NASA’s Astronomy Picture of the Day

In today's image, we see the year 2025 in sunspots. The central image shows the sunspots for the entire year as measured by the Solar Dynamics Observatory. The individual images around the center break down the sunspots by the individual months of the year. My podcasts are available in video form through this YouTube Channel .

In today's image, we see the active sunspot region 4366 as visible on the face of the Sun.

In today's image, we see the supernova remnant Cassiopeia A. This would have been seen to explode back in the mid-late 1600s but was never definitively observed - perhaps because of excess dust in the region.

In today's image, we see the central galaxy in the Perseus Cluster of galaxies, NGC 1275. This galaxy shows long structures that come out of it, likely due to energy produced by the central black hole of the galaxy. My podcasts are available in video form through this YouTube Channel .

In today's image, we see the Red Spider Planetary Nebula - this is what forms at the end of the life of a star like our Sun - at least it would if our star were part of a binary system. In reality, our Sun will form a much simpler planetary nebula. 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 part of the Orion star forming region focusing on the Running Man Nebula. Here we see blue reflection nebulae, red emission nebulae, and the dark brown of dusty nebulae.

In today's image, we see the Artemis I spacecraft as it reached its greatest distance from Earth in November of 2022. Artemis II is scheduled for launch next month and will take astronauts back around the Moon for the first time since 1972. My podcasts are available in video form through this YouTube Channel .

In today's image, we see a star forming region in the constellation of Perseus. Within, we see a blue reflection nebula, plus the red color of interstellar gas excited by the jets of material emitted by young stars as they form.

In today's image, we see the barred spiral galaxy known by its catalog designation NGC 2442. The galaxy is a bit distorted, likely because it is interacting with another galaxy just off the frame to the upper right. My podcasts are available in video form through this YouTube Channel .

In today's image, we see the region around the constellation of Orion in a long exposure taken using a camera looking at a large region of the sky. The long exposure brings out details that would be invisible to the unaided eye. My podcasts are available in video form through this YouTube Channel .

In today's image, we see the galaxy known as NGC 55. This image consists of 50 hours of exposure, looking just at the light emitted by hydrogen and oxygen. This narrow band image allows us to emphasize the nebulae in the galaxy. My podcasts are available in video form through this YouTube Channel .

In today's image, we see the Earth about to set behind the limb of the Moon as seen from the Orion spacecraft back in 2022. This was part of the Artemis I mission.

In today's image, we see the barred spiral galaxy known as NGC 1365. This is a nearby barred spiral galaxy, much like our own Milky Way. It is being observed in the infrared which allows a better focus on the dust in the spiral arms of the galaxy. My podcasts are available in video form through this YouTube Channel .
