Earth photobombs the moon and the moon turns blood red out of spite.

means The event where Earth passes directly between the sun and the moon, so Earth's shadow falls across the moon's face.

from Straightforward Latin-via-Greek lineage: 'lunar' comes from Latin 'luna' meaning moon, and 'eclipse' comes from Greek 'ekleipsis' — literally a 'failing' or 'abandonment,' from 'ekleipein,' to leave out or fail to appear. To ancient skywatchers the moon seemed to simply go missing, abandoning its post in the sky, and that sense of a heavenly body 'failing' to show up gave the word its lasting name.
