What you see in this unique picture are Moondogs. You are probably wondering two things. One that I did not say Sundogs and two, dog what? Well, usually during the morning in the winter season the trajectory of the sunlight through hexagonal ice crystals that are in the sky bend 22 degrees and cause Sundogs. The same thing happens with Moondogs except it is the moon's light that bends. Also, these Moondogs are commonly located in the opposite direction in the sky compared to the Sundogs who are on each side of the Sun. They are called Moon-dogs because it refers to the word follow, therefore, Moondogs follow the Moon just like Sundogs follow the Sun. These Moondogs are usually faint so it is rare to catch a view at one of these beauties.
PS. If you can see the white dot next to the bright white glow that is on the right, then you are looking at our friend Jupiter!

As you can tell, there are multiple clusters and stars gathering around NGC 7822. Thanks to NASA's Wide Field Infrared Survey Explorer this picture can be captures in the location of the constellation Cepheus. The bright orange cluster you can see in the picture has a great amount of powerful energetic radiation sending strong winds.
