NASA’s Astronomy Picture of the Day

In today's image, we see the nebula known as the Ghost Nebula. Here we see a dusty area of space in the direction of the constellation of Cepheus. The darker dusty area are where stars are continuing to form. The less dense area are where light is reflected off of the dust grains.

In today's image, we see a partial eclipse of the Moon that just occurred with the full moon. A lunar eclipse occurs when our Moon passes into Earth's shadow and part of the Moon does not receive direct sunlight. In this case it is the portion to the lower right that is within Earth's shadow.

In today's image, we see the region around the bright star Gamma Cas, one of the brighter stars in the constellation of Cassiopeia. The red glow in an emission nebula caused by emission from hydrogen gas excited by the ultraviolet light from the star. The blue is reflection of the light off of dust grains in the nebula.

In today's image, we see Comet Encke - a periodic comet that returns to the inner solar system every 3.3 years and made its closest approach to the Sun just a few days ago. On the other side of the image, we see an emission nebula and a much greater distance which is in the process of forming new stars.

In today's image, we see two Orionid meteors in the sky. The Orionid meteor shower is one of two that occurs each year that is associated with debris left behind by Halley's Comet. The cluster of stars off to the right is the Pleiades star cluster.

In today's image, we see a video watching the Sun set below the horizon. We will note the distortions around the limb of the Sun caused by Earth's atmosphere. We will also note the green (and blue) colors around the limb of the Sun and the green/blue light that briefly remains after the Sun has set.

In today's image, we see a pair of galaxies in the process of merging - a process which can take a billion years or more. Galaxy mergers are quire common and are how galaxies have grown in size from the small galaxies created after the Big Bang to the large spiral and elliptical galaxies we see today.

In today's image, we see an image of the moon of Jupiter known as Io as taken recently by the Juno spacecraft orbiting Jupiter. Io is the most volcanically active object in our solar system because of the gravitational interactions between it and Jupiter and some of the other moons. Closer images are expected over the next few months as Juno will make a couple of even closer passes to this moon.

In today's image, we see an aurora over Northern Canada in this image taken a decade ago. Perhaps you will see the apparition of a ghostly figure in the aurora as your mind try to put some order to the random patterns in the sky.

In today's image, we see all of the quarter moon of the year 2022. These include both the first quarter moons and third quarter moons of the year. We can tell this by the side that it's illuminated. The first quarter moon will be illuminated on the right side and the third quarter moon illuminated on the left side.
