About The Data
Data Description The image was created from Hubble data from proposal : R. O'Connell (University of Virginia), B. Balick (University of Washington), H. Bond (STScI), D. Calzetti (University of Massachusetts), M. Carollo (Swiss Federal Institute of Technology, Zurich), M. Disney (University of Wales, College of Cardiff), M. Dopita (Australian National University), J. Frogel (Ohio State University Research Foundation) , D. Hall (University of Hawaii), J. Holtzman (New Mexico State University), P. McCarthy (Carnegie Institution of Washington), F. Paresce (European Southern Observatory, Germany), A. Saha (NOAO/AURA) , J. Silk (University of Oxford), A. Walker (NOAO/CTIO) , B. Whitmore (STScI), R. Windhorst (Arizona State University), and E.

Instrument HST>WFC3/UVIS
Exposure Dates August 19-26, 2009, Exposure Time: 11 hours
Filters F336W (U), F555W (V), F502N ([O III]), F657N (H-alpha), and F814W (I)
About The Image
Color Info The image is a composite of separate exposures made by the WFC3 instrument on the Hubble Space Telescope. Five filters were used to sample broad and narrow wavelength ranges. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are: Blue: F336W (U) Green: F555W (V) Cyan: F502N ([O III]) Red: F657N (H-alpha) + 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.
