... 2012 March 13 . The M81 Galaxy Group Through the Integrated Flux Nebula . ... Explanation: Large galaxies and faint nebulae highlight this deep image of the M81 Group of galaxies. First and foremost in the wide-angle 12-hour exposure is the grand design spiral galaxy M81 , the largest galaxy visible in the image. ... This whole galaxy menagerie is seen through the faint glow of an Integrated Flux Nebula , a little studied complex of diffuse gas and dust clouds in our Milky Way Galaxy . ...

... Credit Copyright: Nicolюs Villegas Explanation: Large galaxies and faint nebulae highlight this deep image of the M81 Group of galaxies. ... M81 is gravitationally interacting with M82 just below it, a big galaxy with an unusual halo of filamentary red-glowing gas. Around the image many other galaxies from the M81 Group of galaxies can be seen, as well as a lucky satellite glint streaking across the image left. ... Galaxy Wars: M81 versus M82 .

... A revised machine-readable source list for the Rees 38-MHz survey. ... 233R ============================================================================ We present a revised machine-readable source list for the Rees 38-MHz (or '8C') survey with improved positions and no redundancy. The Rees 38-MHz survey covers an area of about 1 sr north of declination +60 degrees. The angular resolution is 4.5 x 4.5cosec(dec) arcmin**2 and the limiting flux density over much of the survey area is about 1 Jy. ...
