An enamel pin of a telescope with The Pleiades star cluster captured in its lens. This star cluster is also known as the seven sisters, and called Subaru in Japanese. Yes, it's why the logo for the Subaru car brand is seven stars! This star cluster is one of the brightest in our night sky and can be seen with the naked eye. However, it contains far more than the 7 stars we can see unaided. Galileo Galilei was the first to observe this star cluster through a telescope and shared his findings in 1610 that there were at least 36 stars in it!
