This unique original infographic explains in detail the appearance of an accreting black hole. Side and top schemes show the path of the light rays bent by gravity and the trayectory from each part of the black hole to the observers POV.

Black Holes in the Milky Way
(*system)
An infographic showing a scaled representation of the 23 confirmed black holes within our galactic vicinity. 22 stellar-mass black holes and one central supermassive black hole are presented to scale in a perspective view as seen from Earth. A fact sheet accompanies these adorable creatures so you can learn about their different personalities.
This is a remix/derivative of NASA’s Black Hole Orrery. Black hole images and temperature maps created by: NASA’s Goddard Space Flight Center/Andrew J Christensen. Factsheets and overall poster composition by Pablo C. Budassi in September 2023.
