rotated about 30 degrees counterclockwise and is located at about 5 o'clock.
Such changes are in line with scientists' speculations when the photos were first released in 2019.
The "resolution" of the new photo has not been further improved, and the jet of the black hole has not been captured. However, the direction of the black hole's rotation axis estimated based on the rotation angle of the bright area of the halo is consistent with the direction of the jet observed in other wavebands.
