 NGC 4911 contains rich lanes of dust and gas near its center. These are silhouetted against glowing newborn star clusters and iridescent pink clouds of hydrogen, the existence of which indicates ongoing star formation. 4911 and other spirals near the center of the cluster are being transformed by the gravitational tug of their neighbors. In the case of 4911, wispy arcs of the galaxy's outer spiral arm are being pulled and distorted by forces from a companion galaxy, NGC 4911A, to the upper right. The resultant stripped material will eventually be dispersed throughout the core of the coma cluster, where it will fuel the intergalactic population of stars and star clusters.
