... Toward this goal, the Baryon Oscillation Spectroscopic Survey (BOSS) of the Sloan Digital Sky Survey -III (SDSS-III) has measured slight recurring density enhancements in galaxy densities up to six billion light years away ( redshift 0.7), when the universe was about half its current age. ... BOSS's measurements of this size scale indicate a strong universe component of dark energy , and so bolsters previous indications of this unusual composition. ... NASA Official: Jay Norris. ...

The Extragalactic ALFA Zone of Avoidance team is mapping the distribution of low-Galactic-latitude galaxies and large scale structures through detection of galaxies' 21-cm emission with ALFA. This Zone of Avoidance (ZOA) survey finds new HI galaxies which lie hidden behind the Milky Way, and also provides redshifts and other HI parameters for partially-obscured galaxies known at other wavelengths. ... Discovery and Follow-up of a Nearby Galaxy from the Arecibo Zone of Avoidance Survey. ...

... To shed new light on these mysteries, we combine the gravitational lensing power of 25 massive galaxy clusters with HST's enhanced panchromatic imaging capabilities (WFC3 and the restored ACS) to test structure formation models with unprecedented precision.
