science ๐ญ Shadow bands mystery resurfaces before next eclipse ๐
An eerie phenomenon called shadow bands appears before and after total solar eclipses, which scientists are still trying to understand. David Turnshek observed this near Virginia Beach in 1970, and the phenomenon features dark lines racing across surfaces. In 2017, researchers found a 4.5 hertz signal during a US eclipse, suggesting turbulence wasn't the only cause. The next total solar eclipse on Wednesday will offer a chance to study this mystery further. However, efforts during the April 8, 2024, eclipse in Concan, Texas, were hampered by cloud cover.
