This image composite outlines the region near Orion's sword that was surveyed by NASA's Spitzer Space Telescope (white box). The Orion nebula, our closest massive star-making factory, is the brightest spot near the hunter's sword.
This image composite shows a part of the Orion constellation surveyed by NASA's Spitzer Space Telescope. The shape of the main image was designed by astronomers to roughly follow the shape of Orion cloud A, an enormous star-making factory.
NASA's Spitzer Space Telescope and the National Optical Astronomy Observatory compare infrared and visible views of the famous Orion nebula and its surrounding cloud, an industrious star-making region located near the hunter constellation's sword.
This image from NASA's Spitzer Space Telescope shows the Orion nebula, our closest massive star-making factory, 1,450 light-years from Earth. The nebula is close enough to appear to the naked eye as a fuzzy star in the sword of the constellation.
