A bipolar nebula is a type of nebula characterized by two lobes either side of a central star. About 10-20% of planetary nebulae are bipolar. [2] Formation
NGC 6302 (also known as the Bug Nebula, Butterfly Nebula, or Caldwell 69) is a bipolar planetary nebula in the constellation Scorpius.The structure in the nebula is among the most complex ever seen in planetary nebulae.
Mz 3 (Menzel 3) is a young bipolar planetary nebula (PN) in the constellation Norma that is composed of a bright core and four distinct high-velocity outflows that have been named lobes, columns, rays, and chakram.
Minkowski 2-9, abbreviated M2-9 (also known as Minkowski's Butterfly, Twin Jet Nebula, the Wings of a Butterfly Nebula, or just Butterfly Nebula) is a planetary nebula that was discovered by Rudolph Minkowski in 1947. It is located about 2,100 light-years away from Earth in the direction of the constellation Ophiuchus.
M1-63 (catalogued as VV 209, IRAS 18486-1314 and as 2MASS J18513095-1310367) is a bipolar planetary nebula in the constellation of Scutum. [ 3 ] [ 4 ] It is centered about 32 000 ly away from Earth .
The Homunculus Nebula is a bipolar emission and reflection nebula surrounding the massive star system Eta Carinae, about 7,500 light-years (2,300 parsecs) from Earth. The nebula is embedded within the much larger Carina Nebula , a large star-forming H II region .
Sh 2-106, [2] also known as the Celestial Snow Angel, is an emission nebula and a star formation region in the constellation Cygnus.It is a H II region estimated to be around 2,000 light years (600 pc) from Earth, in an isolated area of the Milky Way.
Hen 2-437 is a bipolar planetary nebula in the constellation Vulpecula. The nebula is notable for its ice blue colorisation. It was first discovered by Rudolph Minkowski in 1946. Hen 2-437 formed when a low mass star similar to our sun swelled into its red giant phase ejecting its outer layers into space. [2]
