In today's image, we see the galaxy known as M 106. This is a specific type of spiral galaxy known as a Seyfert Galaxy. This is what is known as an active galaxy which emits more energy from its core than an ordinary spiral galaxy. My podcasts are available in video form through this YouTube Channel.

In today's image, we see an image from the annular solar eclipse from this past week. Here, the Moon passes in front of the Sun, but the Moon appears slightly smaller than the Sun because of its distance and is unable to completely block out the Sun's light. This leaves a ring or annulus around the Sun. My podcasts are available in video form through this YouTube Channel. This Podcast is an authorized New Media Mirror Site for APOD.

In today's image, we see comet Tsuchinshan-ATLAS in the sky. The comet is currently very close to the Sun, but will likely be bright enough to be seen with the naked eye as it moves away from the Sun and is visible in the western sky after sunset.

In today's image, we see the great comet of 2007, Comet McNaught. The comet was one of the brightest to have been seen in several decades. Now, we look for Comet Tsuchinshan-ATLAS which is brightening in the sky and may become a prominent comet over the next couple of weeks.

In today's image, we see an object which is not a comet, but is actually a planetary nebula. This type of nebula is what forms at the end of the life of a star much like our own Sun as the core compacts dow to a white dwarf star and the outer layers expand out into space.

In today's image, we see the comet known as Tsuchinshan-ATLAS as it is visible in the sky just as the moon is barely rising over the horizon. The comet has been brightening and may be a nice sight in the sky as it makes its closest approach to Earth in a little over a week.

In today's image, we see a partial solar eclipse that occurred yesterday and was visible over parts of the South Pacific and South Atlantic oceans. Thursday annular eclipse was seen primarily over the oceans, but the partial phase was visible from Hawaii as well as parts of South America.

In today's image, we see what is known as Porphyrion which is the longest known jet from a black hole, stretching 23 million light years from end to end. This is larger than the distances to many galaxies, which shows how jets like these may affect galactic neighbors and not just the galaxy itself.

In today's image, we see the comet known as Tsuchinshan-ATLAS as seen from a drone hovering about the clouds in Mexico. While the comet it currently at the edge of naked-eye visibility, it may brighten over the coming weeks to make it even brighter and visible without the aid of binoculars or a telescope.

In today's image, we see images of 20 different galaxies, each of these seen to have streams of stars around it. The streams are caused by the larger galaxy which is consuming a smaller galaxy and tearing it apart with its tidal forces. My podcasts are available in video form through this YouTube Channel.

In today's image, we see the comet know as A3 as it rises above the horizon over Australia. Over the coming month, the comet will brighten, but by what amount is uncertain so we do not know exactly how bright this comet will become.

In today's image, we see comet Tsuchinsan-ATLAS which will make its closest approach to Sun later the week and its closest approach to Earth next month. It may brighten enough to be visible with the naked eye, but it is extremely difficult to predict the future brightness of a comet.

In today's image, we see an image of our Sun setting along the streets of Chicago. Because the image was taken on the equinox, the Sun will rise directly in the East and set directly in the west, lining up with streets in cities that are set up in an East-West grid like this one.

In today's image, we see the dusty area in the sky in the constellation of Cepheus. You may recognize the shape, which somewhat resembles a seahorse.
