NGC 2346 – A Cosmic Butterfly’s Delicate Wings
NOAO scientists, using the Gemini Observatory 8-meter telescope in Chile, have obtained the highest resolution image ever obtained for the planetary nebula NGC 2346. The new observations of this bipolar planetary nebula resolve details comparable in size to our own solar system. The team detected previously unresolved knots and filaments of molecular hydrogen gas - details that no other telescope on the ground or in space, not even the Hubble Space Telescope, has been able to resolve.

Above and Underneath
The 6th International Earth and Sky Photo Contest, co-hosted by NOAO and the founding institution “The World at Night”, highlights the natural beauty of the night sky and its growing battle with light pollution. The 10 winners of the 2015 contest, selected from among a 1000 entries taken in 54 countries, are shown in the contest video. The panel of judges included NOAO astronomer Connie Walker. This entry, “Above and Underneath” by Evgeny Trisko, was photographed in Pyatigorsk, in the Stavropol region of Russia. It is the fifth place winner from the “Against the Lights” category, which emphasizes the growing issue of light pollution and how it affects our view of the night sky. The panoramic view shows clouds illuminated by towns and villages hidden beneath the inversion layer.

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.
