ASTA33 Lab: The rotation curve of the Milky Way
... In this lab, you will use a small, but nevertheless very real radio telescope. It is a very complicated piece of equipment, compared to to a tube with a lens (also known as optical telescope), but you can use it to do amazing science. Indeed, with our small radio telescope you will literally observe ...
