“We’re really starting to see orbits, we’re seeing right down next to the black hole and probing this exotic environment.” “This is the kitchen sink of physics, right? Everything is in there,” says McGill University’s Daryl Haggard, who helped coordinate the multiwavelength observations. It describes a more complete view of the supermassive black hole and its massive jet, letting scientists take a good look at how magnetic fields, particles, gravity, and radiation interact within the vicinity of a supermassive black hole on multiple scales. The report, which appears today in The Astrophysical Journal, includes data from 19 Earth- and space-based observatories, and is authored by more than 750 scientists. Two years later, the international team that delivered the astounding image, along with additional partners, has published the results of a 2017 observing campaign that simultaneously scrutinized the host galaxy, Messier 87, in multiple wavelengths. Using an array called the Event Horizon Telescope (EHT), scientists harnessed radio waves to capture a mugshot of that black hole, offering our first-ever look at the extreme environment near its edge in 2019. In the heart of a gargantuan galaxy 55 million light-years away, a black hole with the heft of 6.5 billion suns is hurling a fountain of matter into the cosmos at near light-speed.
