Most Detailed Images of Uranus obtained with the Keck telescope show numerous cloud features at the north pole and scalloped waves at the equator. Click on the thumbnail for more information, images and references.

The Dark Side of the Rings of Uranus: The rings of Uranus are oriented edge-on to Earth for the first time since their 1977 discovery. This provides a rare opportunity to observe their dark (unlit) side, where dense rings darken to near invisibility, but faint rings become much brighter. We present the first ground-based infrared image of the unlit side of the rings. Click on the thumbnail for more information, images and references.

One Ring, Two Ring, Red Ring, Blue Ring: Uranus' two new rings show a striking similarity to Saturn's outer rings. Both planets show a red inner and blue outer ring, at approximately the same locations relative to their parent planet. Click on the thumbnail for more information, images and references.

URANUS: NEW RING R/2003 U 2 Visible light HST images by M. Showalter and J.J. Lissauer revealed the presence of two new rings outside the planet's main ring system: R/2003 U 1 and R/2003 U 2. We imaged the inner of the two rings with NIRC2 on 10-m W.M. Keck telescope at a wavelength of 2 micron. Click on the thumbnail for more information, images and references.

URANUS' RINGS IN 2004 Near infrared image of Uranus' ring system taken with AO on Keck II on 3-9 July 2004 at K'-band (2.2 micron) reveal all rings in Uranus' ring system, including 1986U2R, imaged only once by the Voyager spacecraft.

URANUS: CLOUDS IN 2004 AND K' FEATURE Keck Adaptive Optics images of Uranus obtained with the Keck telescope on 3,4,8 and 9 July 2004. First time a cloud on Uranus' southern hemisphere is seen at K'-band. Click on the thumbnail for more information, images and references.

URANUS' RINGS IN 2003 Near infrared image of Uranus' ring system taken with AO on Keck II on 3-6 October 2003 at J (1.2 micron), H (1.6 micron) and K'-band (2.2 micron) reveal all the narrow rings in Uranus' ring system.

URANUS: FIRST AO IMAGE (2000) Near infrared image of Uranus taken by Keck II that marks the first ground-based detection of the faint inner rings around that planet. The image is obtained at infrared wavelengths between 1.6 and 2.3 micro-meters. The planet itself is artificially darkened by a factor of about 20. Clearly visible are the methane haze layer on Uranus's south polar cap, and the tiny cloud features at high northern latitudes. Inside the bright epsilon ring three fainter rings can be discerned, which each consist of multiple ringlets. Click the thumbnail for reference and enlargement.
