File:NASA Black Hole Visualization Takes Viewers Beyond the Brink (SVS14576 - FlyBy Times Still 04360).jpg

English: Flyby clock comparison. This movie tracks the local time of the falling camera, the time as experienced by a faraway observer (coordinate time), and the maximum blueshift observed. This is the factor by which the frequency of light in the direction of travel is increased. As the video plays, these times increase and diverge, and by the end, local time lags coordinate time by 36 minutes. At 46 seconds, the blueshift reaches 2.34 as the camera's motion peaks at 60% the speed of light.Credit: NASA's Goddard Space Flight Center/J.
