This image is the winner of the “Science as art” competition. It is called nano-explosion and this is the spiel about it:

Color-enhanced scanning electron micrograph of an overflowed electrodeposited magnetic nanowire array (CoFeB), where the template has been subsequently completely etched. It’s a reminder that nanoscale research can have unpredicted consequences at a high level.

It reminds me of the Futurama episode, Godfellas, when Bender has a Lilliput race of people set up shop on his body and think he’s God. It all comes to an end when they all blow each other up in a mini nuclear war, looking not unlike the above image.
