*Description*: This image of the elliptical galaxy NGC 1132 combines an image from NASA's /Chandra X-Ray Observatory/ obtained in 2004 with images from the /Hubble Space Telescope/ made in 2005 and 2006 in green and near-infrared light. The blue/purple in the image is the X-ray glow from hot, diffuse gas. The giant foreground galaxy, numerous dwarf galaxies in its neighborhood, and many much more distant galaxies in the background are seen in visible light. Technical facts about this news release: About the Object Object Name: NGC 1132 Object Description: Elliptical Galaxy Position (J2000): R.A. 02h 52m 51.72s Dec. -01° 16' 10."9 Constellation: Eridanus Distance: 318 million light-years or 97 megaparsecs About the Data Data Description: The image created from HST data from proposal 10558: M. West (European Organization for Astronomical Research in the Southern Hemisphere (ESO)), M. Gregg (University of California, Davis), P. Cote (Dominion Astrophysical Observatory), S. van den Bergh (Dominion Astrophysical Observatory), and M. Drinkwater (University of Queensland). Instrument: ACS/WFC Exposure Date(s): September 25, 2005; August 22, 2006 Exposure Time: 4.8 hours Filters: F475W (SDSS g), F850LP (SDSS z) About the Image Image Credit: NASA, ESA and the Hubble Heritage (STScI/AURA)-ESA/Hubble Collaboration Acknowledgment: M. West (ESO, Chile) Release Date: February 5, 2008 Color: The image is a composite of separate exposures made by the ACS instrument on the Hubble Space Telescope. Two filters were used to sample broad wavelength ranges. The color results from assigning different hues (colors) to each monochromatic image. A third, intermediate image was created by combining the two existing images and assigned to the intermediate primary color. In this case, the assigned colors are: F475W (g) blue F475W (g) + F850LP (z) green F850LP (z) red Orientation: Elliptical Galaxy NGC 1132 - Hubble [ http://imgsrc.hubblesite.org/hu/db/2008/07/images/a/formats/compass_large_web.jpg ] What is Hubble Heritage? A monthly showcase of new and archival Hubble images. Go to the Heritage site. The elliptical galaxy NGC 1132 reveals the final result of what may have been a group of galaxies that merged together in the recent past. Another possibility is that the galaxy formed in isolation as a "lone wolf" in a universe ablaze with galaxy groups and clusters. This image of NGC 1132 was taken with Hubble's Advanced Camera for Surveys. Data obtained in 2005 and 2006 through green and near-infrared filters were used in the composite. NGC 1132 is located approximately 318 million light-years away in the constellation Eridanus, the River. *News Release Number:*: STScI-2008-07c
