description Mz 2 (Menzel 2) Overview
Mz 2, also known as Menzel 2, is a planetary nebula in the constellation Norma. It is the glowing shell of ionized gas expelled by a star that has reached the late stages of stellar evolution, rather than a planet or a star-forming nebula. Mz 2 is associated with a bipolar form, in which material is distributed into two opposing lobes or outflows. Astronomers study such structures to understand how asymmetry develops in planetary nebulae.
