This Day in Science History - April 17 - Giovanni Riccioli

The Moon has its own unique geography. We have names for the smooth dark areas like Mare Serenitatis and Mare Tranquillitatus, otherwise known as the Sea of Serenity and Sea of Tranquility. The craters have names like Tycho, Copernicus and Archimedes.

One man is largely responsible for these names, Giovanni Riccioli celebrates his birthday today. Riccioli was one of the most prominent astronomers of his time and created a detailed atlas of the Moon. His names for the Maria and craters have lasted to current times.
