Galaxies in Motion - SOLD OUT

Although it may be counterintuitive, our Universe is an incredibly dynamic place, ever in motion and ever changing. In fact, the study of how objects move is a key part of how astronomers build an understanding of their nature. However, the timescales involved in these motions are typically very long, particularly for studies of distant galaxies. So how do astronomers measure the motions of galaxies if changes take such a long time? And what do these motions tell us about how they were formed and how they change with time?
