Before a total solar eclipse, shimmering ghost bands race across the ground. A new discovery reveals this is a giant double-slit experiment, with the Sun's edges acting as the slits. Solving the centuries-old mystery not only explains the phenomenon but also provides a way to probe the atmosphere.

🎯 The earliest descriptions of shadow bands are found in Chinese chronicles from 2000 BCE, yet the explanation didn't come until the 21st century.
