About The Data
Data Description The HST observations include those from programs (B. Peterson)

Filters F350LP, F555W, F814W
About The Image
Color Info These images are a composite of separate exposures acquired by the WFC3 instruments on the Hubble Space Telescope. Several filters were used to sample narrow 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: Luminosity: F350LP Cyan: F555W Orange: F814W
Compass Image Hubble telescope image of an oval-shaped spiral galaxy with a bright central core surrounded by spiral arms. The arms consist of wispy brown dust and bright mostly bluish stars.
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.
