At the University of Chicago since 1955, Eugene N. Parker (b. 1927) is an authority on solar wind and the effects of magnetic fields in the heliosphere. He proposed models for the solar wind based on observations of comet tails and then saw spacecraft go out and confirm his models.Naming citation (20040306/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
