The new astronomers were interested in what heavenly bodies were. They used a diverse complement of instruments that conveyed different types of information about the objects in space. The new astronomers quickly found that the photographic equipment and other instruments just becoming available gave them more information about the make-up of the sun. For example, these astronomers found that longer exposure times for photographs permitted the photographic "eye" to see many more stars than those visible to the human eye. 

Compare the images from the traditional and the new astronomy. How does the visual language convey the scientific content of each type of astronomy and what can you tell about the scientific content of each type just from the images?
