A lunar eclipse will pass over the state Friday night, beginning around 11 p.m. CDT or midnight ET. The peak, which will create a blood moon, is expected at 1:26 a.m. CDT or 2:26 a.m. ET.

This astrological event can only occur when the moon is full and perfectly aligned with the Earth and the sun.

A cloudy evening may inhibit your view of the night sky. Here’s a look at how the science of lunar eclipses works.
