Galactic supercluster -
This image captures the galaxy cluster Abell 2029 and a central galaxy IC1101, located on the boundary between the constellations of Virgo and Serpens (Caput). You can find it about 4 degrees northwest of a major globular cluster M5 in Serpens (Caput). IC1101 locates just 4 arc minutes into the territory of Virgo from the boundary line of the two constellations.
Abell 2029 contains about 80 galaxies and floats at a distance of around 1 billion light-years. IC1101, visible at its center, has a real diameter of up to 4 million light-years, making it one of the largest galaxies known, nearly 40 times the size of the Milky Way Galaxy. Such massive elliptical galaxies are believed to have formed through the collisions of multiple galaxies.
