Dark Energy Survey releases early data

Science Verification data from the Dark Energy Survey now publicly available. Covering only 3% of the full survey area, these data were used to create the largest dark matter mass map to date. The survey is being carried out with Dark Energy Camera (DECam) on the 4-m Blanco telescope at CTIO (pictured).

Powerful blasts from a giant black hole

Images of NGC 5195, the companion to M51, the Whirlpool Galaxy, show slender arcs of cool hydrogen-emitting gas (red in inset image) that border two giant arcs of hot X-ray emitting gas observed by NASA's Chandra X-ray Observatory (blue in inset). The arcs formed when hot gas expelled from the black hole swept up cooler gas from the center of the galaxy. The H-alpha image (red in inset) was taken with the Kitt Peak National Observatory 0.9-meter telescope.

Heavyweight Champion of the Distant Universe

Weighing in at 500 trillion times the mass of the Sun, the young galaxy cluster IDCS 1426, located 10 billion light years from Earth, is the most massive distant cluster known. Recently weighed using data from the Chandra X-ray Observatory and the Hubble Space Telescope, it was first identified with data from the NOAO Deep Wide-field Survey and data taken with the Spitzer Space Telescope.

Oodles of Faint Dwarf Galaxies in Fornax
Shed Light on a Cosmological Mystery

An astonishing number of faint low surface brightness dwarf galaxies recently discovered in the Fornax cluster of galaxies may help to solve the long-standing cosmological mystery of “The Missing Satellites”. The discovery, made by an international team of astronomers led by Roberto Muñoz and Thomas Puzia of Pontificia Universidad Católica de Chile, was carried out using the Dark Energy Camera (DECam) on the 4-m Blanco telescope at Cerro Tololo Inter-American Observatory (CTIO). CTIO is operated by the National Optical Astronomy Observatory (NOAO).

Coloring the Universe

A new book will give readers a behind-the-scenes look at how spectacular images of space are made by the world’s largest and most powerful telescopes. Featuring over three hundred large-format pictures, Coloring the Universe is an insider’s guide at what happens at the professional observatories (including NOAO) when we release color images of space. The book focuses on how the images are made, why they look the way they do, and what scientists learn from them.
