DECam Legacy Survey has its first data release
The public DECam Legacy Survey (DECaLS) is delivering a new dataset that will allow astronomers to probe the structure of the Milky Way, the nature of dark energy, and many other topics in astrophysics. The survey leads David Schlegel (Lawrence Berkeley National Laboratory) and Arjun Dey (NOAO) recently announced the first data release from the survey. The data and catalogs can be accessed at legacysurvey.org. Dive into survey images and explore the Universe using the survey’s Sky Viewer. Future releases are anticipated at 6 month intervals. The survey capitalizes on the wide-field imaging capability of DECam at CTIO.

Milky Way over CTIO
This stunning image of the Milky Way arching over CTIO was taken from the eastern edge of the observatory, looking West (and South and North). The panorama shows the central and brightest part of the Milky Way. The bright objects on the left are the two Magellanic Clouds; the Andromeda Galaxy is visible on the right, just above the horizon. The green and red stripes in the sky are from airglow; the orange domes are from light pollution.
The panorama is a composite of 9 images, taken on the night of July 31, 2014, with a Canon 6d and a Samyang 24mm lens.

NOAO Astronomer Helmut Abt turns 90
The recipient in 1952 of the first doctoral degree in astrophysics awarded by Caltech for his work on the nature of W Virginis stars, Abt has studied many topics involving stellar spectroscopy. His work established the basic properties of B-G main sequence stars and guided subsequent developments in theories of binary star formation and the dynamics of stellar atmospheres. In the 1950’s Abt helped to select the site for a national astronomical observatory by conducting an aerial site survey and exploring potential sites by Jeep, pack horse, and on foot. From 1971-1999, Abt served as Managing Editor for the Astrophysical Journal. From 1980 onward, his interest in publication practices in astronomy led to a series of papers on topics such as the relative value of smaller aperture telescopes, the productivity of astronomers as a function of age, and the half-life of astronomical publications.

The North America Nebula
NGC 7000 is a giant nebula in the constellation of Cygnus. Also known as the North America Nebula, this image shows only the southern tip, or the “Mexico”, part of the nebula. Emission nebula, like this one, are energized by the light from stars embedded within. The image was generated by combining data from observations in Hydrogen alpha (red), Oxygen [OIII] (green) and Sulfur [SII] (blue) filters. In this image, North is up, East is to the left.

All-women observing teams on Tololo (CTIO)
This photo was taken in the 0.9-m control room during the last night of the REU/PIA student observing run on Feb. 13, when just by chance all of the observers on the mountain were women. The group included DES observers, the DECam community observer, and the REU and PIA students. From left to right, the people in the photo are:
DECam community observer: Claudia Belardi, DES observer: Marcelle Soares-Santos, DES observer: Chihway Chang, CTIO postdoc: Catherine Kaleida, 0.9-m observer: Pia Amigo, 0.9-m observer: Sanzia Alves, CTIO PIA student: Pamela Soto, CTIO REU student: Brittany Howard
