Summary
DescriptionChris Gunn, James Webb Space Telescope photographer (46741910804) (cropped).jpg |
This self-portrait of photographer Chris Gunn was made in an “air shower” before entering one of the cleanrooms where work on the James Webb Space Telescope was being performed. The “bunny suit” that he's wearing protects the telescope from contaminants like clothes, hair, and skin. Every time he has photographed the telescope he's had to put on one of these suits and clean his camera gear. Image credit: Chris Gunn |
