When Vulcan, the Roman god of fire, swings his blacksmith's hammer, the sky is lit on fire. A recent eruption of Chile's Villarrica volcano shows the delicate interplay between this fire -- actually glowing steam and ash from melted rock -- and the light from distant stars in our Milky Way galaxy and the Magellanic Clouds galaxies. In the featured timelapse video, the Earth rotates under the stars as Villarrica erupts. With about 1350 volcanoes, our planet Earth rivals Jupiter's moon Io as the most geologically active place in the Solar System. While both have magnificent beauty, the reasons for the existence of volcanoes on both worlds are different. Earth's volcanoes typically occur between slowly shifting outer shell plates, while Io's volcanoes are caused by gravitational flexing resulting from Jupiter's tidal gravitational pull.
