Key takeaways
A description of redshift is in a spectrum.
An analysis of how we can tell if a galaxy is moving away or towards us by its redshift or blueshift.
A discussion of how redshift has led us to the conclusion that the Universe is expanding.
Laura LewisHost: Laura studied at Royal Holloway University of London and the Open University. She is passionate about science communication and has presented talks about Exoplanets at Oxford University and Imperial College London.

What do you know about the astronomical phenomenon RedShift? In this class, we will look at this fascinating subject  and how it has led us to understand that the universe is expanding. Spectroscopy and the explanation of redshift will be discussed. We will also investigate how the amount of redshift can tell us how fast an object is moving away from us and how far away it is.  

Join Laura in this fascinating class to discuss all thing RedShift.
