About The Data
Data Description ACS/WFC data of RS Puppis were obtained as part of the HST proposal : H. Bond (STScI and Pennsylvania State University), W. Sparks (STScI), P. Kervella (Observatoire de Paris), A. Merand (European Southern Observatory), D. Bersier (Liverpool John Moores University), P. Fouque (Observatoire Midi-Pyrenees), E. Pompei (European Southern Observatory), G. Perrin (Observatoire de Paris), and V. Scowcroft (Carnegie Institution of Washington)
Instrument HST>ACS/WFC
Exposure Dates March 26, 2010, Exposure Time: 35 minutes
Filters F435W (B) and F606W (V)
About The Image
Color Info This image is a composite of separate exposures acquired by the ACS instrument on the Hubble Space Telescope (HST). Several filters were used to sample broad wavelength ranges. 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: Blue: F435W (B) Green: F435W (B) + F606W (V) Red: 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.
