Scale and Compass Image for Orion Nebula
Orion Nebula, M42, NGC 1976
The distance to the Orion Nebula is 1,500 light-years (460 parsecs).
The color image is 7.9 arcminutes (3.4 light-years or 1.1 parsecs) wide.
ACS/WFC: F435W (B), F555W (V), and F775W (i)
The color image is a composite mosaic of many separate exposures made by the ACS and WFC3 instruments on the Hubble Space Telescope using several different filters isolating the light of specific elements or of specific broad wavelength ranges. The color arises by assigning different hues (colors), to each monochromatic image. In this case, the colors are:
Blue: F435W (B)
Cyan: F555W (V)
Yellow: F775W (i)
