|The Cosmic Distance Scale|
This resource gives an impression of how immense our Universe is by employing a method used many times in "Power of 10" films - that is, starting with an image of the Earth and then zooming out towards the furthest visible reaches of our Universe. This is not, however, an exercise in "powers of 10" - on the contrary, the goal is to show astronomical distances without scientific notation. It focuses on the large number of zeros that are in astronomical distances which are then measured with a familiar unit like the kilometer. The number of zeros increase with each zoom, though not at a constant rate. This resource was written because many people do not realize how spectacularly far away the "nearest" astronomical objects are.
