The collection of red dots seen near the center of this image show one of several very distant galaxy clusters discovered by combining ground-based optical data from the National Optical Astronomy Observatory's Kitt Peak National Observatory with infrared data from NASA's Spitzer Space Telescope. This galaxy cluster, named ISCS J1434.7+3519, is located about 9 billion light-years from Earth. The large white and yellow dots in this picture are stars in our galaxy, while the rest of the smaller dots are distant galaxies. The cluster, comprised of red dots near the center, includes more than 100 massive galaxies.
