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.
