Protecting Dark Skies for Astronomy and Life
Artificial light at night is a threat to astronomical research, personal safety, and the health of humans and wildlife. To address the challenge posed by the proliferating use of LEDs for billboards and street lighting, NOAO, in partnership with other concerned organizations, recently convened a workshop to showcase successful strategies for reducing light pollution. The workshop was held at the January meeting of the American Astronomical Society (AAS) where the AAS Council announced a three-part resolution on light pollution, including calling on all AAS members to protect dark skies in their communities.

NOAO announces with sorrow the death of Dr. Vera Rubin
Dr. Vera Rubin began observing at Kitt Peak National Observatory in 1963 at the 36-inch telescope. With her colleague Kent Ford, she continued using the Kitt Peak 2.1-m, accumulating over 60 galaxy rotation curves over the following years. Flat rotation curves were directly visible from the spectra: these data provided compelling observational evidence for a new kind of matter in the Universe, “dark matter”. Vera Rubin continued observing at Kitt Peak and Cerro Tololo throughout her long career, and will be greatly missed by the entire NOAO science staff, the mountain technical staff, and everyone who had the good fortune to meet her.

DECam Legacy Survey Announces Third Data Release
The DECam Legacy Survey (DECaLS) has released reduced images and source catalogs covering between 4000 and 8000 square degrees of sky in three wavelength bands. Dive into survey images and explore the Universe with the survey’s Imagine Sky Viewer. DECaLS, which is being carried out on the CTIO Blanco telescope, is one of three public surveys that will jointly image 14,000 square degrees of sky to provide targets for the upcoming Dark Energy Spectroscopic Instrument cosmology project at the Kitt Peak Mayall telescope.

Maximizing Science in the Era of LSST
A recent community-based study takes a science-driven look at the question “What supporting OIR capabilities will be needed to maximize the science enabled by the Large Synoptic Survey Telescope (LSST)?” The study report quantifies needed capabilities and highlights ways that existing, planned, and future resources can be positioned to accomplish community science goals.

New Insights into the ‘Golden Age’ of Galaxy Formation
Studies of a distant corner of the Universe, the Hubble Ultra Deep Field, made with the Atacama Large Millimeter Array (ALMA) have revealed distant galaxies rich in molecular gas. Their high gas content likely fueled the high rate of star formation during the “Golden Age” of galaxy formation 10 billion years ago. The discovery was made by international team of astronomers, including NOAO astronomer Mark Dickinson.
