The moon is passing by the Pleiades star cluster. The Pleiades star cluster is an open cluster located 497 light-years (a light-year is the distance light travels in a year, approximately 9.46 trillion kilometers) from Earth. An open cluster is defined as a group of several young stars. This cluster is primarily observed as having a blue hue.
The Pleiades star cluster also has another name known as "the seven sisters." This name comes from a story in Greek mythology where Zeus elevated the seven daughters of Atlas to the stars in the sky to protect them from hunters. The Pleiades star cluster is known to have served as a guide for ancient travelers, as it can be observed with the naked eye in the dark night sky.
