This is another "Twitter Find," thanks to Vine Company which I think is adorable. I think it makes a great first page for students as they learn about Pluto. They also have some fantastic celebration shots, so click on the Vine to catch the party.
Now lets take another look at Charon ~ same picture, but added information:
A Mountain and a Moat
I think the caption says it all. This interesting feature has the scientist wondering how this mountain formed. Notice the few craters seen. Charon was expected to have many craters, and here we see a few. NASA will release new images tomorrow at 1:00 pm ET
