This false-color mosaic of the central region of the Coma cluster combines
infrared and visible-light images to reveal thousands of faint objects
(green). Follow-up observations showed that many of these objects, which
appear here as faint green smudges, are dwarf galaxies belonging to the
cluster. Two large elliptical galaxies, NGC 4889 and NGC 4874, dominate
the cluster's center. The mosaic combines visible-light data from the
Sloan Digital Sky Survey (color coded blue) with long- and
short-wavelength infrared views (red and green, respectively) from NASA's
Spitzer Space Telescope.
