Chapter 4 discusses how objects in the Universe move. First, the chapter explores the relationship among distance, speed, and time and the concept of lookback time. Next, you will learn how to measure the Doppler Shift and use it to determine the velocities of moving objects. The motions of astronomical objects – their rotations and orbits – are also discussed.

4.0: Moving Through Space Introduction
4.1: Relationship Between Distance, Speed, and Time
Before we can apply the concepts of distance, speed, and time to the Universe, we must understand the specific meaning of each and examine how they are related.
4.2: Measuring Motion - the Doppler Shift
4.3: Astronomical Objects in Motion
4.4: Wrapping It Up 4 - The Andromeda Shift
You will practice measuring lookback time; practice working with spectra , including blue/redshifts and using the velocity formula; You will also put things in context/frame of mind for ages/timescales.
4.5: Mission Report 4 - The Andromeda Shift
