Because of that difference in distance, the Sun and Moon can appear surprisingly similar in size when viewed from Earth.
When the geometry lines up correctly, the Moon can pass directly in front of the Sun and produce a spectacular eclipse.
It’s a reminder of just how precisely the Earth, Moon and Sun move through space.
Today’s eclipse is not the same everywhere
If you’re seeing photos online today, don’t assume everyone is seeing exactly the same thing.
The appearance of the eclipse depends heavily on location.
Someone inside the path of totality can experience the Moon completely covering the Sun.
Someone hundreds or thousands of miles away might see only a portion of the Sun covered.
And someone outside the visibility region won’t see the eclipse at all.
That’s why eclipse maps and local viewing information are so important for today’s event.
