Space photos of the day: Looking deeper

Image 9 of 17


This side-by-side comparison image shows the Spitzer Space Telescope's Delta II rocket in the late afternoon before launch. On the top is a photograph in visible light, while on the bottom is a false color infrared image showing the launch vehicle in the way the telescope would see it. The coldest surfaces in the infrared image are blue/black while the hottest ones are yellow/white. The comparison between these two images reveals many interesting features of infrared light.
