About the Object

  • R.A. Position
    R.A. PositionRight ascension – analogous to longitude – is one component of an object's position.
    19:09:46.1
  • Dec. Position
    Dec. PositionDeclination – analogous to latitude – is one component of an object's position.
    -63:51:27
  • Constellation
    ConstellationOne of 88 recognized regions of the celestial sphere in which the object appears.
    Pavo
  • 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.
    31 million light-years
  • Dimensions
    DimensionsThe physical size of the object or the apparent angle it subtends on the sky.
    Image is 2.7 arcmin across (about 24,000 light-years)

Color Info
Color InfoA brief description of the methods used to convert telescope data into the color image being presented.

These images are a composite of separate exposures acquired by the WFC3 and ACS instruments on the Hubble Space Telescope. Several filters were used to sample narrow wavelength ranges. 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: Magenta: F275W Blue: F336W+F438W Green: F555W or F606W Red: F814W
