On Sunday evening and early Monday morning, the moon will provide stargazers a triple helping of thrills.
First, it will be the fourth “blood moon” in the past year and a half. The eclipse is said to be the last of a "tetrad," four consecutive total lunar eclipses. The others were in April and October of 2014, and last April.
“Look outside – the sky is beautifully blue [Friday]. Little bitty dust motes are scattering little bitty light waves; the blues, the violets,” said Wayne Wooten, an astronomer at Pensacola State College.
