 New images from Hubble show D100, a spiral galaxy, being stripped of its gas as it plunges towards the cluster's center. A long, thin stream of gas and dust stretches from the galaxy's core and on into space. The tail, a mixture of dust and hydrogen gas, extends nearly 200,000 light-years. But the structure is comparatively narrow, only 7,000 light-years wide. We saw this ram stripping earlier with Galaxy ESO 137-01. Eventually, the galaxy will lose all of its gas. Without the material to create new stars, star formation in the galaxy will cease. It is estimated that the gas stripping process in D100 began roughly 300 million years ago. Adding to this story is another galaxy in the image that foreshadows D100's fate. The object named D99 began as a spiral galaxy similar in mass to D100. It underwent the same violent gas loss process as D100 is now undergoing, and it can no longer form new stars.
