These out-of-this-world photos will make you feel like you're on another planet. Why spend years training to be an astronaut when you explore strange new worlds right here on earth? So what if you didn't pass the last phase of the Mars One screening process!

Sometimes, there might be exotic locations right under your nose - we often get bored of our own surroundings even though they might seem completely exotic or even surreal from someone who lives across the globe from you.

These alien photos span practically every continent on Earth, so you can experience fantastic sites like these no matter where you live. But one continent is missing from the list. Which one is it?
