This Hubble image shows part of the Tarantula Nebula, a star-forming region some 163,000 light-years away in the constellation of Dorado. The color image is a composite of separate exposures acquired by Hubble’s Wide Field Camera 3 (WFC3) instrument in the ultraviolet, near-infrared, and optical parts of the spectrum. It is based on data obtained through four filters. The color results from assigning different hues to each monochromatic image associated with an individual filter.
