About the Data

  • Data Description
    Data DescriptionProposal: A description of the observations, their scientific justification, and the links to the data available in the science archive.
    Science Team: The astronomers who planned the observations and analyzed the data. "PI" refers to the Principal Investigator.
    This image was created from HST data from proposal 9750: K. Sahu, and H. Bond (STScI), T. Brown (High Altitude Observatory, Boulder), S. Casertano and M. Livio (STScI), D. Minniti (Catholic University of Chile), N. Panagia (STScI), A. Renzini (Astronomical Observatory of Padova, Italy), R. Rich (University of California, Los Angeles), and M. Zoccali (Catholic University of Chile). The science team also includes J. Valenti, E. Smith, T. Brown, W. Clarkson, and S. Lubow (STScI), and N. Piskunov (Uppsala University, Sweden).

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 instrument on the Hubble Space Telescope using two different filters. Two filters were used to sample broad wavelength ranges. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are: Blue: F606W (V) Green: F606W (V) + F814W (I) Red: F814W (I)

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.
