A Narrated Tour of the Moon Although the moon has remained largely unchanged during human history, our understanding of it and how it has evolved over time has evolved dramatically. Thanks to new measurements, we have new and unprecedented views of its surface, along with new insight into how it and other rocky planets in our solar system came to look the way they do.

Evolution of the Moon From year to year, the moon never seems to change. Craters and other formations appear to be permanent now, but the moon didn’t always look like this. Learn about how the moon evolved from its early state to how it looks today in this new animation!
