Maria Mitchell

Maria Mitchell (1818–1889) was a 19th-century American astronomer. The single most important thing about her is that she showed girls could be first-rate scientists. Her big moment was finding a moving 'fuzzy star' from her home on Nantucket — a comet that made her famous and noticed by scientists everywhere.

When she found the comet, she won international honors, including a gold medal from the King of Denmark, and became one of the first American women to work as a professional astronomer. In 1865 she became professor of astronomy at Vassar College, set up telescopes and an observatory for students, and taught many young women to study the stars.

Today her name lives on in museums and observatories that inspire kids to look up and ask, "What will I discover?"
