Figure 3-38 Nonvisible and Visible Radiation (a) The McMath-Pierce Solar Telescope at Kitt Peak Observatory near Tucson, Arizona (the inverted V-shaped structure), takes visible-light photographs of the Sun, such as the one shown in the inset. (b) This X-ray telescope was carried aloft in 1994 by a space shuttle. The inset shows an X-ray image of the Sun. Comparing the images in the two insets reveals how important observing nonvisible radiation from astronomical phenomena is to furthering our understanding of how the universe operates.
