The bottom image shows The Sloan Foundation Measure distances to the thousands of galaxies in Data Release 9. Guide us, or someone else, in solving these mysteries." Said David Schlegel of Lawrence Berkeley National Laboratory, who led the SDSS-IIIĮffort to map these galaxies and quasars. "Dark matter and dark energy are two of the greatest mysteries of our time," How much of the Universe is made up of dark matter - matter that we can'tĭirectly see because it doesn't emit or absorb light - and dark energy, theĮven more mysterious force that drives the accelerating expansion of the Universe. With that history, they can get better estimates for With such a map, scientists can retrace the history of the Universe over the Gas - from as long ago as 12 billion years in the past. Galaxies over the past six billion years of cosmic time, as well asġ60,000 quasars - giant black holes actively feeding on stars and Which will eventually measure the positions of 1.5 million massive This release includes new data from the ongoing SDSS-IIIīaryon Oscillation Spectroscopic Survey (BOSS), Is to create a map of the Universe that will be used long after we areĭone, by future generations of astronomers, physicists and the generalĭata Release 9 is the latest in a series of data releases stretchingīack to 2001. "What really makes me proud of this survey is our commitment toĬreating a legacy for the future," said Michael Blanton, a professorĪt New York University who led the team that prepared DR9.
