NASA’s Astronomy Picture of the Day

In today's image, we see the Medusa Nebula. This is an example of a planetary nebula which is what will form at the end of the life of a star much like our own Sun.

In today's image, we see the planets Jupiter and Venus as they appeared close together in the sky earlier this month. When two objects pass close together in the sky, we call this a conjunction. Another conjunctions will occur later this year with Venus and Mars.

In today's image, we see the Soul Nebula which is a star forming region in the constellation of Cassiopeia. New stars are forming and are clearing out the gas and dust from the central regions.

In today's image, we see a rainbow that appear to end at a tree off in the distance. The actual position of the rainbow depends on the location of the observer, however. The rainbow is formed when sunlight is reflected and refracted through water droplets left in the atmosphere after a storm which produces a rainbow in the part of the sky opposite to the Sun.

In today's image, we see the moon of Saturn known as Hyperion. It is interesting for the unusual craters on its surface which give it an almost sponge-like appearance. The image was taken by the Cassini spacecraft back in 2005 when it was exploring the ringed planet and its moons.

In today's image, we see the asteroid Bennu which was visited by the OSIRIS-REx spacecraft a couple of years ago. The spacecraft collected a sample of the asteroid which is now on its way back to Earth for more detailed study. This is scheduled to arrive in September of this year. Samples of asteroids like this can give us a look into the material that was present in the early solar system when planets like Earth were forming.

In today's image, we see the Orion Nebula below. This is an emission nebula showing the red glow of hydrogen gas which has been excited. Above is the Running Man Nebula which has a blue color and is a reflection nebula where dust preferentially scatters the blue light from hot stars.

In today's image, we see the asteroid known as Dimorphos just a few seconds before the DART craft impacted into its surface. This was an experiment to see how an asteroid orbit could be changed by an impact as a potential planetary defense measure in the future. It was found that the orbit of Dimorphos was decreased by about half of an hour from its original 12 hour orbit.

In today's image, we see a map of the world showing the brightness of the night sky caused by artificial lighting here on Earth. In may of the more populated areas, the Milky Way galaxy is no longer visible because of the increased sky brightness.
