The Mormon Church is reminding its 15 million members that just because a supermoon and lunar eclipse are happening simultaneously tomorrow night doesn't mean the world as we know it is ending, the AP reports.

Regardless, emergency-preparedness stores in Utah have seen surging sales ahead of tomorrow's so-called "blood moon" and the apocalypse it may or may not herald.
