A NASA observatory witnessed an incredible double eclipse this week when the Earth and the moon crossed in front of its view of the sun.
Video and images recorded Thursday by the Solar Dynamics Observatory show the Earth completely eclipse the sun just as the moon begins to cross into view. As the Earth eclipse ends, the SDO footage captures the final stages of the lunar eclipse as well.
NASA explains how to tell the difference between the Earth and the moon in the images:
In the SDO data, you can tell Earth and the moon’s shadows apart by their edges: Earth’s is fuzzy, while the moon’s is sharp and distinct. This is because Earth’s atmosphere absorbs some of the sun’s light, creating an ill-defined edge. On the other hand, the moon has no atmosphere, producing a crisp horizon.
