Galaxy Cleaned Out by Encounter with Hot Cluster Gas |  This three-color composite image of spiral galaxy NGC 4402 shows several key lines of evidence for the galaxy being stripped bare of its star-forming material by its violent ongoing encounter with the hot gas in the center of the Virgo galaxy cluster, as NGC 4402 falls into it. Released at the AAS meeting in Denver.
