Chris Hadfield, quite possibly my favorite current astronaut has snapped a spectacular photo of Italy’s Mount Etna volcano streaming ash toward the sea early this morning.
Mount Etna is the tallest active volcano in Europe, and in an almost constant state of activity, regularly spewing gas, ash, and lava from the four craters at its summit. Eruptions of Etna follow a variety of patterns. Most occur at the summit, but others can erupt on flanks just as well.
Mount Etna’s current eruption started with a stunning dawn lava fountain a week ago, followed by short, violent bursts, with lava fountains 800 meters high shooting out of the Bocca Nuova crater overnight.
Hadfield, an astronaut for the Canadian Space Agency, is aboard the International Space Station. He regularly posts stunning pictures on his twitter account, which I really recommend subscribing to. Kevin Ford, also astronaut on the ISS also took some great pics.
Andrei's background is in geophysics, and he published his first scientific paper when he was still an undergrad; now, his main focus is on how geology and geophysics can be applied to understand and protect the environment. Feeling that there is a gap between scientists and the general audience, he started ZME Science - and the results are what you see today.
