These high resolution images of space scenes are matted to perfection on quality card-stock board and feature a description of the image on back.
This image of the Milky Way Galaxy is a digital fusion of three infrared colors. At these colors, the sky is dominated by the faint glow of very cold gas within only 500 light years of Earth. In the above image, red corresponds to temperatures as cold as 10 degrees Kelvin above absolute zero, while white corresponds to gas as warm at 40 Kelvins. The pink band across the lower part of the image is warm gas confined to the plane of our Galaxy.
