NGC 4911 is a disturbed, warpedspiral galaxy with a bright prominent centralstarburst ring and located deep within theComa Cluster of galaxies, which lies some 300 million light years away in the northern constellation Coma Berenices.[5] NGC 4911 is believed to be interacting with its warped, barredlenticular companion (or any of its many other nearby companions), producing the enhanced star formation and shell-like appearance seen in optical images. The galaxy contains rich lanes of dust and gas near its centre. The existence of clouds ofhydrogen within the galaxy indicates ongoing star formation.[5] It is rare for a spiral galaxy to be situated at the heart of a cluster.
