A blood moon occurs when the moon is in a total lunar eclipse. It has no real significance; however, it does give the moon a red-tinted look. This can only happen during a full moon when the sun is fully illuminated against the moon’s surface.

Referred to as a "blood moon" because of its reddish and orange hue, this is North America's lone total lunar eclipse of 2025, according to NASA. Local astronomy experts say New Yorkers should have a good view of the eclipse so long as the weather cooperates and don't mind staying up late to see it.
