A new pair of lenses for the Mayall
To be deployed as part of the Dark Energy Spectroscopic Instrument project, the lenses, which weigh a quarter ton, will help us see the effect of dark energy on the expansion history of the universe.

Gravitational waves detected 100 years after Einstein’s prediction
Ripples in the fabric of spacetime produced by two merging black holes were detected by the Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO; top inset). The announcement comes 100 years after Albert Einstein’s prediction of the existence of gravitational waves and signals the opening of the gravitational wave Universe. The wide-field imaging capability of DECam at CTIO (bottom inset) was used to search for the optical counterpart of the gravitational wave event.

After quick makeover, KPNO camera sees redder better
The Mosaic-3 camera, mounted on the 4-m Mayall, is on a two-year mission to image the sky in preparation for the Dark Energy Spectroscopic Instrument. Now equipped with cutting-edge, red-sensitive charge-coupled devices (CCDs, top inset image) and new mechanical components (including the focal plate; bottom inset image), Mosaic-3 is the product of a small collaboration of scientists and engineers at Berkeley Lab, Yale University, and NOAO.

Dark Energy Survey releases early data
Science Verification data from the Dark Energy Survey now publicly available. Covering only 3% of the full survey area, these data were used to create the largest dark matter mass map to date. The survey is being carried out with Dark Energy Camera (DECam) on the 4-m Blanco telescope at CTIO (pictured).

Powerful blasts from a giant black hole
Images of NGC 5195, the companion to M51, the Whirlpool Galaxy, show slender arcs of cool hydrogen-emitting gas (red in inset image) that border two giant arcs of hot X-ray emitting gas observed by NASA's Chandra X-ray Observatory (blue in inset). The arcs formed when hot gas expelled from the black hole swept up cooler gas from the center of the galaxy. The H-alpha image (red in inset) was taken with the Kitt Peak National Observatory 0.9-meter telescope.
