After 20 years and four previous phases, the Sloan Digital Sky Survey’s Phase V(SDSS V) is ready to give Yale astronomers a new look at the wonders of the cosmos.
The survey’s mission is ambitious: It aims to create a detailed, three-dimensional map of the universe, using a 2.5-meter, wide-angle optical telescope located at the Apache Point Observatory in New Mexico.
Previous SDSS surveys have mapped one-third of the sky. SDSS data have been used in more than 7,700 peer-reviewed, scientific papers, offering insights into the chemical makeup of the Milky Way and the structure of distant galaxies. It has also helped produce multi-color imaging for hundreds of millions of stars, and gleaned information about 100,000 asteroids and other objects
