About the Object

  • R.A. Position
    R.A. PositionRight ascension – analogous to longitude – is one component of an object's position.
    23h 20m 48.3s
  • Dec. Position
    Dec. PositionDeclination – analogous to latitude – is one component of an object's position.
    61° 12' 6.12"
  • Constellation
    ConstellationOne of 88 recognized regions of the celestial sphere in which the object appears.
    Cassiopeia
  • Distance
    DistanceThe 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.
    7,100 light-years (2,100 parsecs)

The Bubble Nebula with compass and scale
Color Info
Color InfoA brief description of the methods used to convert telescope data into the color image being presented.

This image is a composite of separate exposures acquired by the WFC3/UVIS instrument. Several filters were used to sample various wavelengths. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are: Blue: F502N ([O III]) Green: F656N (H-alpha) Red: F658N ([N II])

Compass and Scale
Compass and ScaleAn astronomical image with a scale that shows how large an object is on the sky, a compass that shows how the object is oriented on the sky, and the filters with which the image was made.
