This summer holiday brought me to Tenerife, part of the Canary Islands, Spain. It's a popular destination because of the climate, but it's also the home of Teide, the world's second highest volcano (7500 m, measured from the sea floor). The incredible views reach way beyond earth, into outer space, the Milky Way and other distant galaxies.
Last week me and my wife went to Sicily for a little summer holiday. It is the largest island in the Mediterranean Sea. It is an autonomous region of Italy, along with surrounding minor islands. It's home to Europe's largest active volcano: Mount Etna. We had a chance to visit this lava spurring monstrosity and it was quite the experience.
