An Umbrella and a Dwarf


NGC 4651 is a spiral galaxy located in the constellation of Coma Berenices. It’s a member of the Virgo Cluster and is known as the Umbrella Galaxy because of the umbrella-shaped structure extending from its disk composed of stellar streams that are the remnants of a much smaller galaxy that’ been torn apart by NGC 4651’s tidal forces. Studies using radio telescopes show distortions on NGC 4651’s outer regions and a gas clump associated with a dwarf galaxy that may have born in the event that produced those stellar streams.
