SUNSHINE IN MY EYES

Vibrant brown and orange--just like a mid-decade knit polyester shirt--these solar portraits snapped from Skylab, the first U.S. manned observatory, allowed the outer corona of the sun to be seen clearly for the first time. This picture is color-coded by brightness; others documented the constant flickering of the corona and clarified the relationship between coronal holes and high-speed streams in solar wind.
