W48 Region

March 31, 2003
Atlas Image Mosaic, covering 10.0´ × 10.0´ on the sky, of the HII region W48. There is no optical counterpart to this radio emission region, due to its proximity to the Galactic plane, its distance of 3.4 kpc (11084 light years), and about 23 visual magnitudes of extinction, but it is obvious in the 2MASS near-infrared image. The center of W48 is still heavily obscured, with dark dust lanes running through it. W48 is at the edge of more extended molecular gas cloud. The dusty nebula appears to be the site of ongoing massive star formation. 2000 Dec 27-2001 Jan 2
