M87* Black hole. First ever image along with the magnetic field
Well this is not a like a photo taken from a telescope direct. But by collecting the raw data, radio waves from the accretion disk around the black hole, they were able to reconstruct the raw data into a image!
Those lines depicts the strength of magnetic field created by the plasma, the temperature might reach up to tens of billions of Kelvin.
Remember that this was not collected from a single telescope. They used global network of radio telescopes in our world targeting this M87* black hole stitching all the raw data into a reconstructed visual image
