While England's Charles Darwin studied the foundations of biological science, America's Maria Mitchell became famous for her celestial discoveries. She was our nation's first professional female astronomer. Maria Popova explains: "In 1831 when she was still a teenager obsessed with stargazing she heard that the king of Denmark had offered a gold medal valued at 20 ducats, which was a lot of money at the time to the first person to discover a telescopic comet. It took her 16 years to master the science and the craft of observation, but she did become the first person and C1847T1 was known for 100 years Miss Mitchell's Comet."
