帕洛马天文台施密特、欧洲南方天文台施密特和联合王国施密特、红色天文卫星和2微米全天巡天计划所进行的全天巡天已被证明是天文学上极为有用的工具，其价值可持续数十年。广域红外巡天探测器（WISE）于2009年12月14日发射升空，目前正在绘制整个天空的地图。WISE于2010年1月14日开始测量天空，并于7月17日完成了首次全面覆盖。该调查将继续覆盖天空的第二次，直到冷冻剂耗尽（预计在2010年11月）。WISE在黄道上的非混淆区域中，在波长为3.4、4.6、12和22 μm的波段中，实现了优于0.08、0.11、1和6 mJy的5σ点源灵敏度。由于覆盖更密集和黄道带背景更低，因此对黄道两极的敏感度提高。在3.4、4.6、12和22 μm处，角分辨率分别为6.″1、6.″4、6.″5和12.″0，对高信噪比源的天体测量精度优于0.″15。
The all sky surveys done by the Palomar Observatory Schmidt, the European Southern Observatory Schmidt, and the United Kingdom Schmidt, the InfraRed Astronomical Satellite, and the Two Micron All Sky Survey have proven to be extremely useful tools for astronomy with value that lasts for decades. The Wide-field Infrared Survey Explorer (WISE) is mapping the whole sky following its launch on 2009 December 14. WISE began surveying the sky on 2010 January 14 and completed its first full coverage of the sky on July 17. The survey will continue to cover the sky a second time until the cryogen is exhausted (anticipated in 2010 November). WISE is achieving 5σ point source sensitivities better than 0.08, 0.11, 1, and 6 mJy in unconfused regions on the ecliptic in bands centered at wavelengths of 3.4, 4.6, 12, and 22 μm. Sensitivity improves toward the ecliptic poles due to denser coverage and lower zodiacal background. The angular resolution is 6.″1, 6.″4, 6.″5, and 12.″0 at 3.4, 4.6, 12, and 22 μm, and the astrometric precision for high signal-to-noise sources is better than 0.″15.
