About the Object

  • R.A. Position
    R.A. PositionRight ascension – analogous to longitude – is one component of an object's position.
    00h 14m 18.89s
  • Dec. Position
    Dec. PositionDeclination – analogous to latitude – is one component of an object's position.
    -30° 23' 21.98"
  • Constellation
    ConstellationOne of 88 recognized regions of the celestial sphere in which the object appears.
    Sculptor
  • 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.
    Redshift: z=0.308

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 ACS and WFC3 instruments on the Hubble Space Telescope. Several filters were used to sample broad 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: Blue: F435W (B) + F606W (V) Green: F814W (I) + F105W (Y) Red: 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.

This diagram shows how the gravity of the massive galaxy cluster Abell 2744 bends and magnifies the faint light of a far distant galaxy behind it, a phenomenon called gravitational lensing. The cluster's lensing power produced three magnified images of the faraway galaxy,...
