Answer :

Final answer:

Kepler spacecraft uses cameras to monitor star brightness for exoplanet discovery.


Explanation:

Kepler spacecraft uses cameras to monitor the brightness (magnitude) of stars. These cameras are essential for detecting tiny variations in brightness caused by exoplanets passing in front of stars, a method known as the transit technique. Kepler's precise measurements enabled the discovery of thousands of exoplanets within its field of view.
