NASA’s Astronomy Picture of the Day

In today's image, we see a large, dense galaxy cluster known as the Coma Cluster. The cluster contains thousands of galaxies and is so large that it can take light millions of years to travel across the cluster.

In today's image, we see the comet known as Pons-Brooks. This comet returns to the inner solar system every 71 years and has been observed since the 14th century. It is currently visible with the aid of a telescope or binoculars and may brighten enough to be visible to the naked eye on April 8 when it may be possible to view it during the total solar eclipse that occurs that day.

In today's image, we see a video where the tones the sound are used to represent different colors in the image. The red colors are represented by the lower tones while the blue is represented by the lower tones and the green, the middle tones. This is a way of representing the image in a different way so it can be "seen" even by one who can not see the image directly.

In today's image, we see the shadow of our Moon as cast on the Earth during the total solar eclipse from 1999. The very center region of this shadow will be the area that sees a total solar eclipse with the Sun's light completely blocked by the Moon. The outer areas of the shadow will see a partial solar eclipse and beyond that, no eclipse will be seen at all.

In today's image, we see the region around the landing site of the fictional Ares 3 craft which was the basis of the novel: The Martian in which an astronaut is stranded on the surface of Mars. The image is taken by the Mars Reconnaissance Orbiter showing detail of craters in this region of Mars.

In today's image, we see the planet Mars with its moon, Phobos just appearing in multiple images off the left-hand side. Phobos is an unusual moon in that it orbits so close to Mars that it would actually appear to rise in the west and set in the east and would do this three times each day! It is also known at the doomed moon as it is in such a low orbit, it will eventually be destroyed by today forces of Mars.

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 an image of Comet Pons-Brooks. The coma is highlighted to show the swirling pattern around it. It is thought this might be caused by the rotation of the nucleus of the comet as material is vaporized of its surface by the energy of the Sun.
