PHOTO COURTESY NASA In this lunar eclipse viewed from Merritt Island, Fla., the full moon takes on a dark red color because it is being lighted slightly by sunlight passing through the Earth's atmosphere. This light has the blue component preferentially scattered out (this is also why the sky appears blue from the surface of the Earth), leaving faint reddish light to illuminate the Moon. Eclipses occur when the Sun, Earth and Moon line up. They are rare because the Moon usually passes above or below the imaginary line connecting Earth and the Sun. The Earth casts a shadow that the Moon can pass through - when it does, it is called a lunar eclipse. — NASA

Something truly out of this world is coming this weekend to a solar system near you.

For those living in North and South America, Western Europe, much of Africa and the eastern Pacific, a lunar eclipse will be visible. The moon will pass into the shadow of the Earth, and the moon will take on a reddish color. The eclipse will reach its totality around 11:30 p.m. Sunday night, May 15.

The “blood moon” effect results from the sun’s light passing through the Earth’s atmosphere and taking on different colors because of the dust and water vapor in the atmosphere.

The sky show is free and harmless to watch.
