FIGURE 3.2 Distribution of optical and infrared telescope aperture around the world, 1990 and 2010. Colors denote the fraction of telescope primary mirror area held by U.S. private institutions (blue), U.S. federally funded national observatories (red), European-run observatories (purple), and other foreign-led observatories (green). The main change since 1990 has been a sharp decline in the share of telescope aperture available through U.S. public observatories.
