The project, the Apache Point Observatory Galactic Evolution Experiment, or APOGEE,  is one of four experiments of the new Sloan Digital Sky Survey III, using the astronomical facilities at Apache Point Observatory in New Mexico. APOGEE was selected as a Sloan-III project through a competitive proposal led by U.Va. astronomers.

Though red giants are extremely bright, those in distant parts of the Milky Way - like the centre of our galaxy 25,000 light-years away - are largely obscured by massive clouds of interstellar dust scattered across the vastness of space. Because of these dust clouds, only a relatively small fraction of stars in the Milky Way can be observed in visible light.
Much more of our galaxy comes into view when astronomers use instruments that allow observations in the infrared. Infrared cameras and spectrographs observe light at wavelengths longer than visible light, allowing astronomers to peer through interstellar dust to detect the chemical makeup of stars and to calculate their motions and distances.

Astronomy is a science of origins.

"It's the ultimate exercise in archaeology" - Steven Majewski, a University of Virginia professor of astronomy and lead scientist on a new project to survey more than 100,000 Milky Way red giant stars - bright, bloated stars in a late stage of their evolution.

The project, the Apache Point Observatory Galactic Evolution Experiment, or APOGEE, is one of four experiments of the new Sloan Digital Sky Survey III, using the astronomical facilities at Apache Point Observatory in New Mexico. APOGEE was selected as a Sloan-III project through a competitive proposal led by U.Va. astronomers.

"The spectra of red giant stars contain the chemical and dynamical fingerprints needed to understand the assembly of our Milky Way galaxy. Our home galaxy, the Milky Way, is a typical spiral galaxy and an important laboratory for gaining a detailed understanding of galaxies in general. APOGEE will be the first truly comprehensive study of the chemistry of Milky Way stars. With APOGEE, we will gain enormous insight to the processes that make stars and that drive the formation and evolution of galaxies" - Steven Majewski.

In its latest step to develop an astronomy program, the University of Utah is joining a major international effort to map the heavens as a way to search for giant planets in other solar systems, study expansion of the universe and probe the mysterious dark matter and dark energy that make up most of the universe.
With a $450,000 grant from the Willard L. Eccles Charitable Foundation and a matching amount from the university, the Department of Physics is providing $900,000 to join the third phase of the Sloan Digital Sky Survey (SDSS-III), an effort by about 20 research institutions around the world. SDSS-III started July 15 and extends into 2014.

A University of Florida-led sky survey that may double the number of known planets outside the solar system is part of a major new survey program announced today at the American Astronomical Societys annual meeting in Austin, Texas.
The Sloan Digital Sky Survey III, slated to begin mid-year and end in mid-2014, consists of four independent surveys operated by the surveys consortium. One will probe the distant universe and seek to learn more about mysterious dark energy, while two of the surveys will map the Milky Way and examine origins of stars. The UF-led survey will seek to find giant planets orbiting nearby stars and uncover more about the conditions in which they form.
