- "The Basics of a Solar Eclipse: What You Need to Know"

The Moon is having its day in the Sun — happy solar eclipse 2024! Today, the Moon crosses between the Sun and the Earth, effectively blocking the Sun’s light. In the path of totality, the sky will darken, the air will cool, and the Sun’s glowing corona (its rarely seen outermost part) will become visible for up to four and a half minutes! People in North America (Mexico, the United States, and Canada) get to witness a special and rare event — a partial eclipse or total eclipse if they are in the path of totality. Visit NASA’s 

livestream to watch the event live from 1-4 p.m. ET.
