Don't ask me why I was on NASA's Jet Propulsion website but I came across a really interesting page there: "...This is neither an impact crater nor a volcano. It is a perfect circular intrusion, about 10 km in diameter..."
Is anyone else out there thinking, 'this is the weirdest thing on this planet, why haven't I heard of it?' If so, you're not alone.
