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.

NOAO Staff on team receiving the 2015 Breakthrough Prize in Fundamental Physics

The prize, for the unexpected discovery that the expansion of the universe is accelerating, rather than slowing as had been long assumed, is a shared honor with Saul Perlmutter, Brian Schmidt, and Adam Riess leading a collaboration of 51 total prize recipients splitting $3 million. Significant work on this project was done at the CTIO Blanco 4-meter telescope by current NOAO staff members Chris Smith and Tom Matheson, and former NOAO employees Bob Schommer, Nick Suntzeff, Mark Phillips, and Alejandro Clochiatti along with various other current and former AURA employees.
