Welcome to Astronomy Cast, the most popular astronomy-related podcast. Just look at what listeners have to say about it:

Astronomy Cast is out of this world! It's hard to believe that it's free! This is an absolute must for any amateur astronomer or anyone interested in astronomy or cosmology. The hosts, Pamela and Fraser, are fun to listen to, extremely knowledgeable, and are able to explain difficult subject matter with great analogies. Bravo!
"Very interesting and almost "easy" for amateurs to listen and understand"

Astronomy is one of the few sciences where amateurs make meaningful contributions to discoveries. Many professional researchers work hand-in-hand with teams of amateurs to make discoveries that just wouldn't be possible without this kind of collaboration. In fact, Pamela regularly relies on dedicated enthusiasts for her data on variable stars.

Not everyone can have a 107-inch scope in their yard, but anyone can have 7x50 binoculars in their glove compartment.
Buying your first telescope can be a nerve-wracking experience filled with buyer's remorse. This week we discuss the basics of purchasing your first binoculars and telescope. What to look for, how to clean older equipment, and how to use it for the first time. Let's make sure your first investment in this wonderful hobby is money well-spent.
