SH2-313 a.k.a Abell 35

SH2-313 a.k.a Abell 35, a planetary nebula in Hydra ~521 ly away. One of the oldest planetary nebulas similar in size to the helix nebula.

The central binary star system, with one of them being a white dwarf, is responsible for the nebula, and their movement together through the nebula produces the bow shock as seen in the center. LoTr 1 and LoTr 2 are only two other known planetary nebula believed to have a binary system. The central binary system is constantly studied as it presents challenges to theories of binary star systems evolution.
