01/22/10
Description Two spectacular tails of X-ray emission have been seen trailing behind a galaxy using the Chandra X-ray Observatory. A composite image of the galaxy cluster Abell 3627 shows X-rays from Chandra in blue, optical emission in yellow and emission from hydrogen light -- known to astronomers as 'H-alpha' -- in red. The optical and H-alpha data were obtained with the Southern Astrophysical Research (SOAR) Telescope in Chile. At the front of the tail is the galaxy ESO 137-001. The brighter of the two tails has been seen before and extends for about 260,000 light years. The detection of the second, fainter tail, however, was a surprise to the scientists. The X-ray tails were created when cool gas from ESO 137-001 (with a temperature of about ten degrees above absolute zero) was stripped by hot gas (about 100 million degrees) as it travels towards the center of the galaxy cluster Abell 3627. What astronomers observe with Chandra is essentially the evaporation of the cold gas, which glows at a temperature of about 10 million degrees. Evidence of gas with temperatures between 100 and 1,000 degrees Kelvin in the tail was also found with the Spitzer Space Telescope. Galaxy clusters are collections of hundreds or even thousands of galaxies held together by gravity that are enveloped in hot gas. The two-pronged tail in this system may have formed because gas has been stripped from the two major spiral arms in ESO 137-001. The stripping of gas is thought to have a significant effect on galaxy evolution, removing cold gas from the galaxy, shutting down the formation of new stars in the galaxy, and changing the appearance of inner spiral arms and bulges because of the effects of star formation.

Huygens Landing Site
Description Huygens landing site
Full Description This image provides a comparison between the Huygens landing site on Titan as viewed by the Cassini Imaging Science Subsystem (ISS) and the NACO/SDI instrument mounted on the 8-meter Yepun telescope of the VLT (Very Large Telescope) station, in Chile. From the two images it is possible to see a high consistency between the two measurements. The Cassini image - taken in the near-infrared (938 nanometers)- shows the Huygens landing site map wrapped around Titan, rotated to the same position as the January 2005 NACO/SDI observations. The colored lines outline the regions that were imaged by Cassini at different resolutions. The lower-resolution imaging sequences are outlined in blue. Other areas have been specifically targeted to build moderate and high-resolution mosaics of surface features. These include the site where the Huygens probe has touched down on Jan. 14, 2005 (marked with the yellow X), and located at a latitude of 10.3° south and a longitude of 192.32° west (or 167.7° east). The landing site is located on the boundary between the bright region called Adiri and the dark one called Shangri-la. The red color on the NACO/SDI image corresponds to an atmospheric filter at 1.625 micron, while the blue color corresponds to a filter for the surface at 1.600 and 1.575 micron. *Credits:* NASA/JPL/Cassini-ISS/Space Science Institute and ESO/NACO-SDI/VLT

Title The Violent Lives of Galaxies: Caught in the Cosmic Dark Matter Web
General Information What is an American Astronomical Society Meeting release? A major news announcement issued at an American Astronomical Society meeting, the premier astronomy conference. Astronomers are using NASA's Hubble Space Telescope to dissect one of the largest structures in the universe as part of a quest to understand the violent lives of galaxies. Hubble is providing indirect evidence of unseen dark matter tugging on galaxies in the crowded, rough-and-tumble environment of a massive supercluster of hundreds of galaxies. Dark matter is an invisible form of matter that accounts for most of the universe's mass. Hubble's Advanced Camera for Surveys has mapped the invisible dark matter scaffolding of the supercluster Abell 901/902, as well as the detailed structure of individual galaxies embedded in it. The image, taken by NASA's Hubble Space Telescope, shows the supercluster. The magenta clumps throughout the image reveal the distribution of dark matter in the cluster. The galaxies lie within the clumps of dark matter. The image was assembled by combining a visible-light image of the supercluster taken with the MPG/ESO 2.2-meter telescope in La Silla, Chile, with a dark matter map derived from Hubble observations.

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.
