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: [email protected].

In today's image, we see the reflection nebula known as VdB 31. The reflection nebula is caused by the scattering of light off of dust grains around a hot star. We can also see some of the dark dust …
In today's image, we see a video showing the asteroid Bennu as it rotates out in space. A sample of this was returned to Earth and has been found to contain amino acids which are the building blocks …
In today's image, we see two nebulae in a star forming region which are whimsically known as the Spider Nebula and the Fly Nebula.
