Course: The Known Universe
with Chris Graney (Jefferson Community & Technical College – JCTC)
WEEK 1: INTRODUCTION
“book” (Graney’s class notes) for the class is The Known Universe: Discovering the Science of Astronomy through the
History of Astronomy. The library is providing this for free. Please bring your library-provided binder
each week for the next free installment!
If you want the whole book at once you can get (not at all for free) a
hardback from the JCTC Southwest Campus bookstore,
a paperback from Destinations
Booksellers in New Albany, or from the printer, Lulu.
for telescopes recommended for beginning students who take JCTC’s AST 195
lab. For MyLibraryU participants I
recommend the less expensive Orion Observer 60mm and 70mm refractors.

Opening scene in movie “Contact” – full of science errors, but illustrates the idea of SETI that signals from Earth can be detected by listeners in space, and that listeners at further and further distances from Earth will hear signals from further back in the Earth’s past – click here. Major errors include that the time delay is exaggerated too much (you would hear signals from a few hours ago at Jupiter, not from years ago) and the asteroids are far too densely packed.
