A rare celestial event is happening this week.
On Thursday (April 20), the moon will block out the sun during what is known as a hybrid solar eclipse. This type of eclipse shifts from total solar eclipse to annular (ring-shaped) as the moon's shadow moves across the surface of the Earth. The last hybrid solar eclipse happened in 2013, and the next will occur in 2031. After that, future skywatchers will have to wait until March 23, 2164.
