- Instrument
- HST>ACS/WFC
- Exposure Dates
- 2005 - 2006
- Filters
- F435W (B) F555W (V), and F814W (I)
About The Image
- Color Info
- This image is a composite of separate exposures acquired by the ACS/WFC instrument. Several filters were used to sample various wavelengths. The color results from assigning different hues (colors) to each monochromatic (grayscale) image as follows: Blue: F435W (B) Green: F555W (V) 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.
About The Data
- Data Description
- Proposal: 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.
- Instrument
- The science instrument used to produce the data.
- Exposure Dates
- The date(s) that the telescope made its observations and the total exposure time.

- The camera filters that were used in the science observations.
About The Image
- Color Info
- A brief description of the methods used to convert telescope data into the color image being presented.
- Compass and Scale Image
- An 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.
