They shoot out powerful jets that emerge from the cloud. In some cases, the jets create bow-shock patterns similar to the effects of a ship plowing through the ocean. In the visible-light view, very few stars can be seen because the gas and dust block starlight. But in the infrared view, stars become visible and numerous. The visible-light colors emerge from the glow of different gases: oxygen (blue), hydrogen/nitrogen (green), and sulfur (red). The Carina Nebula is approximately 7,500 light years from Earth....
