Supermoons occur when the moon is at its closest approach to Earth, making it appear brighter and bigger in the night sky than usual.
Although this supermoon is known as a pink moon, it is not actually pink in color. As the first supermoon of spring, it gets its name from a native North American wildflower that blooms in early spring: Phlox subulata, known as "moss pink."
As well as the professionals, budding photographers and supermoon fans around the world took to social media to share their best snaps.
There are typically 12 full moons a year -- one a month. But in 2020, there will be an extra full moon, with two in October -- one on October 1 and one on October 31.
Astronomers expect there to be up to four supermoons in 2020, with the next due to appear on May 7.
