Prof. Larkin is very knowledgeable in this subject. The class covers some topics like special relativity and general relativity that can be hard to fully grasp, but Prof. Larkin does a very good job at explaining it. He is also available for office hours and is always willing to answer questions. I've been interested in astronomy since I was little, and although I'm not in a STEM major, I found the class very fun. I honestly loved it and the work load was super manageable; this is a great easy science GE!
