...actually, it's a pellet of “dry ice” floating on a shallow bed of dark blue water and shooting off geysers of carbon dioxide as it warms up. The dry ice is solid CO2 which sublimates directly to gas as it warms up (skipping the liquid phase altogether).

It is mesmerizing to watch. Particles glide along the surface, spin, and merge when they touch. Here is a very cool video of the icy bodies spinning and shooting around.

    A 'good' foto should be 'fun' to look at (sez I). This one certainly is fun! Though I'm slightly disappointed that it's not really a foto of where we are in this galaxy...

    I liked the photos too. They are so abstract, and I like the science behind them. Thanks for putting in the link to the video as well.

    Thanks for the link to the "portable coments exhibit machine"! I'm using that film, together with a computer simulated comet, in order to teach kids what comets really are!
