Watch the Sky

Each lab class will have a session scheduled in the Rauch Planetarium to help you learn how the sky changes hour by hour and with the seasons. In another session you will learn about the bright stars, and the planets that are currently visible. It will help if you work on this with a star chart of your own, such as you might �nd in an astronomy book, or in one of these free resources:

Weekly guide and news

Beautiful planetarium software for your computer

If want to pursue this and learn the night sky well, you should consider getting a plani-sphere starfi�nder. This is a rotating map of the sky that will show you how it appears on any date and time. Inexpensive ones may be available from a bookstore or the Planetarium. Stellarium is a desktop planetarium that displays the sky in a photo-realistic view. It is not a static map, but a dynamic moving picture of the sky as the Earth's rotation brings an ever changing view past you. It is a very good way to prepare for this lab, or to use after your lab to learn more.
