About The Data | |
Data Description | The image was created from Hubble data from proposal : S. Baum and C. O'Dea (Rochester Institute of Technology) and J. Stoke and F. Lo (Associated Universities, Inc.). Notes:The VLA data are from the National Radio Astronomy Observatory observation project TDEM0011: R. Perley, W. Cotton, and U. Rao (NRAO/AUI/NSF). These data were taken August 2010 through September 2011. Frequencies 4-9 GHz were measured. |
Instrument | HST>WFC3/UVIS |
Exposure Dates | October 8, 2012, Exposure Time: 1 hour |
Filters | F606W (V) and F814W (I) |
About The Image | |
Color Info | This image is a composite of separate exposures acquired by Hubble's WFC3 instrument. Several filters were used to sample various wavelengths/frequencies. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are: Orange: F814W (I) Blue: WFC3/UVIS F606W (V) |
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. |
