= Bipolar nebula
{wiki=Bipolar_nebula}
The term "bipolar nebula" refers to a type of astronomical nebula characterized by a bipolar structure, meaning it has two lobes or outflows that extend in opposite directions. These nebulae are often associated with the late stages of stellar evolution, particularly with certain types of stars, such as preplanetary nebulae and planetary nebulae. Bipolar nebulae are typically formed when a star undergoes significant changes as it exhausts its nuclear fuel.
