About The Object
Object Name Orion Nebula, M42, NGC 1976
Object Description Emission Nebula
R.A. Position 05h 35m 17.0s
Dec. Position -5° 23' 27.99"
Constellation Orion
Distance The distance to the Orion Nebula is 1,500 light-years (460 parsecs).
Dimensions The color image is 7.9 arcminutes (3.4 light-years or 1.1 parsecs) wide.
About The Data
Data Description The Hubble image was created from HST data from proposal : M. Robberto (/), and , M. Robberto (/)
Instrument HST>ACS/WFC, HST>WFC3/IR
Exposure Dates Oct. 2004 – Apr. 2005 (ACS), and Feb. 2015 – Oct. 2015 (WFC3/IR)
Filters ACS/WFC: F435W (B), F555W (V), and F775W (i) WFC3/IR: F139M
About The Image
Color Info 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) Red: F139M

About The Object
Object Name A name or catalog number that astronomers use to identify an astronomical object.
Object Description The type of astronomical object.
R.A. Position Right ascension – analogous to longitude – is one component of an object's position.
Dec. Position Declination – analogous to latitude – is one component of an object's position.
Constellation One of 88 recognized regions of the celestial sphere in which the object appears.
Distance The physical distance from Earth to the astronomical object. Distances within our solar system are usually measured in Astronomical Units (AU). Distances between stars are usually measured in light-years. Interstellar distances can also be measured in parsecs.
Dimensions The physical size of the object or the apparent angle it subtends on the sky.
