Star Colors and Pinyon Pine
Explanation: Beautiful, luminous decorations on this pinyon pine tree are actually bright stars in the constellation
Scorpius and the faint glow of the central Milky Way. Captured in June from the north rim of the
Grand Canyon of planet Earth, the shallow, close focus image has rendered pine needles on the tree branch sharp, but blurred the distant stars, their light smeared into remarkably colorful disks. Of course, temperature determines
the color of a star. Most of the
out-of-focus bright stars of Scorpius show a predominately blue hue, their surface temperatures much hotter than the Sun's. Cooler and larger than the Sun, and noticably redder on the scene, is giant star
Antares at the heart of the scorpion. In focused, telescopic views the whitish disk at the upper right would be immediately recognizable though, reflecting the Sun's light as ringed
gas giant Saturn.
