Exact moonlight measurements could aid Earth-observing missions
27 November 2017
A new telescope's unprecedented study of subtle variations in lunar light could finally give Earth-facing satellites a common reference point for their observations.
As our nearest neighbor in space, the Moon is one of the most familiar objects in our sky. Yet there are still things we don't know about it—like exactly how bright it is. In a new project, scientists will seek to make the most accurate measurements to date of lunar irradiance, the amount of light coming from the Moon.
