will get to witness the lunar eclipse this weekend, half the world won’t, because it will be daytime, Speck said. While about two solar and two lunar eclipses take place every year, not everyone is in the right place on the planet to view each one, Speck said.
“Most of the solid earth is in the way of the light … so you’re basically seeing the light of gray every sunset and sunrise on the planet, reflected off the moon.” “You’re only seeing the sunlight that’s going to the edges of the earth,” she said. The reflected light refracts through the earth’s atmosphere like a prism, and gives the moon a reddish coloring, Speck explained. Once the moon is completely in shadow the sun’s light bends around the earth and reflects off the moon’s surface, then bounces back, visible to those on the planet’s night side. “But as the moon gets completely eclipsed, we see it’s basically the light that is passing through the earth’s atmosphere.” “That’s one of the reasons we’ve known the earth is round for a really long time,” Speck said. During this process, the moon still looks white.
