They may look like space stations floating in vacuum, but these are actually delicate ice bubbles that formed in Ontario's Cranberry Lake. Michael Runtz took this picture of the segmented shapes created when pockets of air slowly bubble up from the bottom of the lake and get trapped in the freezing water as they move. Want to see what happens when giant ice structures are sculpted by wind?
Here you can see pictures taken by Tony Travouillon of giant chunks of ice in Antarctica that have been sculpted by the wind to look like huge waves erupting out of the ground.
You can see more beautiful ice bubbles here and here.
