Description
Universe's galaxies, all-sky 2MASS Extended Source Redshift Catalog (XSCz). This catalogue contains more than 1.5 million galaxies, while the Point Source Catalog includes nearly 500 million stars within the Milky Way. The galaxies are color coded for distances. The nearest sources are blue (redshifts less than 0.01), moderately distant sources (redshifts between 0.01 and 0.04) are green, and red represents the farthest sources that 2MASS resolves (between redshifts of 0.04 and 0.1) For a similar survey, see image C045/6541.
