Part B: Messier 87 (M87) You might remember the first *real* image of a supermassive black hole that has ever been achieved, released by the Event Horizon Telescope Collaboration in 2017 (see image to the right). Its mass was measured to be approximately 6 x 10° times the Sun's mass (1000 times more massive than Sagittarius A*!) Image credit: Event Horizon Telescope Collaboration 8. Part a) Do the same calculation as Question 6 & 7, except now multiply the sun's mass by 6 x 10° before plugging it in to the Schwarzschild radius equation. Then divide the number by 1 AU in meters (Again just submit your answer, do not submit the unit AU). Part b) How does the radius of M87 compare to the radius of Sagittarius A*? (Divide the radius of M87 by the radius of Sagittarius A*.)
