The total solar eclipse in North America is finally underway. Over the next several hours, day will turn into night for nearly 44 million people across Mexico, the U.S. and Canada as the moon crosses in front of the sun, blocking all sunlight for a precious few minutes.
If you can't make the event in person — or want to see a zoomed-in view of the partial and total phases of the eclipse — you can tune in to NASA's live webcast of the rare celestial event right here on Live Science, starting at 1 p.m. ET.
