Well done and instructional video, as are some that show up after that one. Seeing something like that in an interesting video always makes it easier to understand and remember.

When looking for large objects, consider this from a link from ECN News: Astronomers Determine Precise Mass of a Giant Black Hole

Astronomers from the University of California, Irvine and other universities have derived a highly precise measurement of the mass of a black hole at the center of a nearby giant elliptical galaxy. Working with high-resolution data from the Atacama Large Millimeter/submillimeter Array in Chile, the scientists were able to determine the speed of a disk of cold molecular gas and dust orbiting the supermassive black hole at the heart of galaxy NGC 1332. From there, they calculated the black hole’s mass to be 660 million times greater than that of the Sun.
