Astronomy Cast

From Frasier Cain, publisher of Universe Today, and his guest host Dr. Pamela Gay, who will unperturbedly mispronounce at least one totally ordinary word in every episode.

I've been listening since 2010 when I lived at the Allen Telescope Array in northern California, where I discovered that I can understand science and am not inherently limited in my ability to learn things. Astronomy Cast is nicely organized: single topic, fairly deeply explored and usually just about 30 minutes.
