About the Object

  • R.A. Position
    R.A. PositionRight ascension – analogous to longitude – is one component of an object's position.
    12h 6m 11.97s
  • Dec. Position
    Dec. PositionDeclination – analogous to latitude – is one component of an object's position.
    -8° 48' 0.03"
  • Constellation
    ConstellationOne of 88 recognized regions of the celestial sphere in which the object appears.
    Virgo
  • 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.
    4.5 billion light-years (1.2 billion parsecs)

Compass and Scale Image of CLASH Image
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 many separate exposures made by the ACS and WFC3 instruments on the Hubble Space Telescope using ten different filters. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are: Blue: ACS/WFC F606W (V) + F625W (r) Green: ACS/WFC F775W (i) + F814W (I) + F850LP (z) Red: WFC3/IR F105W (Y) + F110W (YJ) + F125W (J) + F140W (JH) + F160W (H)

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.
