What is the constellation where XXX is located?
NGC 4651
This member of the Virgo Cluster, located on its outskirts, is known as the Umbrella Galaxy due to the umbrella-shaped structure that extends from its disk to the east and that it is composed of stellar streams, being the remmants of a much smaller galaxy that has been torn apart by NGC 4651's tidal forces, something that explains why NGC 4651 has been included on Halton Arp's Atlas of Peculiar Galaxies as Arp 189 -galaxy with filaments-.
