MCG +01-02-015 is a spiral galaxy in the constellation Pisces. It is an example of a void galaxy,[4] and believed to be one of the most isolated galaxies known, with no other galaxies for around 100 million light-years in all directions.[5] It is located in the 0049+05 void[6] which is next to the Pisces-Cetus void.[6][7]
Observational history
MCG +01-02-015 was previously classified as an elliptical galaxy of class E2 although higher-resolution imaging has revealed it to be a barred spiral galaxy.[3]
Formation
It is theorized by many astrophysicists that void galaxies are the result of large galactic filaments being pulled on by the gravity of a neighboring super cluster out of the less densely populated areas. Galaxies such as MCG +01-02-015 are left behind by events such as these.[8]
