Partial lunar eclipse visible tonight
Archived — this story has rotated out of today’s deck. It is kept here in full.
The gist
A deep partial lunar eclipse will be visible across North America on Aug 27-28, 2026, with about 96% of the Moon covered. It's the best lunar eclipse until a total.
Background
A partial lunar eclipse occurs when Earth moves between the sun and the moon, casting its shadow on the lunar surface. This particular eclipse is unusually deep, with about 96% of the Moon's diameter entering Earth's dark umbral shadow, making it appear reddish or 'almost blood moon'. It is visible across North and South America, Africa, and Europe, and is considered the most impressive lunar eclipse until a total lunar eclipse in late 2028.
