The galaxy UGC 6697 , which is about 1.5 million light years from the core of the Abell 1367 galaxy cluster , is shown here in a composite X-ray image (blue) and an optical image (red and green). The features in the picture show that the density of the hot gas pervading the cluster was just right to trigger an outbreak of star formation by compressing clouds of cold gas in the galaxy. As the galaxy heads toward the center of the cluster at a rate of several million miles per hour , the pressure created by this movement from the hot surrounding gas compresses cooler gas in the galaxy, pushing it away from the edge of the galaxy. The faint blue X-ray tail that extends in the top right of the image comes from gas that is stripped out of the galaxy through its interaction with the gas in the hot cluster. Over time, this stripping process removes all of the gas from the galaxy, so that no new outbreaks of star formation can occur in this way .
