Spectroscopy is a technique that astronomers use to measure and analyze the hundreds of colors contained in the light emitted by stars, galaxies and other celestial objects.
The pursuit of dark matter and dark energy is one of the most exciting—and most challenging—areas of science. Now researchers think they’re beginning to close in.
The BOSS collaboration has looked so far back in time that they observed the period before dark energy began to dominate the largest scales of the universe.
