ASTRONOMERS STEP UP SEARCH FOR DARK ENERGY

摘要

The most ambitious project yet to map the three-dimensional structure of the universe in a quest to understand dark energy is underway by astronomers from the University of Arizona, Tucson, and 41 other institutions. "Making a three-dimensional map is essential to understanding why the universe is expanding at an ever-accelerating rate," explains Daniel Eisenstein, UA professor of astronomy and director of the Sloan Digital Sky Survey III, a collaboration of 350 scientists. The project is called the Baryon Oscillation Spectroscopic Survey (BOSS).
