Herbig Haro 901 is a multiple light-years tall pillar of gas and dust inside the star-forming region know as the Carina Nebula. It contains several massive young stars which emit powerful jets that emerge from the cloud. Some of the jets create bow-shock patterns similar to the bow waves of a ship plowing through the ocean. Very few of these stars can be seen because the gas and dust block starlight, but in an infrared view, more stars become visible. The visible-light colors result 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.
