The black hole images here are rendered live by tracing light rays through curved spacetime, including gravitational lensing, Doppler beaming and gravitational redshift. Sizes and colours are tuned so you can see them, but the bending of light is real. Star map: NASA/Goddard Space Flight Center Scientific Visualization Studio, Deep Star Maps 2020.
