The Collaboration that Brought you the First Image of a Black Hole Just Released Photos of its Massive Jet

Recently published data from the Event Horizon Telescope (EHT) of the galaxy Messier 87 facilitate new insights into the direct environment of the central supermassive black hole. Measured differences in the radio light on different spatial scales can be explained by the presence of an as of yet undetected jet at frequencies of 230 Gigahertz at spatial scales comparable to the size of the black hole. The most likely location of the jet base is determined through detailed modeling. from Universe Today https://ift.tt/fPLtzAa via IFTTT
