Kawah Ijen Volcano, Indonesia
The country of Indonesia has some of the most spectacular, breathtaking natural beauty in the world. So it’s not surprising that the electric-blue water ejected from the Kawah Ijen Volcano made this list. Even though it looks like the starry sky of an alien planet, it’s found on Earth. The volcano emits sulfurous gases that ignite when they meet the Earth’s atmosphere, which is rich in oxygen. This creates a rich blue flame that illuminates the volcanic landscapes at night. During the daytime, it looks like any other volcano. If you’re a night owl, then this is the place for you (Geology).
