What's so special about this photo of the Moon?

We'll give you a hint: It was taken by John W. Draper in 1839.

If you guessed that it's the first photograph ever taken of the Moon, you are absolutely correct.

Originally from England, Draper was a chemistry professor at New York University during the 1800s. This silver platinum plate of the moon was the first of a series that he shot with the assistance of a telescope. He later presented these photos to the Science Academy.
