NASA Solicits Proposals for a World-class Precision Doppler Spectrometer at Kitt Peak National Observatory

Kitt Peak National Observatory is the future home of a state-of-the-art instrument that will be used to detect and characterize other worlds. The new instrument, an extreme precision radial velocity spectrometer, will measure the subtle motion of stars produced by their orbiting planets. The spectrometer, funded by NASA, will be deployed on an existing telescope at Kitt Peak, the 3.5-meter WIYN telescope.

DESI Corrector Lens, C1, measuring 1.15m in diameter

DESI Project Delivers Major Optical Elements

The Dark Energy Spectroscopic Instrument (DESI) project has delivered major optical elements to Arizona Optical Science and L3-Brashear for figuring and polishing. Above is an image of the largest corrector lens, C1 measuring 1.15m in diameter. The homogeneity of the fused silica glass came in at an astounding 1ppm (exceeding the 3ppm spec). DESI will be conducted on the Mayall 4-meter telescope at Kitt Peak National Observatory starting in 2018.

Smashing Results About Our Nearby Galactic Neighbors

An early result from the Survey of the Magellanic Stellar History (SMASH), carried out by an international team of astronomers using telescopes that include the Blanco 4-meter at Cerro Tololo Inter-American Observatory (CTIO) in Chile, suggests the the Magellanic Clouds are much bigger than astronomers calculated, and also have non-uniform structure at their outer edge, hinting at a rich and complex field of debris left over from their formation and interaction. Results were presented at the 225th meeting of the American Astronomical Society in Seattle, Washington.

The green circles in the image above show some of the DECam pointings of the SMASH survey, indicating the area where Magellanic Cloud stars have been found.
