Hoag's Object also known as PGC 54559 and PRC D-51, is a non-typical galaxy type called a ring galaxy due to it's ring-like appearance. Hoag's Object is located inside The Serpens Caput(Serpent Head) which is a part of The Serpens Constellation and is located 612.8 ± 9.4 Million Light Years from Earth.
Profile of Hoag's Object
Hoag's Object was discovered in 1950 by American Astronomer Arthur Allen Hoag who originally classified it as a Planetary Nebula or a Peculiar Galaxy. In the first announcement of the new discovery, Hoag proposed the hypothesis that the visible ring was because of gravitational lensing. This proposition was discarded later on due to the nucleus and the ring have the same exact redshift, and because more advanced telescopes revealed the weird structure of the ring. Hoag's Object has eight Billion Stars within the bounds of its existence. Hoag's Object mave have been a product of an extreme bar instability that occurred a few billion years ago within a barred spiral galaxy. In The Center point of the ring that big shiny object is a collection of old stars that combined to form the middle of Hoag's Object. The Hoag's Object is indeed unique and is definitely worth exploring more of in the future.
