Caldwell 55 • NGC 7009 • Saturn Nebula

Caldwell 55 – NGC 7009

Caldwell 55, known as the Saturn Nebula, is a bright planetary nebula in the constellation Aquarius. Its distinctive appearance, with extended ansae resembling the rings of Saturn, makes it one of the most recognizable planetary nebulae. The nebula is illuminated by a hot central star that is shedding its outer layers as it evolves toward the white dwarf stage.
