Total solar eclipses, corona and all
Set a location on Earth and move the clock through an eclipse. The relative sizes of the Sun and Moon determine whether the view is partial, annular, or total. Switch to space to follow the Moon's shadow across Earth.
Lunar eclipses & the blood moon
For a lunar eclipse, the model shows Earth's umbra moving across the Moon and the red color seen during totality. Timing is calculated for the location you choose.
