Curiosity Spots a Shiny "Arm"

Curiosity Rover has once again spotted an unusual thing.

In pictures, taken by the rover, a shiny object is poking out of the rock.

Some have taken to describing it as a metal arm.

Whatever it is, it's poking about half a centimeter out of rock, just big enough to case a shadow.

It also seems to be of a different kind of material than the surrounding area.

NASA does not know what it is, nor do they seem interested in checking it out, immediately.

So for now it will remain but one more mystery.
