NASA’s Astronomy Picture of the Day
These podcasts are my discussion of NASA's Astronomy Picture of the Day. These are brief (3-5 minute) audio summaries of the picture posted on NASA's Picture of the Day website: APOD. Video versions of these are available on YouTube. I use these as the introduction to each of my introductory astronomy classes. Students will be able to access them here to review what was discussed in class. I appreciate any comments or suggestions which can be sent to: wagnerastronomy@gmail.com.
