... 2010 . ... The following images are mosaics obtained on 03 August 2010 at the National Solar Observatory/Dunn Solar Telescope with the Interferometric Bidimensional Spectrometer (IBIS). ... The final images are approximately 238 x 242 arcseconds, or 4 x 4 arcminutes, with a pixel scale of 0.0976 arcseconds per pixel. ... The images show a broad range of typical chromospheric structures, including sunspots, superpenumbra, plage, filaments, and quiet internetwork. ...

Most of these images were obtained by Mike Bessell, Michelle Buxton, Hwankyung Sung, Ralph Sutherland and Bob Watson at SSO using a 2Kx2K Site CCD behind a Nikon or Hasselblad lens or directly on the 1m telescope. A few images are from the Hubble Space Telescope. Some of the M42 images were obtained with the KPNO 1m and ESO NTT telescope. One image is a mosaic of IRAS images. ...

... Europa's ocean sits under a thick ice shell. If this ocean covers the moon's solid core, does the shell rotate at a different speed? ... To the best of our knowledge, Europa has an ice shell of a few to as many as 12 miles (20 kilometers) in thickness, underneath which lies a global 60-mile-deep (100km) liquid water ocean. ...

... The author of the cover picture is Vasilisa Verkhodanova. The picture symbolizes our perception of the world. The modified emblem of the SAO unifying the 6-m optical telescope and the raditelescope RATAN-600 of SAO RAS is placed in the center of the radio galaxy isophotes. From the one hand, we can investigate the properties of radio galaxies with these (and other) telescopes, and try to study physical processes providing their activity. ...

... The Great Nebula in Carina . ... Eta Carinae , the most energetic star in the nebula, was one of the brightest stars in the sky in the 1830s, but then faded dramatically. Eta Carinae is the brightest star near the image center, just left of the Keyhole Nebula . While Eta Carinae itself maybe on the verge of a supernova explosion, X-ray images indicate that much of the Great Carina Nebula has been a veritable supernova factory .

... Active Disk Building in a Local HI-massive LIRG . by Michelle Cluver (UCT) . ... However, the mid-infrared uncovers a star-forming disk housing an intense starburst with a star formation rate of approximately 21 Msun/yr (Cluver et al. 2008 , 2010 ).This luminous infrared galaxy (LIRG) appears to be undergoing asymmetric inside-out disk building, with a star formation efficiency comparable to local disk galaxies and quite different to merger-driven starbursts. ... today * ATNF | ...
