Those red lines in the darkness on the left may seem little in this image from the International Space Station, but they aren't so tiny on Earth. That's Mount Etna, Europe's most active volcano as it's throwing a beautiful—and terrifying—fit. An active stratovolcano on Sicily's eastern coast, Etna has been putting on light shows like this for thousands of years. While most of her previous damage has been to property, not people, an eruption on March 16 injured 10 after magma and snow collided, spewing rocks into the air. Safe to say, she still doesn't have the power to reach the crew aboard the ISS, who are orbiting about 220 miles above Earth. ESA/NASA
