Longtime Goddard astrophysicst Ted Gull gave the Goddard-wide Scientific Colloquium on April 15, 2015. This photo was taken at the COBE 25th anniversary celebration in November 2014. (Note that the photo from the original gallery has way too warm a color temperature and looks much better here after adjusting from 5150K down to 3366K. (This is due to trying to balance ambient light and flash, to avoid too-dark backgrounds.)
