This swirling landscape of stars is known as the North America Nebula. In visible light, the region resembles North America, but in this image infrared view from NASA’s Spitzer Space Telescope, the continent disappears. In Spitzer’s view the infrared light penetrate dust. Dusty, dark clouds in the visible image become transparent in infrared. Spitzer’s infrared detectors pick up the glow of dusty cocoons enveloping baby stars. Clusters of young stars (about one million years old) can be found throughout the image. Some areas of this nebula are still very thick with dust and appear dark. The Spitzer image contains data from both its infrared array camera and multi-band imaging photometer. This image is from February 2011.
