"SDSS-III's newest release is Data Release 10 (DR10). DR10 contains the first spectra of the APO Galactic Evolution Experiment (APOGEE), as well as additional sky coverage and better galaxy parameter estimates from BOSS."

New results from digital sky surveys highlight more inconsistencies in our understanding of early galaxies, which, in contrast to today's galaxies, were compact and rapidly moving.

Halo and Galaxy Formation Histories from the Millennium Simulation Public release of a VO-oriented and SQL-queryable database for studying the evolution of galaxies in the ΛCDM cosmogony

This web page is designed to give everyone an idea of what our universe actually looks like. There are nine main maps on this web page, each one approximately ten times the scale of the previous one. The first map shows the nearest stars and then the other maps slowly expand out until we have reached the scale of the entire visible universe.

SETILive is taking the Search for Extraterrestrial Intelligence (SETI) directly to you by presenting radio frequency signals LIVE from the SETI Institute's Allen Telescope Array (ATA) while it's pointed at stars that, based on Kepler exoplanet discoveries, have the best chances of being home to an alien civilization. We'll also be putting you "in the loop" where if enough of you see a potential extraterrestrial (ET) signal in the same data, then within minutes, the ATA will be interrupted and sent back to take a second look. The data you see will be from frequencies where human-made Radio Frequency Interference (RFI) crowds them and we believe the human eye will have a better chance than SETI's computer algorithms to find ET signals there.

The Open Data project is part of the NASA Open Government Initiative, and is intended to improve access to NASA data. This data catalog is a continually-growing listing of publicly available NASA datasets.

Building on the legacy of the Sloan Digital Sky Survey (SDSS) and SDSS-II, the SDSS-III Collaboration is working to map the Milky Way, search for extrasolar planets, and solve the mystery of dark energy.

Chromoscope lets you explore our Galaxy (the Milky Way) and the distant Universe in a range of wavelengths from gamma-rays to the longest radio waves.

This dataset consists of a conversion of the NASA NSSDC Master Catalog and extracts of the Apollo By Numbers statistics.

The Bolshoi simulation is the most accurate cosmological simulation of the evolution of the large-scale structure of the universe yet made ("bolshoi" is the Russian word for "great" or "grand").  The first two of a series of research papers describing Bolshoi and its implications have been accepted for publication in the Astrophysical Journal. The first data release of Bolshoi outputs, including output from Bolshoi and also the BigBolshoi or MultiDark simulation of a volume 64 times bigger than Bolshoi, has just been made publicly available to the world's astronomers and astrophysicists.

The WorldWide Telescope (WWT) is a visualization environment that enables your computer to function as a virtual telescope-bringing together imagery from the world's best ground- and space-based telescopes for the exploration of the universe. WWT blends terabytes of images, information, and stories from multiple sources into a seamless, immersive, rich media experience. Explorers of all ages will feel empowered to explore and understand the cosmos using WWT's simple and powerful user interface.
