Details of the galaxy's structure are visible because interstellar dust clouds that trace its disc are silhouetted from behind by light from the galaxy's bright, smooth central bulge. ESO 510-G13 lies in the southern constellation Hydra, some 150 million light-years from Earth. The new image of the galaxy ESO 510-G13 shows an unusual twisted disc structure, first seen in ground-based photographs taken at the European Southern Observatory in Chile. The dust and spiral arms of normal spiral galaxies, like our Milky Way, look flat when seen edge- on. During observations of the galaxy, the camera passed a milestone, taking its 100,000th image since shuttle astronauts installed it in Hubble in 1993. The camera was designed and built by NASA's Jet Propulsion Laboratory, Pasadena, Calif. The image, taken by Hubble's Wide Field and Planetary Camera 2 (WFPC2), is online at hive/releases/2001/23/image/a/. NASA's Hubble Space Telescope has imaged an unusual edge-on galaxy, revealing remarkable details of its warped dusty disc and showing how colliding galaxies trigger the birth of new stars.
