This image the lunar crater Cabeus was taken on October 9, 2009 with the Palomar Observatory's 200-inch (5.1-meter) Hale Telescope and its adaptive optics system. Cabeus crater is located in the center, behind the large bright mountain. Cabeus was the target of the NASA LCROSS mission. The crater was chosen because it was thought to contain a substantial amount of water ice. It was hoped by the LCROSS mission team that the impact would send an ejecta plume above the lunar surface, which could be observed from ground-based telescopes. No plume was observed from any telescope, but water ice was detected from an orbiting NASA spacecraft.

Palomar's Adaptive Optics system removes the blurring effects of Earth's atmosphere to produce very high resolution images. This image is one of the highest resolution photos taken of the Moon from a ground-based telescope. The field of view is 71 km (40 arcseconds, with ~200m resolution), recorded at 2.1 microns wavelength. Images were produced by Antonin Bouchez of Caltech.

A bottom-up view of the 200-inch Hale Telescope at Palomar Observatory. The view shows the underside of the 200-inch mirror's cell with red cooling fans encircled by mechanical supports which help the mirror to retain its proper shape regardless of where the telescope is pointed. At the very center of the image is a bright spot, a reflection off of the telescope's secondary mirror some 50 feet above the primary mirror. Light from the camera flash passed up through the hole in the 200-inch mirror up to the secondary mirror and reflected back down to the camera. The photo was taken during an instrument change, catching the underside of the telescope in a rare moment with no camera attached to its lower (Cassegrain) focus.

Condor feeding!

This image is part of a ~1.6MB video provided by wildlife biologist Jim Petterson of the NPS Pinnacles National Monument, which, in cooperation with the Institute for Wildlife Studies, has deployed PTZ cameras connected through a wireless network. The development of this network was aided by a technology transfer workshop and allows biologists to monitor feeding activities of California condors on a continuous basis. A second ~5,9MB video provides more details and also shows bird interactions.
