Exactly two weeks after the "blood moon" total lunar eclipse comes a partial solar eclipse visible to some in North America. Here's when and where to sse it.

Firefly's Blue Ghost witnessed Earth blocking out the Sun from its point of view on the Moon, while we experienced a lunar eclipse on Earth.

In contrast, during a total solar eclipse — which is preceded by a partial eclipse — the moon completely covers the sun, revealing the sun's outer atmosphere, called the corona, during totality. That's the only time it's safe to look at a solar eclipse with the naked eye, since all of the sun's light is blocked.
