Wow! Massive Mars Ice Deposit Could Fill Lake Superior

Frozen beneath a region of cracked and pitted plains on Mars lies a hidden treasure of water, enough to fill Lake Superior, largest of the Great Lakes, to the brim. This according to researchers who used pictures and radar data from NASA’s Mars Reconnaissance Orbiter (MRO) to uncover scalloped and cracked landforms similar to those in the Canadian Arctic…

Pluto’s Heart May Throb With A Salty Ocean

Remember Pluto’s big, white, icy heart? A new study, led by Brown University geologist Brandon Johnson, says there’s a good chance that beneath that ice, there’s 62 miles (100 km) of liquid water. And it’s super salty, similar to the Dead Sea. The research focused on Sputnik Planum, a basin 560 miles (900 km) across that makes up…

Ice Goes Into Hiding On Ceres / Dawn, Pluto Probe Update

We know there’s ice inside Ceres, but it may be chillin’ on the surface, too. Scientists with NASA’s Dawn mission have identified permanently shadowed craters on the dwarf planet that have likely been cold enough to trap water ice for a billion years. “The conditions on Ceres are right for accumulating deposits of water ice,” said…

Ice Makes Pluto’s Moon Charon Split A Gut

For the same reason a glass bottle filled with water shatters when left to freeze, ice may have split Pluto’s moon Charon wide open. Ice expands when it freezes. This simple fact of physics has wide-ranging consequences from busting your water pipes during a cold spell to spalling rocks and shifting home foundations during freeze-thaw cycles. Images…

But this beautiful photo taken by Damian Peach of Rosetta’s Comet deserves to be seen by a wider audience. The photo shows the comet against a fantastic…
