阿贝尔36（Abell 36）是一个暗淡的行星状星云[6]，位于室女座，距离地球780光年[3][5][7]。美国天文学家乔治·阿贝尔于1955年发现阿贝尔36星云[8]。
阿贝尔36星云环绕着一颗垂死的类太阳恒星，该恒星正在脱落外层，形成阿贝尔36。
这颗恒星正向白矮星生命阶段演化[9]。根据估计，阿贝尔36星云形成于大约10,000年前[10]。

The gorgeous, gaseous shroud of a dying sunlike star, planetary nebula Abell 36 lies a mere 800 light-years away in the constellation of Virgo. At that distance it spans over 1.5 light-years in this sharp telescopic view. Shrugging off its outer layers, the nebula's central star is contracting and becoming hotter, evolving towards a final white dwarf phase. In fact, in Abell 36, the central star is estimated to have a surface temperature of over 73,000 K, compared to the Sun's present 6,000 K temperature. As a result, the intensely hot star is much brighter in ultraviolet light, compared to its visual appearance here. The invisible ultraviolet light ionizes hydrogen and oxygen atoms in the nebula and ultimately powers the beautiful visible light glow.

Abell 36 is a planetary nebula (PK 318+41.1) at RA 13h 41m 17s and DEC -19d 53m 10s in the constellation of Virgo. The field is 21' x 21' and north is to the upper left. The apparent size of the object is approximately 7.6' N-S and 4.8' E-W. It is estimated to be close at 780 light years distant with an age ranging from 4,700 to 8,000 years. The bright, central star in the image, FB138, is estimated to have an effective temperature of > 73,000 K. This image of the core was identified by Abell in 1966 from POSS plates. It is considered to have a bipolar structure.
