A Total Solar Eclipse Feels Really Really Weird | WIRED

A great account of what to expect during this month’s solar eclipse.

Have you ever witnessed a total solar eclipse? Usually when I give a lecture, only a couple of people in an audience of several hundred people raise their hands when I ask that question. A few others respond tentatively, saying, “I think I saw one.” That’s like a woman saying, “I think I once gave birth.”

What these people are remembering is some long-ago partial solar eclipse. These are quite common. They occur every few years in various places across the globe. But believe me, if you’ve seen a total solar eclipse—when the moon passes directly between the sun and the earth—you’ll never forget it.

Part of what makes a total eclipse so breathtaking has to do with invisible light. During the “moment of totality”—the minutes when sun is completely blocked—observers experience the exquisitely odd and wondrous sensation of solar emissions, both visible and invisible, vanishing right in the middle of the day.
