In today's image, we see the spiral galaxy known as M83. This is an example of a spiral galaxy and shows the signs of extensive star formation, including the blue color of the spiral arms from the hot stars that have formed there to the red "rubies" which dot the spiral arms and are glowing hydrogen gas, excited by these stars.

In today's image, we see the Oyster Star Cluster also known as NGC 602. This is a young star cluster and parts of it are still forming.

In today's image, we see a spiral which shows the history of the entire universe in one spiral. It starts with the Big Bang at the center and then highlights 13.8 billion years of histories you track around the spiral. My podcasts are available in video form through this YouTube Channel.

In today's image, we see the path of the full moon across the sky from about one week ago. This is the summer solstice moon which is very low in the sky as it is opposite to the Sun which is highest in the summer. It was also at the most extreme low for the 18.6 year lunar cycle which brings it even closer to the horizon. My podcasts are available in video form through this YouTube Channel.

In today's image, we see a comet. In many ways, this is much like Halley's Comet. Olber's Comet orbits the Sun just a little faster than Halley's completing an orbit once every 68 years. In two days, it will reach its closest approach to the Sun and is visible through a pair of binoculars. My podcasts are available in video form through this YouTube Channel.

In today's image, we see the galaxy known as JADES-GS-z14-0. This galaxy, recent imaged by the James Webb Space telescope is now known to be the most distant galaxy ever observed. The galaxy is seen about 300 million years after the Big Bang, just a fraction of the age of the universe. My podcasts are available in video form through this YouTube Channel.

In today's image, we see the planet Saturn as imaged by the Cassini spacecraft back in 2005. We can see the shadows of the rings against the upper part of Saturn. We can also see the blue color (slightly enhanced) caused by scattering from molecules in the atmosphere of Saturn. My podcasts are available in video form through this YouTube Channel.

In today's image, we see the spiral galaxy known as NGC 1546 as imaged by the Hubble Space Telescope just a week ago. Hubble is using a new pointing system to help keep the telescope pointed accurately even as the accuracy of its gyroscopes degrade over time.

In today's image, we see the dog, Sandy by the gate off to the right. Up in the sky, we see the full moon from April. Ice crystals in the atmosphere form the halo around the Sun. There is another full moon just a day or so from now. Today is the summer solstice when the Sun reaches its highest point above the celestial equator.
