SDSS Galaxies

Caption

A collection of galaxies from the Sloan Digital Sky Survey. Red galaxies composed of older stars are more luminous; the recent study used a sample of 70,000 red luminous galaxies to combine galaxy clustering, weak gravitational lensing, and redshifts to compare and test competing theories of gravity.
