NASA’s Astronomy Picture of the Day

In today's image, we see the spiral galaxy known as M100 - this is an example of what is called a grand design spiral galaxy for its majestic spiral arms. We not the blue and pink color of the spiral arms. The blue is the light of many massive, hot blue stars that have formed within the spiral arms. The pick is the glow of hydrogen gas that is energized by the ultraviolet light from these stars.

In today's image, we see the Leo Triplet - a group of spiral galaxies in the direction of the constellation of Leo the lion. The galaxies appear relatively close to one another in the sky, spanning a distance of only about two full moons. They are actually close together in space as well as they interact with one another causing tidal distortions.

In today's image, we see two galaxy which have recently interacted. We can see how the one galaxy contains material that has been distorted as the gravitational fields of the two galaxies interacted. These interactions also increase the stat formation rate in the galaxy giving rise to the large number of blue stars which color much of these tidal streams.

In today's image, we see the Sun setting at the end of a road. This road runs roughly east-west so the Sun will appear to rise and set at the end of the road on the two equinoxes that occur each year. For this in the Northern Hemisphere, today is the Vernal Equinox or the first day of spring. On this day, the Sun crosses the celestial equator moving into the northern part of the sky. It is also the day where day and night will be of equal length - 12 hours each.

In today's image, we see galaxies in the process of colliding. The collision will allow large gas clouds to merge and compress, causing star formation rates to increase. We see this in the many large, blue star cluster visible around the image. In a few hundred million years, the collision will have finished and we will have just a single, ordinary galaxy left behind.
