Astronomy Lesson 04_09: Spectroscopic Parallax
All of astrophysics depends on knowing accurate distances. Here, we see how knowing the distance to a well-studied, nearby star cluster can help us begin to determine the size scale of the Universe. We see how parallaxes, and brightntesses in standard filters can get us all the way out to extremely far distances, and teach us about the nature of those distant places.
