A solar eclipse happens when the moon’s shadow falls somewhere on the surface of Earth. And a lunar eclipse is the opposite, when the Earth’s shadow falls on the moon. The two sections of the shadow, the dark umbra and the partially shaded penumbra, their placement determines which type of eclipse we can see from Earth. But not all eclipses are made equal. The most spectacular, the one for your bucket list is a total eclipse of the sun.
So in a billion years or so, whatever creatures live here will witness Earths very last total solar eclipse.
