The latest buzz from space is the stunning photo gallery trickling in from NASA's Curiosity rover, which landed safely late Sunday night. While the rover is a big step for space exploration, it's only the tip of the iceberg -- an almost inconceivably large iceberg:
Vast as this slice of the universe seems, its most distant reach is to redshift 0.1, corresponding to roughly 1.3 billion light years from Earth. SDSS Data Release 9 from the Baryon Oscillation Spectroscopic Survey (BOSS), led by Berkeley Lab scientists, includes spectroscopic data for well over half a million galaxies at redshifts up to 0.8 -- roughly 7 billion light years distant -- and over a hundred thousand quasars to redshift 3.0 and beyond.
