About the Object
- R.A. PositionR.A. PositionRight ascension – analogous to longitude – is one component of an object's position.11h 49m 35.08s
- Dec. PositionDec. PositionDeclination – analogous to latitude – is one component of an object's position.22° 24' 10.94"
- ConstellationConstellationOne of 88 recognized regions of the celestial sphere in which the object appears.Leo
- DistanceDistanceThe 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.9.3 billion light-years or 2.9 billion parsecs (supernova); 5 billion light-years or 1.5 billion parsecs (cluster)
About the Data
- Data DescriptionData 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.The black and white images were created from data from HST proposal 14199 PI: P. Kelly (UC Berkeley) et al.
The science team includes: P. Kelly (UC Berkeley), S. Rodney (University of South Carolina), G. Brammer (STScI), L. Strolger (STScI/WKU), R. Foley (University of Illinois at Urbana-Champaign), T.
