NGC 7635, aussi appelée la nébuleuse de la bulle, Sharpless 162 ou Caldwell 11, est une nébuleuse à émission (H II) située dans la constellation de Cassiopée. Elle se trouve à proximité de l'amas ouvert Messier 52. La « bulle » est créée par le vent stellaire d'une étoile massive de magnitude 8,7 . La nébuleuse est près d'un nuage moléculaire géant qui contient l'expansion de la nébuleuse de la bulle tandis que lui-même est excité par l'étoile centrale. Elle a été découverte en 1787 par William Herschel. L'étoile centrale (SAO 20575 ou BD + 602522) possèderait une masse estimée à 10-40 masses solaires.
