NGC 7635, known as the Bubble Nebula, is an emission nebula—an H II region—located in the constellation Cassiopeia. It formed due to the stellar wind from the central star, which sculpts the surrounding gas.
Its distinctive spherical shape marks the boundary between the intense flow of particles emitted by the star and the dense material surrounding it.
