An infrared composite image of the two hemispheres of Uranus obtained with Keck Telescope adaptive optics. The component colors of blue, green, and red were obtained from images made at near infrared wavelengths of 1.26, 1.62, and 2.1 microns respectively. The images were obtained on July 11 and 12, 2004. The North pole is at 4 o'clock.
Funding for the telescopes and the Keck II adaptive optics system is provided by the W.M. Keck Foundation. Optimization for the Keck adaptive optics system is provided by the National Science Foundation and the Technology Center for Adaptive Optics, managed by UCSC under cooperative agreement No. AST 9876783 (de Pater). Additional funding was provided by NASA grants NAG5-11961, NAG5-10451 (Hammel) and NAG5 12206 (Sromovsky).
