This image shows a giant star-forming region in the southern sky known as the Carina Nebula (NGC3372), 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. The Carina Nebula is a good example of how very massive stars rip apart the molecular clouds that give birth to them.
