The background image is an all-sky image of galaxies in the near-infrared waveband from 2MASS. The image is in "Supergalactic" coordinates and shows over 1.6 million galaxies brighter than Ks=13.5 colour-coded so that blue are the brightest, green are moderately bright and red are the faintest. Also shown are 500 million stars which lie around the blue-band which represents the Milky Way. Detailed information and further images here (Credit: 2MASS - Tom Jarrett).

The four inset images are (from top to bottom):

A parallel tree-code simulation (constrained realization) of the distribution of galaxies in the Local Universe. See the home page of Volker Springel for a bibliography (e.g. Mathis et al. MNRAS, 333, 739, 2002).
A HIPASS image of 5000 galaxies from the deep catalogue (HICAT). Colours correspond to different velocity ranges. The south celestial pole is at the image centre (Meyer, Zwaan et al.)
A slice of the Universe as seen by the 2dF galaxy redshift survey.
The NASA Wilkinson Microwave Anisotropy Probe, recently responsible for a new high-angular resolution map of the microwave sky. Bibliography and further information.
