About The Data
Data Description This image was created from HST data from proposal : K. Sahu, R. Gilliland, H. Bond, S. Casertano, M. Livio, and N. Panagia (STScI), T. Brown (University Corporation for Atmospheric Research), D. Minniti (Catholic University of Chile), A. Renzini (Astronomical Observatory of Padova, Italy), R. Rich (University of California, Los Angeles), and M. Zoccali (Catholic University of Chile). The science findings also include data taken with the HST proposal : K. Sahu (STScI) et al. Additional members of the science team include W. Clarkson (Indiana University and UCLA), and T. Brown, E. Smith, and J. Anderson (STScI).
Instrument HST>ACS/WFC
Exposure Dates February 22 - 29, 2004, Exposure Time: 49 hours
Filters F606W (R) and F814W (I)
About The Image
Color Info 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 (R) Green: F606W (R) + F814W (I) Red: F814W (I)

About The Object
Object Name A name or catalog number that astronomers use to identify an astronomical object.
Object Description The type of astronomical object.
R.A. Position Right ascension – analogous to longitude – is one component of an object's position.
Dec. Position Declination – analogous to latitude – is one component of an object's position.
Constellation One of 88 recognized regions of the celestial sphere in which the object appears.
Distance The 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.
Dimensions The physical size of the object or the apparent angle it subtends on the sky.
