PK 329-02.2: Menzel 2
PK 329-02.2, also called Menzel 2, is a planetary nebula located towards the constellation Norma. The nebula surrounds two stars, one (lower left) the companion of the central star (upper right).
Planetary nebula form when medium sized stars- about the mass of our Sun- run out of fuel. After expanding into a red giant, the star collapses into a white dwarf, emitting its outer layers. These emissions can be very irregular and shaped by surrounding material and objects, creating intricate, glowing nebulae like Menzel 2.
