The universe is a chaotic place, but it's governed by some pretty clean rules (we just don't know them yet). As such, all the chaos can sometimes creates something "too perfect" to be real.
Case in point is the Taranaki volcano in New Zealand. Seen from above, it's almost perfectly circular, a shape you wouldn't believe could simply occur in nature.
Obviously, not that many of us get to see it from above, but since we've got a few people flying around our planet all the time and, it seems, they have plenty of time to kill, we get photos like the one above.
It's probably no surprise to anyone that this too comes from Canada's Chris Hadfield, who has been keeping us entertained ever since he boarded the International Space station with astonishing photos, live duets and nail clipping tutorials.
Needless to say, we'll be getting plenty of great photos like this for the few more months Hadfield has left aboard the ISS.
