The NASA/ESA Hubble Space Telescope has taken a close-up view of an outer part of the Orion Nebula's little brother, Messier 43. This nebula, which is sometimes referred to as De Mairan's Nebula after its discoverer, is separated from the famous Orion Nebula (Messier 42) by only a dark lane of dust. Both nebulae are part of the massive stellar nursery called the Orion molecular cloud complex, about 1400 light-years away, one of the closest massive star formation regions to Earth. This picture was created from images taken using the Wide Field Channel of Hubble's Advanced Camera for Surveys. Images through yellow (F555W, coloured blue) and near-infrared (F814W, coloured red) filters were combined.
