The movie above (refresh the page to restart) shows large changes in brightness of the variable star V404 Cygni over the course of 3.5 hours in June 23, 2015, based on images taken at the RIT Observatory. Our measurements of this star over several nights were combined with those from 25 other observatories, as well as 2 orbiting telescopes, to study the flow of gas around a black hole.

To learn more, read a basic explanation of the project. Please do read the additional resources listed at the end of the document for more details. If you're really gung-ho, you can find the technical version published in Kimura et al., Nature, 529, 54 (2016)
