A total solar eclipse happens when the Moon passes between the Sun and Earth, completely blocking the face of the Sun. If you're lucky enough to be in the center of the Moon's shadow when it hits Earth, you'll experience a total eclipse, where the sky darkens as if it were nighttime. Experience this phenomenon LIVE with @Discovery and Science Channel's livestreams on YouTube, X, and Facebook or watch on Science Channel. It all starts at 2:15p ET/1:15p CT on Monday, April 8! #TotalSolarEclipseLIV
