The Hobby-Eberly Telescope Dark Energy Experiment

HETDEX is a blind, spectroscopic survey to measure the evolution of Dark Energy via the large scale structure of the Lyα emitting galaxies of the 1.9 < z < 3.5 universe.   Since the survey is blind, it not only records the redshifts of over a million high-redshift galaxies, but it also obtains spectra for everything falling into its array of fibers, including low-redshift galaxies, nebulae, AGN and stars in the Milky Way.   It therefore enables an extremely wide variety of science. 

A full description of HETDEX can be found here.

For sample HETDEX data, see my HETDEX page.
