Nebula (cloud of dust) composed from data from NASA's Spitzer Space Telescope using the Infrared Array Camera (IRAC). Colours correspond to wavelengths of light 3.6 (blue), 4.5 (green), 5.8 (orange) and 8.0 (red) microns. A second nebula is located at lower right. At left, a dark filament runs horizontally through the green cloud. A smattering of young stars (red and yellow dots) appear inside it. Known as Cepheus C, the area is a particularly dense concentration of gas and dust where infant stars form. This region is called Cepheus C because it lies in the constellation Cepheus, which can be found near the constellation Cassiopeia. Cepheus-C is about 6 light years long, and lies about 40 light-years from the bright spot at the tip of the nebula. Also found in the second nebula is a small cluster of newborn stars that illuminates the dense cloud of gas and dust where they formed, appearing as a bright teal splash. | |
