The Bubble Nebula, designated NGC 7635, is a stunning celestial wonder located in the constellation Cassiopeia. This breathtaking emission nebula is a region of active star formation, where massive stars at the center emit intense ultraviolet radiation, causing the surrounding gas to glow brilliantly. What makes the Bubble Nebula particularly captivating is its spherical, bubble-like structure, created by the powerful stellar winds and radiation from a central massive star known as BD+60°2522. This stellar wind compresses the surrounding interstellar material, sculpting the gas and dust into a shell-like form. The Bubble Nebula is a visual testament to the dynamic interplay between massive stars and the cosmos, offering astronomers a glimpse into the ongoing birth and evolution of stars in our Milky Way galaxy.

Planetary nebula KjPn 8 (PN G112.5-00.1, K3-89) and Bubble Nebula (NGC7635) in the constellation Cassiopeia.KjPn 8 (PN G112.5-00.1, K3-89) is a bipolar planetary nebula which was discovered by M.A.Kazaryan and Eh.S.Parsamyan in 1971 and independently by Kohoutek in 1972. It is one of the strangest and possibly most unique planetary nebulae in the sky. In my image, we see it on the left side of the frame below the center. Planetary nebula consists of a compact red core (apparent size is about 3–4 arcsec in diameter) surounded by a huge bipolar lobe structure that measures 12x5 arcminutes. There is the possibility that the two separate structures are two separate planetary nebulae formed from both members of a binary star system moving onto the planetary nebula phase within a few thousand years of each other.
