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 clouds in the atmosphere of Mars as viewed by the Perseverance rover on Mars earlier this year. The clouds are composed of ice crystals since the atmospheric pressure on Mars…
In today's image, we see the nearby spiral galaxy known as NGC 300. This galaxy is close enough that we can resolve individual stars in its spiral arms, instead of just seeing them as a blue glow.

In today's image, we see the average color of the universe if the light from the galaxies were to be smeared out over the entire sky. The color changes over time and was slightly bluer in the past an…
In today's image, we see an extreme panoramic view from the French Alps. Taken on two different days, we see the scene in winter in the lower part of the image and summer in the upper part.

In today's image, we see a meteor and Comet Tsuchinshan-ATLAS which was visible a couple of months ago. While the meteor was only visible for a fraction of a second, the comet was visible in the sky …
In today's image, we see the Sombrero Galaxy in visible light from the Hubble Space Telescope and in infrared light from the James Webb Space Telescope.

In today's image, we see the Horsehead Nebula in Orion. This is a dark nebula, which blocks out the light from behind it. Within the nebula, new stars are forming which will eventually destroy the ne…
In today's image, we see a video clip that will show a trip through the star clouds of the Milky Way and into the central regions of the galaxy itself.

In today's image, we see what are known as undulatus clouds appearing to converge over the telescopes domes on the mountaintop. These are clouds caused by the air currents in Earth atmosphere which g…
In today's image, we see part of what is known as the Pacman Nebula. This is a star forming region, with a newly formed cluster of stars at the center. Those stars are eroding away the material aroun…
In today's image, we see a parabolic outflow from a protostar. This star, is not actually a star, but it a star in the later stages of formation, before it has achieved sufficient temperatures to sta…
In today's image, we see the dwarf planet Pluto as imaged by the New Horizons spacecraft back in July of 2015. Here, we are looking back at Pluto, shortly after the craft passed it, giving us a view …
In today's image, we see the Surveyor 3 spacecraft in the foreground as it is being visited by the astronauts from the Apollo 12 mission. The Apollo 12 lunar module is visible off in the distance. Th…
In today's image, we see the young star cluster, IC 248 as well as Barnard 3, a dark nebula surrounded by a red emission nebula. All of these are related to the young stars currently forming in the r…
