Duke University is hosting a free course (video lectures) on "Introduction to Astronomy" by Ronen Plesser. Starts Nov 27th. Free to sign up!
In this class, we will be studying, quite literally, everything in the universe. We will start with "classical" astronomy, describing the night sky and organizing what we see as was done in ancient times. We will then embark on a journey, starting here on Earth and progressing outward, to study the Solar system, the Milky Way galaxy, and the wonderful and strange objects we observe in deep space, such as black holes, quasars, and supernovae....
