Telescopes unite in unprecedented observations of famous black hole

ScienceDaily : Long article here


The immense gravitational pull of a supermassive black hole can power jets of particles that travel at almost the speed of light across vast distances. M87's jets produce light spanning the entire electromagnetic spectrum, from radio waves to visible light to gamma rays. This pattern is different for each black hole. Identifying this pattern gives crucial insight into a black hole's properties -- for example, its spin and energy output -- but is a challenge because the pattern changes with time.
