Object Name - Orion Nebula (M42, NGC 1976)
Object Description - Emission Nebula
Position (J2000) - R.A. 05h 35m 17s // Dec. -05° 23' 28"
Constellation - Orion
Distance - The distance to the Orion Nebula is 1,500 light-years (460 parsecs).
Dimensions - The image is 30 arcminutes (13 light-years or 4.0 parsecs) square.
Color - This image is a composite mosaic of many separate expposures made by the ACS instrument on the Hubble Space Telescope and the ESO La Silla 2.2 meter 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.
