what was it about?
An attempt to map the large-scale structure of the universe
CfA Redshift Survey
The Center for Astrophysics (CfA) Redshift Survey was the first attempt to map the large-scale structure of the universe. 
how does the redshift show galaxies are moving away from us If a source of the light is moving away from an observer, then redshift occurs; if the source moves towards the observer, then blueshift occurs. what is meant by this red term? In physics, redshift is a phenomenon where electromagnetic radiation (such as light) from an object undergoes an increase in wavelength. the kind of radiation you mentioned here; what is it actually? In physics, electromagnetic radiation refers to the waves of the electromagnetic field, propagating through space, carrying electromagnetic radiant energy. which equation is related to it? Maxwell's equations who is this person? James Clerk Maxwell was a Scottish scientist in the field of mathematical physics what is stated in this equation? According to Maxwell's equations, a spatially varying electric field is always associated with a magnetic field that changes over time. regarding the former shift we talked about; is there any survey done on it? Yes, the CfA Redshift Survey, the DEEP2 Redshift Survey, the Sloan Digital Sky Survey what is this shift's measurement? To determine the redshift, one searches for features in the spectrum such as absorption lines, emission lines, or other variations in light intensity when was the first mentioned survey done? 1977

CfA Redshift Survey [SEP] Introduction
The Center for Astrophysics (CfA) Redshift Survey was the first attempt to map the large-scale structure of the universe. The first survey began in 1977 with the objective of calculating the velocities of the brighter galaxies in the nearby universe by measuring their redshifts at the Smithsonian Astrophysical Observatory in Cambridge, Massachusetts. The redshift is the relative increase in the wavelength emitted by a light source, in this case a galaxy, moving away from an observer from which its speed and then, using Hubble's Law, its distance can be calculated. A 3-dimensional map of that part of the Universe could thus be produced.
