Forget the tip: This pretty blue chunk is the bottom of the iceberg
 

Need your interesting science picture fix for the day? Check out this image of a “bottom berg,” from a chunk of ice that has separated from the lower part of a glacier. A slow melt altered this iceberg’s balance in the water, making it flip and revealing its blue rear end. You might typically think of ice and icebergs as white, but that color occurs because of tiny air bubbles trapped within it. Ice from the bottom of glaciers and icebergs has been compressed for millennia, and resulting lack of bubbles turns it a rich shade of blue. Pretty sweet, right? However, it is unclear whether this particular iceberg is responding to global warming by mooning us all. [Source]

Have you ever seen an iceberg in person?
