NGC7635, Sh2-157, The Bubble and the Lobster's Claw nebulae
Take a look at the updated version of my Bubble and Lobster Claw nebulae photo!
The Bubble nebula (NGC 7635) is a large, spherical cloud of gas and dust that has been blown out by the strong stellar wind of a massive central star. This beautiful object is located in the constellation Cassiopeia and it is one of the most popular objects for astrophotographers. The bright blue bubble is created by the intense radiation from a massive hot star. The outer parts of the bubble are created by the shockwaves of material being pushed away from the central star.
The Lobster's Claw Nebula (Sh2-157) is a bright, red cloud of gas and dust that is being sculpted by the intense radiation from a nearby hot, young star. This object is located in the constellation Cassiopeia and it is also a popular target for astrophotographers. The bright red color of the nebula is caused by the intense radiation of the hot star which excites the hydrogen gas in the nebula, making it glow. The shape of the nebula is created by the intense stellar winds and radiation from the hot star which are blowing away the surrounding material and shaping it into its unique claw-like appearance.
