Climate change may have helped to alter the course of history. A period of extreme and unprecedented cooling in the northern hemisphere 1,500 years ago may have reduced the eastern Roman empire, set the stage for a famine and a devastating pandemic that killed millions, and favored the rise of the Islamic forces that created the Arab empire. The so-called Little […]

But when NASA’s Messenger spacecraft transmitted its first optical images of the closest planets to the sun, that’s exactly what scientists discovered. Mercury sits about 36 million miles from the sun, which is roughly 57 million miles […]
