Parallel Field Image of Abell S1063

Parallel Field Image of Abell S1063
Hubble observed galaxy cluster Abell S1063 with the Advanced Camera for Surveys (ACS) using visible-light filters. Simultaneously, Hubble was able to observe a field parallel to Abell S1063 with the Wide Field Camera 3 (WFC3) using infrared filters. Six months later, the observations were reversed such that WFC3 infrared observations were taken of Abell S1063, while ACS visible-light observations were made on the same parallel field. Together, the ACS and WFC3 filters combine to produce a deep image of both fields. Here, the parallel of Abell S1063 is strewn with galaxies of all shapes and sizes. The Hubble Frontier Field parallel images are a "two-for-the-price-of-one" efficient way to use the telescope to learn more about the early universe.

About the Object

  • R.A. Position
    R.A. PositionRight ascension – analogous to longitude – is one component of an object's position.
    22h 49m 17.69s
  • Dec. Position
    Dec. PositionDeclination – analogous to latitude – is one component of an object's position.
    -44° 32' 43.8"
  • Constellation
    ConstellationOne of 88 recognized regions of the celestial sphere in which the object appears.
    Grus
  • 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 billion light-years (1.2 billion parsecs)

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/IR and ACS/WFC instruments. 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: ACS/WFC F435W (B) + F606W (R) Green: ACS/WFC F814W (I) + WFC3/IR F105W (Y) Red: WFC3/IR 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.
