Answer to Question 2

Photographic plates can detect faint objects in long time exposures and can be stored for later analysis. Electronic cameras exploit CCDs which are specialized computer chips containing millions of light detectors arranged in an array. These CCDs are more sensitive than photographic plates and, unlike photographic plates, they can detect bright and faint objects in a single exposure. CCD images are digitized, so they can be stored for later analysis, like photographic plates, but the data is easier to manipulate using a computer when it is digitized.
