    Born on August 1, 1818, Maria Mitchell entered a world where her natural curiosity was embraced and encouraged by parents that believed that a girls education should be equal to a boys. She was the daughter of Quakers whose ancestors had fled to the island of Nantucket to seek refuge from the tyranny being imposed by Puritans. This background seemed to have set her family on a course for breaking social norms and led to Mitchell's immersion in the field of science - a place that had previously only welcomed male scientists.

    Notable achievements

    On an autumn night in 1847, Maria Mitchell made a discovery that would change her life. While her family was inside the house, Maria looked through a telescope on the roof and set the field of view on what she had at first presumed was a star. Her interest was immediately piqued as Mitchell had not noticed a star occupying this part of the sky before and she considered the possibility that it might be a comet. After a couple of nights of recording coordinates and observing, she was sure she had found a comet. Her father wrote to a professor at Harvard University who then sent a letter about Maria's discovery to the King of Denmark. The king had made an offer to award a gold medal to astronomers who might find a comet that relied on the use of a telescope for viewing, but someone else got credit for the find before Maria was able to be recognized.

    Father Francesco de Vico of Rome had spotted Maria's comet two nights after she did, and since he was located in Europe the news of his discovery reached the king before the professor's message got to him. After about a year, and some negotiations, Maria was deemed the comet's finder, and it was thus named "Miss Mitchell's Comet". It is this comet that propelled Maria Mitchell to fame and led to a lifetime of scientific inclusion that most women of the era were not privy to.

    Amazing facts

    So much of what Maria Mitchell accomplished in her life is colored by the fact that these were monumental feats for women at the time. Her finding of the comet made her an instant celebrity amongst the scientific community and even many people came to Nantucket to witness "the woman astronomer". The offers began pouring in, and Maria had the opportunity to travel to Europe. Because of her notiarity she was the first woman able to gain access to the Vatican's observatory; although she was only allowed to observe during the day, this was still considered quite a big deal at the time.

    Her contributions to the science and women's rights have left an indelible impression that has significantly shaped astronomy and the viewpoint that women are just as mentally substantial thinkers as their male counterparts.
