The full moon in April - known as the Pink Moon - lit up the skies on Tuesday night.
The Pink Moon peaked just before 4am, but astronomy experts say it actually may have an orange glow this year!
But will the Moon actually be pink?
Newsround has everything you need to know.
In many cultures, including Native American tribes, people named the full moons throughout the year as a way to keep track of time.
So although April's full moon is known as the Pink Moon, don't expect it to look particularly pink!
It's named after pink flowers called wild ground phlox, which bloom in early spring and appear throughout the United States and Canada.
It is also called the Sprouting Grass Moon, the Egg Moon and the Fish Moon in other parts of the world.
April's full moon marks important festivals and holidays for people around the world too.
Hindus celebrate the birth of Hanuman in India in a festival called Hanuman Jayanti.
The April full moon will also mark the beginning of Jewish Passover.
