APOD: 2026 August 25 – Earth’s Shadow Visualized with Lunar Eclipses

NASA Science's Astronomy Picture of the Day on Tuesday highlights a composite built from twenty-two years of lunar eclipses. The image reveals Earth's full shadow, a circular dark region in space — not a black hole, but the planet's own silhouette. It also shows a faint blue band where Earth's atmosphere filters out more red sunlight than blue. A new lunar eclipse is set for later this week, with the best views in parts of North and South America, Europe, and Africa.
