Solar Eclipse 2015 Kicks Off a Day of Celestial Events

The eclipse featured the new moon completely covering the sun.

This is the world's first total solar eclipse since November 2013. A partial solar eclipse was also visible in most of Europe.

The moon will also reach perigee on Friday, the point where it is closest to the Earth, creating a supermoon -- albeit a dark one -- that will add another element to the total solar eclipse.

Get ready for spring if you live in the northern hemisphere.

The official start of spring, the vernal equinox, will be marked on Friday at 6:45 p.m. ET when the Earth's axis lines up perpendicularly to the sun's rays -- marking one of the two equinoxes that occur each year.
