For information about Educational Standards that this feature meets, please visit the DLESE catalogue's entry for the Cosmic Distance Scale: Updates: 02/03/16 Why was this feature written? The Imagine the Universe! "Ask An Astrophysicist " service gets many questions asking why humans do not travel to the nearest star or galaxy - many people do not realize how spectacularly far away the "nearest" astronomical objects are.Ī note to teachers: This product passed the NASA Education Product review in 2010. The number of zeros increase with each zoom, though not at a constant rate. We instead focus on the large number of zeros that are in astronomical distances when we measure them with a familiar unit like the kilometer. This is not, however, an exercise in "powers of 10" - on the contrary, our goal is to show you astronomical distances without scientific notation. This feature will give 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.
