Learn how two early-20th-century astronomers first saw patterns in the rich diversity of stars in this informative poster from Astronomy magazine.
Scan the night sky, and you'll see stars of every hue. The dazzling blue of Rigel contrasts with the ruddy glow of Betelgeuse, and neither would be confused with the pure white of Sirius or the yellow gleam of Capella. Even faint stars, when magnified by a telescope, show a range of colors. Learn how astronomers today understand stellar diversity with the Hetzsprung-Russell (H-R) diagram, named after the scientists who plotted the intrinsic brightness of stars against temperature (which determines color).
