Part 2: The Light from Stars Contains Information. The core of a star is very hot (-15 x 10° K), and very hot objects glow. The light produced by a star's core contains all the colors in the spectrum. Astronomers can learn many things about a star's motion, temperature, and composition by analyzing the starlight that reaches Earth. A spectroscope is an instrument that separates light into its spectrum. One of the earliest uses of the spectroscope was to analyze light coming from astronomical objects. The light directed from a telescope through a spectroscope produces an KH h9 G F b E Te d h C h С B A 450 500 600 700 400 image called a spectrograph. Figure 3 shows a spectrograph of the Sun. Wavelength (nm) Figure 3 A spectrograph of the Sun. Note: The lettered lines represent different elements. Lines A and B are due to terrestrial oxygen and are not due to the Sun. 2. What do the dark lines in Figure 3 indicate? 3. Predict what happens to light as it travels from the core of the Sun to the surface? 4. Where do you think the elements in the outer layers of the Sun come from?
