2MASX J00482185-2507365 occulting pair
The 2MASX J00482185-2507365 occulting pair is a pair of overlapping spiral galaxies found in the vicinity of NGC 253, the ''Sculptor Galaxy''. Both galaxies are more distant than NGC 253, with the background galaxy, 2MASX J00482185-2507365 (PGC 198187), lying at redshift z=0.06, and the foreground galaxy lying between NGC 253 and the background galaxy (0.0008 < z < 0.06).〔(arXiv:0810.2646v1 ) ; An extended dust disk in a spiral galaxy; An occulting galaxy pair in ANGST ; ; ''B. W. Holwerda, W. C. Keel, B. Williams, J. J. Dalcanton, R. S. de Jong'' ; ''15 Oct 2008'〕
This pair of galaxies illuminates the distribution of galactic dust beyond the visible arms of a spiral galaxy. The heretofore unexpected extent of dust beyond the starry limits of the arms shows new areas for extragalactic astronomical study. The dusty arms extend 6 times the radii of the starry arms of the galaxy, and are shown silhouetted in HST images against the central and core sections of the background galaxy.〔Astronomy; Galaxy's Dark Secret Exposed ; ''Daniel Pendick'' ; pp.20 Vol.37 Issue.1 January 2009 ;〕
