What does a total solar eclipse look like from space
From space, a total solar eclipse appears as a dark circular patch moving across the Earth's surface. This patch is the moon's shadow, which plunges a narrow band of Earth into darkness. The rest of Earth remains illuminated by the sun.

Since spacecraft are above Earth's atmosphere, they are not subject to the same viewing limitations as observers on the ground. This means that astronauts can see the entire eclipse, including the sun's corona, the faint outer atmosphere that is normally hidden by the sun's bright face. The corona is visible during a total solar eclipse because the moon completely blocks the sun's bright surface.
