Summary
| Description |
English:
Panoramic view of the entire near-infrared sky reveals the distribution of galaxies beyond the
Milky Way
. The image is derived from the
2MASS Extended Source Catalog (XSC)
—more than 1.5 million galaxies, and the Point Source Catalog (PSC)--nearly 0.5 billion Milky Way stars. The galaxies are color coded by
redshift
(numbers in parentheses) obtained from the
UGC
,
CfA
, Tully NBGC, LCRS,
2dF
, 6dFGS, and
SDSS
surveys (and from various observations compiled by the
NASA Extragalactic Database
), or photo-metrically deduced from the
K band
(2.2 μm). Blue/purple are the nearest sources (z < 0.01); green are at moderate distances (0.01 < z < 0.04) and red are the most distant sources that 2MASS resolves (0.04 < z < 0.1). The map is projected with an equal area Aitoff in the Galactic system (Milky Way at center).
