This is my first image that I’ve processed from the Spitzer Space Telescope. This telescope is an infrared telescope launched in 2003. This image is of NGC 6357, a diffuse Nebula that can be seen in the constellation Scorpius. NGC 6357 is known as a HII region, which is a region where hot young stars strip electrons from neutral surrounding gas forming clouds of ionized hydrogen, thus H two. I processed this image from 4 wavelengths in the Infrared spectrum. Since it’s all Infrared and not visible to the naked eye, I had to guess on the colors to make each of the 4 layers to make a pleasing looking image. Image credit NASA/JPL-Caltech.
