Anyone with clear skies Saturday night saw a spectacular swollen moon, 14 percent bigger and 30 percent brighter than our satellite usually appears.
Photos abound from amateur and professional photographers, but we like this picture from NASA, showing a pink-hued moon rising above the Lincoln Memorial in Washington, D.C.
On Saturday, the moon was 221,565 miles away — the closest it's been to Earth since March 1993.
It caused higher and lower tides, which apparently led to some minor problems for ships — five vessels were stranded in the U.K. because of sandbars that were exposed in a particularly low tide.
But for the most part, the supermoon simply looked superb.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
