Astronomy mysteries

I enjoy listening to podcasts while gardening or whenever, and one of the podcasts I really enjoy is Astronomy Cast. They recently had a series of podcasts on mysteries in astronomy that I found fascinating, could be a great resource for someone out there.

• Ep. 174: Mysteries of the Solar System, Part 1
• Ep. 175: Mysteries of the Solar System, Part 2
• Ep. 176: Mysteries of the Milky Way, Part 1
• Ep. 177: Mysteries of the Milky Way, Part 2
• Ep. 178: Mysteries of the Universe, Part 1
• Ep. 179: Mysteries of the Universe, Part 2
