The eclipse has begun! Today (Aug. 12), the new moon swoops in front of the sun, casting its dark shadow across a stretch of Earth from Iceland and Greenland to northern Spain. Viewers in the path of the shadow, known as the path of totality, will see a stunning total solar eclipse.
Meanwhile, millions of skywatchers in North America and Europe will be treated to a partial eclipse, with the moon covering more than 90% of the sun's visible surface in some areas.
NASA is live-streaming the entire event from Iceland and Spain. Their stream begins at 1:15 p.m. EDT, and you can watch it right here:
