Stephan’s Quintet

Galaxy group Stephan's Quintet is located in the constellation Pegasus.

About the colours

The image is a composite of separate exposures made by the WFC3 instrument on the Hubble Space Telescope. Six 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: F438W (B) Green: F606W (V) Red: F140W (JH) + F657N (H-alpha + [N II]) + F665N (H-alpha + [N II]) + F814W (I)

About the data

The Hubble images were created from data from proposal 11502 : K. Noll and M. Livio (STScI), D. Leckrone and M. Niedner (NASA/GSFC), and Z. Levay and M. Mutchler (STScI).
