An illustration of the Sun-Moon-Earth configuration setting up a total solar eclipse. When the Moon's shadow falls on Earth when the nearer-to-the-Sun node aligns, we get a solar eclipse. Conversely, when the away-from-the-Sun node aligns with the Earth-Sun plane, the Moon passes through Earth's shadow and gives us a lunar eclipse. The last eclipse, as of today, was January 20/21, 2019, which was a total lunar eclipse.STARRY NIGHT EDUCATION SOFTWARE
