NASA’s Astronomy Picture of the Day

In today's image, we see the Shark Nebula, which is an example of a dusty nebula in a region of star formation in a molecular cloud. The two brighter area to the left of center are examples of emission nebulae. and the object to the right and slightly above the nebula is a distant galaxy.

In today's image, we see the two innermost large moons of Jupiter - Io and Europa as they orbit around the giant planet. We also see the Great Red Spot, the largest storm in the solar system.

In today's image, we see the two largest satellites of Earth. The largest satellite is the one natural satellite, our own Moon. The next largest satellite is the International Space Station. While they may appear close to gather in the image, they are actually far apart with the ISS being in low Earth orbit, circling Earth every 90 minutes. Our Moon, on the other hand, takes nearly a month to circle Earth once.

In today's image, we see the spectrum of the Sun. When light is passed through a prism or similar device, it is split into its component colors. The lines we see are from different elements allowing us to determine the composition of stars and the Sun. In the 1870s, helium was discovered in the Sun before it was known on Earth.

In today's image, we see the planet Mars and the Beehive Cluster. The Beehive is an open cluster of stars located in the constellation of Cancer. Mars is prominent in the evening sky this month after sunset alone with the planet Venus.

In today's image, we see Pandora's Cluster of galaxies. This is a massive closure resulting from the merger of three galaxy clusters. Much of the mass of this, and other clusters, is in the form of dark matter. Dark matter is completely invisible and only detectable through the gravitational interactions. This is often seen in gravitational lensing when the light from more distant galaxies is distorted as it passes through the cluster.

In today's image, we see part of an emission region where stars are currently being formed. The Elephant's Trunk Nebula to the left and the Caravan below that and to the right. The red glow is due to the emission from Hydrogen gas which will glow red when excited by ultraviolet light from hot stars.

In today's image, we see the galaxy known as M94. This is an example of a ring galaxy which is a relatively unusual type of galaxy. While we know of a tremendous number of galaxy's, the number of ring galaxies is small. The inner ring may have been caused by a recent burst of star formation, but the reason for the outer ring is not currently known.

In today's image, we see an animation of a star consuming one of its planets. The actual event was detected in 2020. And was the first detection of such an event even though we understood that this kind of thing must occur. The animation will show what happened in far more detail than could be directly observed over the vast distance.

In today's image, we see the Triffid Nebula, also known as M20. The three dust lanes across the center of the nebula give it its name. In this we are seeing a region off star formation with the red glow of gas due to emission from hydrogen atoms and the blue of the reflection of light off dust particles around young stars.
