Eclipses dazzled the ancient world. Now that we understand them better, they may be even more miraculous. ![A complete solar eclipse]()
On April 8th, the moonwill partly and then entirely block out the sun. The total eclipse will be visible to those in a hundred-and-fifteen-mile-wide sash, called the path of totality, slung from the hip of Sinaloa to the shoulder of Newfoundland. At the path’s midline, the untimely starry sky will last nearly four and a half minutes, and at the edges it will last for a blink. On the ground, the lunacy around total eclipses often has a Lollapalooza feel. Little-known places in the path of totality—Radar Base, Texas; Perryville, Missouri—have been preparing, many of them for years, to accommodate the lawn chairs, soul bands, food trucks, sellers of commemorative pins, and porta-potties. Eclipse viewers seeking solitude may also cause problems: the local government of Mars Hill, Maine, is reminding people that trails on Mt. Katahdin are closed, because it is mud season and therefore dangerous. I have a friend whose feelings and opinions often mirror my own; when I told her a year ago that I had booked an Airbnb in Austin in order to see this eclipse, she looked at me as if I’d announced I was bringing my daughter to a pox party.
