Nebulae :: PFP 1



Resolutions Available: 941x942 : 1710x1712 : 2850x2853
         Object PFP 1
         Comment Discovered in 2004 by astronomers Mark J. Pierce, David J. Frew and Quentin A. Parker, PFP 1 (aka PN G222.1+03.9) is a remarkably annular planetary nebula located in Monoceros measuring 19 arc-minutes across making it one of the largest of its type. PFP 1 has an estimated radius of 10 light years and has near perfect symmetry, broken only at the north west edge which is coupled with significantly increased hydrogen atom intensity. This arc of intense nebulosity was previously detected in POSS I and II red plates and those of the SERC ER survey as an elongated wisp of nebulosity. The large diameter ring is near undetectable due to its extremely low surface brightness. PFP 1 is estimated as being 1,800 light years away. Reference
