(AP) — NASA's New Horizons spacecraft is now halfway between Pluto and its next much, much smaller stop. New Horizons — which reached the milestone this week — is bound for an even more remote object called 2014 MU69. Like Pluto, the object orbits in our solar system's twilight zone known as the Kuiper Belt, but is barely 1 percent its size. MU69 is near...

Deposits of ice have previously been spied in craters on Mercury and our moon, also in regions that are permanently in the dark. The discovery comes from pictures taken by NASA's Dawn spacecraft, which has been in orbit for ov...

(AP) — The deep icy basin in Pluto's heart-shaped region may be a natural sinkhole. In a study published Wednesday, a team led by University of Maryland astronomer Douglas Hamilton suggests the basin may have resulted from the weight of surface ice. Computer modeling by the researchers indicates an ice cap formed at... Wed, 30 Nov 2016 19:52:00 GMT 2016-11-30T19:52:00Z
