Rho Ophiuchi Nebula by Lee Buck

The Rho Ophiuchus Nebula Complex (IC4604) and the surrounding area lies within the Ophiuchus Constellation, and is one of the most interesting and beautiful areas in the entire sky.

Featuring the bright star Antares, the Ophiuchi Triple Star and surrounding IC4604 Reflection Nebula, M4 Globular Cluster, and the smaller NGC 6144 Globular Cluster, as well as various dark nebula, this area holds something of interest for any astronomer or deep space imager.

The beautiful blue IC 4604 reflection nebula surrounding the Rho Ophiuchi Triple Star is one of the standout features in this area. It is a result of interstellar dust that is illuminated by nearby stars.

NGC 7635: Bubble Nebula

The Bubble Nebula is located 7,800 light-years from Earth towards the constellation Cassiopeia.

NGC 7635 is surrounded by a vast HII molecular cloud that glows red as hydrogen atoms are ionized. Young stars are forming in some of the globules depicted in this image. These globules form as parts of the molecular cloud collapse and continue to contract under their own gravitational force. — Ryan Hannahoe and Salvatore Grasso

V838 Mon by Delio Tolivia Cadrecha

V838 Monocerotis (V838 Mon) is a red variable star in the constellation Monoceros about 20,000 light years (6 kpc) from the Sun.

The previously unknown star was observed in early 2002 experiencing a major outburst, and was possibly one of the largest known stars for a short period following the outburst. Originally believed to be a typical nova eruption, it was then realized to be something completely different.

The reason for the outburst is still uncertain, but several conjectures have been put forward, including an eruption related to stellar death processes and a merger of a binary star or planets. [**]
