Pa 165
The 165th possible planetary nebula discovered by my good friend Dana Patchick back in 2016.
It is 188 arcsec in diameter and is located in Pegasus.
This deep image reveals the detailed structures within Pa 165.
The bright blue central star is a strong source of ultra-violet radiation as detected by GALEX (the Galaxy Evolution Explorer Space Telescope), indicating that this is likely to be the white dwarf of a planetary nebula.
