WebThe students will use a coloring page to complete a model of the CfA Redshift Survey. Using the supplied directions, students first color the key, then color-code the following features: Sun Galaxies 0-249 million light years Galaxies 250-499 million light years Galaxies 500-749 million light years Stick Man Great Wall Voids In astronomy, a redshift survey is a survey of a section of the sky to measure the redshift of astronomical objects: usually galaxies, but sometimes other objects such as galaxy clusters or quasars. Using Hubble's law, the redshift can be used to estimate the distance of an object from Earth. By combining redshift with angular position data, a redshift survey maps the 3D distribution of matter with…

WebThe first systematic redshift survey was the CfA Redshift Survey of around 2,200 galaxies, started in 1977 with the initial data collection completed in 1982.
