Etna smolders

Mount Etna on the island of Sicily has been extremely active this year, erupting multiple times in several styles. Here, in this photo taken by Italian astronaut Luca Parmitano from the International Space Station…Etna smolders, sending ash and gas into the air.

A tropical snowflake

This photo was taken by and shared on the twitter feed of Italian astronaut Luca Parmitano while on board International Space Station.

It’s an overhead shot of a mountain near La Paz, Bolivia. The mountain sits within the tropics, but it’s tall enough for snowcaps and glaciers. The ice has formed a series of grooves and ridges along the slopes, creating an almost-symmetric pattern when viewed from above.

My eye calls it a snowflake; he compared it to a white poinsettia. Either way, a good show.
