Total Lunar Eclipse on Sunday Night.

On May 15, at approximately 9:11 p.m. PT, the Earth will pass between the sun and the moon, resulting in a shadow or eclipse on the lunar surface. For us little earthlings, that means our normally bright moon will take on a dark, coppery look.

According to NASA, eclipse seasons generally last about 35 days and occur around every six months. Lunar eclipses only happen when a full moon pops up during an eclipse season and everything is in the right place. The last total lunar eclipse was almost one year ago, on May 26, 2021.
