This week, as summer leans toward autumn, the moon will pass through Earth's own shadow — a quiet cosmic reminder that we share a solar system, not merely a planet. On the night of August 27 into August 28, a partial lunar eclipse will darken nearly 96 percent of the moon's face for some 3.3 billion people across the Americas, western Europe, and western Africa, turning its edges a deep, atmospheric copper. No special equipment is required to witness it — only the willingness to look up.
