NASA is using the total solar eclipse on April 8 to increase public knowledge of science while encouraging safety during what could be a once-in-a-lifetime event.

Thanks to NASA, viewers can watch the solar eclipse as it crosses Mexico; the United States from Texas to Maine; and Canada’s Atlantic coast.

Total solar eclipses happen when the moon passes between Earth and the sun, completely blocking the sun's face. But these celestial events aren't all exactly alike.

NASA will be livestreaming the 2024 solar eclipse from several sites along the path of totality.

The total solar eclipse will, for a moment, turn day into night, briefly revealing the sun's outer atmosphere, the corona.
