Another week, another planet. This time we talk about our own home world: Earth. You might think you know the planet beneath your feet, but it's actually one of the most interesting and dynamic places in the Solar System. Learn about our planet's formation, weather, its changing climate, and life.

Show Notes

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"

    Need transcript!

    I agree with Martin, please furnish the transcript to this episode and to all the others that are lacking!

  3. NightBird Says:

    Yes, please publish those few transcripts. Without them, some of us can't help getting lost in the heaven of Pamelas's voice and missing the celestial events she actually talks about.

    Let's have the transcript, please!
    Note that the text on 80 is the show 71, please correct!
