Dark Energy Spectrometer for Kitt Peak Receives Funding Green Light
The Dark Energy Spectroscopic Instrument (DESI), destined for the 4-m Mayall telescope at Kitt Peak, will chart out the role of dark energy in the expansion history of the universe. The US Department of Energy has announced its approval of Critical Decision 2 for the DESI project, authorizing its scientific scope, schedule, and funding profile. To carry out its mission, DESI will measure the redshifts of more than 30 million galaxies and quasars and create a map of the universe out to a distance of 10 billion light years.

On the Cover
An image from the Dark Energy Camera Legacy Survey (DECaLS), a public survey mapping 6700 square degrees, approximately one-sixth of the sky, using the Blanco 4-m telescope at the Cerro Tololo Inter-American Observatory. The image shows the interacting galaxy system UGC 12589 at a distance of 470 million light-years. The distorted morphologies and diffuse light result from the gravitational interaction between the galaxies.

Dark Energy Survey finds more celestial neighbors
Eight new dwarf galaxy “neighbors” of the Milky Way discovered in recent data from the Dark Energy Survey (DES). More than 20 such companions to our galaxy have been discovered this year, of which 17 were found in DES data. Dwarf satellite galaxies may provide valuable clues to the nature of dark matter and how galaxies like the Milky Way formed. The Dark Energy Survey is being carried out on the 4-m Blanco telescope at CTIO.

Astronomers find ‘teeny supermassive black hole’
Discovered in dwarf galaxy RGG118, the petite black hole, only 50,000 times the mass of the sun, is the smallest supermassive black hole to date. NOAO Hubble Fellow Amy Reines is a coauthor on the study.

Chilean Astronomical Site Becomes World’s First International Dark Sky Sanctuary
On Sunday, 9 August, 2015, at the International Astronomical Union meeting in Honolulu, Hawai’i, the International Dark-Sky Association announced that the site of the Associated Universities for Research in Astronomy (AURA) Observatory in the Elqui Valley of northern Chile will be recognized and designated as the first International Dark Sky Sanctuary in the world. The site will be known as the “Gabriela Mistral Dark Sky Sanctuary” after the famed Chilean poet.
