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.

NSF Funds Open Access to Las Cumbres Observatory
Beginning in 2017, open access time on the LCO global telescope network will be available to the US community through the NOAO TAC. The LCO network includes nine 1m and two 2m optical telescopes that are optimized for time-domain studies. A call for proposals will be issued by NOAO early next year. Read More...

Pluto Spray Paints its Moon Red
The red color near the north pole of Charon, Pluto’s largest moon, originates on Pluto. Once a mystery, it now appears that the red color of “Mordor Macula” arises as methane gas escapes from Pluto’s atmosphere and freezes onto the icy surface of Charon’s north pole. UV light from the Sun then transforms the methane into reddish organic materials. The New Horizons team that reported this result includes NOAO astronomer Tod Lauer.

Ultra-faint stellar systems discovered toward the Sagittarius stream
Astronomers have discovered ultra-faint stellar systems in the direction of the Sagittarius stream, the stream of stars that is being pulled out of the Sagittarius dwarf galaxy as it orbits our own Milky Way galaxy. Similar in size to globular clusters but much fainter, the new stellar systems straddle the fuzzy boundary between dwarf galaxies and stellar clusters. The discovery was made by a team of astronomers using data from the Dark Energy Survey being carried out at CTIO. Team members include NOAO astronomers Kathy Vivas, Tim Abbott, David James, Chris Smith, and Alistair Walker. Read More...
