Emails pop up then disappear from inbox - Microsoft Community That light always beams onto Earth and Moon from the direction of the Sun, illuminating half of our planet in its orbit and reflecting off the surface of the Moon to create moonlight. The team saw an increase in sulfate aerosols (a component of volcanic ash) in both cores between A.D. 1108 and A.D. 1110, suggesting that the stratosphere was sprinkled with fumes from a recent eruption. The moon is above your horizon and in your sky for about 12 That light always beams onto Earth and Moon from the direction of the Sun, illuminating half of our planet in its orbit and reflecting off the surface of the Moon to create moonlight.
