Depending on where you were in the world on Sept. 7, a reddish-orange "blood moon" may have filled the sky.
But there's nothing to fear, as the phenomenon is part of the cycle of a total lunar eclipse.
According to NASA, the red glow of the moon is created when the "Earth lines up between the Moon and the Sun, hiding the Moon from sunlight."
When that takes place, the only light that reaches the moon's surface comes from the edges of our planet's atmosphere. So instead of the blue hues that we're used to seeing on the moon, skywatchers instead see a glow of red on its surface, giving it the appearance of a blood moon in the night sky.
Even if you weren't in Africa, Europe, Asia or Australia, which had optimal visibility during the totality of the eclipse on Sept. 7, you can still see some of the beautiful and breathtaking scenes witnessed in the sky by scrolling through the photos below.
