It happens when a total lunar eclipse, a blood Moon and a supermoon coincide.

A blue moon occurs when a full moon happens twice in one month, and a supermoon occurs when the Moon is closest to the Earth.

This red glow is produced by the same effect that gives us red sunsets. Sunlight is skimming through the Earth's atmosphere on its way to the Moon and it gets refracted or bent. The blue light is then filtered out, leaving the red light visible.

The rarity of the Instagram-worthy sight meant many people all over the world would wait for hours to catch a glimpse of the unique lunar eclipse.

There won’t be another “super blue blood moon” until 2037.
