Mercury's mysterious 'darkness' revealed
Laurel MD (SPX) Mar 09, 2016
Scientists have long been puzzled about what makes Mercury's surface so dark. The innermost planet reflects much less sunlight than the Moon, a body on which surface darkness is controlled by the abundance of iron-rich minerals. These are known to be rare at Mercury's surface, so what is the "darkening agent" there? About a year ago, scientists proposed that Mercury's darkness was due to carbon that gradually accumulated from the impact of comets that traveled into the inner Solar System. Now scie ... read more
