Division Nebula

== Overview ==
The Division Nebula is a emission bipolar planetary nebula located in the constellation Aquila, it is about 35.76 light-years from Earth. It is listed as Keesar 1 in the Keesar Catalog and is also known as the Dual Jet Nebula (not to be confused with the Twin Jet Nebula).
== Structure ==
The Division Nebula looks to contain two elongated tubular structures, each with a diameter of 4.27 light years and a slight oblate spheriod in the center. It is bipolar. This type of structure is the logical outcome of a bipolar model.
== Formation ==
The hot core of a star that reached the end of its main-sequence life cycle, ejected most of its outer layers, became a red giant, and is now contracting into a white dwarf is the primary component of the central binary. It is thought to have started out as a sun-like star. The binary's second, smaller star orbits very closely and may have been engulfed by the other's expanding stellar atmosphere, resulting in the nebula structure we see today.
