Quote: The 6dF Galaxy Survey has collected more than 120,000 redshifts over the southern sky over a 5 year period from 2001 to 2005. Its goal is to map our southern view of the local universe, and use the peculiar motions of one-tenth of the survey to measure galaxy mass. It covers more than eight times the sky area of the successful 2dF Galaxy Redshift Survey.
