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 multiple images of our Moon in a frame. If you look from a greater distance, or look at the smaller images, you will see an image of Leonardo da Vinci's famous Mona Lisa pain…
In today's image, we see the red and green aurora in Earth's upper atmosphere caused by charged particles from the Sun exciting oxygen atoms.

In today's image, we see a young star cluster as imaged by the James Webb Space Telescope. Here we can look for lower mass stars and brown dwarf stars which emit primarily the infrared light which th…
In today's image, we see a number of different objects in the sky over the Tatra Mountains. This includes our Milky Way, including many stars and nebulae which are part of our galaxy and some meteors…
In today's image, we see the region around the constellation of Orion. This includes the Horsehead Nebula, which is close to the belt of Orion and the Orion Nebula, which is part of Orion's sword. In…
In today's image, we see an image of the planet Mars from space. Here we see one of the moon - Phobos as well as craters and volcanos on the surface of Mars.

In today's image, we see the spiral galaxy known as M31 or more popularly known as the Andromeda Galaxy. This is the nearest large spiral galaxy to our own Milky Way.

In today's image, we see the small moon of Mars, known as Deimos. This moon is likely a captured asteroid that happened to wander into the gravitational field of Mars and become captured. Deimos was …
In today's image, we see the planet Neptune as imaged by the James Webb Space Telescope. This is the first imaging of the rings of Neptune since the Voyager 2 craft flew by the ice giant in 1989. The…
In today's image, we see the nearby spiral galaxy known as NGC 247. In addition, there are many other galaxies in the image, including four in a straight line slightly below and to the left of the ch…
In today's image, we see a portion of the Veil Supernova remnant known as the Bat Nebula. This is some of the debris left behind by a star which exploded long ago and has been expelled out into the i…
In today's image, we see the third quarter moon toward the bottom of the image and the Pleiades star cluster to the right.

In today's image, we see our moon as a thin, waning crescent. A thin cloud in Earth's atmosphere happens to be passing in front of our Moon, giving it a resemblance to the planet Saturn.

In today's image, we see the Galaxy group containing the spiral galaxy known as NGC 7771. The two larger spiral galaxies here are interacting and will eventually merge in to a single larger galaxy. T…
In today's image, we see the region around the South Pole of our Moon. The region is very heavily cratered. We can see a number of older craters which are becoming quite worn over billions of years a…
In today's image, we see the star forming region known as Messier 17. This is essentially a factory where stars are being created from the gas and dust in space, as the materials are pulled together …
In today's image, we see the Tulip Nebula, an emission nebula located in the constellation of Cygnus. Also in the image is the black hole known as Cygnus X-1. This is one of the closer black holes to…
In today's image, we see our moon passing in front of Saturn in what is called an occultation or eclipse. Because of the positioning, this will occur every month for the rest of the year and can be s…
In today's image, we see a video clip showing a number of the Perseid meteors from the shower in 2023. The meteors are small bits of a comet, left behind in its orbit, which are vaporized when it str…
