Washington (UPI) Aug 11, 2010 A new Hubble telescope image of a face-on spiral galaxy shows lanes of dust and gas at its center, evidence of ongoing star formation, U.S. astronomers say. A long-exposure image shows a majestic galaxy titled NGC 4911 located deep within the Coma Cluster of galaxies, which lies 320 million light-years away in the northern constellation of Coma Berenices, a NASA release said Tuesday. The image required 28 hours of exposure time using Hubble's brand new Wide Field Planetary Camera 2 and the Advanced Camera for Surveys, Britain's Daily Telegraph said. NASA scientists say the Coma Cluster is one of the densest collections of galaxies in the nearby universe where galaxies often interact violently with each other. The long wispy formations, seen along the "arms" of the main galaxy, are a result of NGC 4911 and a companion galaxy passing "perilously close to each other," NASA says. "The high resolution of Hubble's cameras, paired with considerably long exposures, made it possible to observe these faint details," a NASA spokesman said.

Hubble Snaps Sharp Image Of Cosmic ConcoctionParis, France (ESA) Jul 15, 2010 Strangely shaped dust clouds, resembling spilled liquids, are silhouetted against a colourful background of glowing gas in this newly released Hubble image. The star-forming region NGC 2467 is a vast cloud of gas - mostly hydrogen - that serves as an incubator for new stars. Some of these youthful stars have emerged from the dense clouds where they were born and now shine brightly, hot and ... read more |
