The new pictures show Pluto is home to a large mountain range made of water ice with peaks as high as 11,000 feet, rivaling the Rocky Mountains in size.  

They also reveal that Pluto's largest moon, Charon, has cliffs, troughs and a mysterious gash 4 to 6 miles deep that cuts across the surface, as well as vast areas of smooth terrain. 

But almost as notable from these early results is what was missing from the images: impact craters.

Researchers at the Lawrence Berkeley National Laboratory report that by 2030, a driverless taxi could lower greenhouse gas emissions by as much as 90% compared with a ride in a privately-owned gas-powered car today.

Even if you had a more efficient hybrid car of your own in 2030, the researchers calculated that a ride in an autonomous taxi would still reduce per-mile greenhouse emissions from 63% to 82%.
