Faint Images of the Radio Sky at Twenty-Centimeters, or FIRST, was an astronomical survey of the Northern Hemisphere carried out by the Very Large Array. It was led by Robert H. Becker, Richard L. White, and David J. Helfand, who came up with the idea for the survey after they had completed the VLA Galactic Plane survey in 1990,[1] as well as Michael D. Gregg and Sally A. Laurent-Muehleisen.[2] The survey was started 50 years after the first systematic survey of the radio sky was completed by Grote Reber in April 1943.[3]
