This image shows the Carina Nebula (NGC 3372), combining the light from 3 different filters tracing emission from oxygen (blue), hydrogen (green), and sulfur (red). The color is also representative of the temperature in the ionized gas: blue is relatively hot and red is cooler. This image was taken at the Curtis Schmidt telescope at the Cerro Tololo Interamerican Observatory.
