Imaging

Inspired by FLIR Systems scientist Austin Richards’ recent book, “Alien Vision,” I decided to see if I could put together my own imaging-based tour of the electromagnetic spectrum using web-based resources. This post is the result. Here are 17 striking images from across the spectrum at wavelengths ranging from one meter down to one-trillionth of a meter, from radio waves to gamma rays, arranged in order of increasing frequency / energy. Each is accompanied by a caption identifying the instrument used to record the image, the approximate wavelength at which it was recorded, the subject, and a link for those seeking more information.
