Mercury is not the first planet to come to mind if you were searching for ice in the solar system. After all, the surface temperature across most of the planet is hot enough to melt lead.
But at the poles on Mercury it's a different story. Almost no sun reaches the poles, and as a result, temperatures can drop to less than -100 degrees Fahrenheit. Now, three papers in the journal Science suggest there really is ice at the bottom of craters near the poles on Mercury.

These developments come after a series of rebel victories in recent days and suggest that President Bashar Assad's government is facing increased pressure from the rebels in an uprising now 20 months old.
