Alto Atacama Hotel, San Pedro, Chile, South America, Planet Earth, Solar System, Milky Way. That would be the exact extra-terrestrial address for the hotel. The best part of the address is that all of it can be seen and enjoyed while you travel. You´ll get Chile from the air

When you travel to the desert you assume that the most you will see is earth, lovely colourful earth all around, this is why it is so exiting when you get the full satry view as the sun sets. In the dark and clear night skies of Atacama, you will enjoy as much as the naked eye can see of stars and milky way, and if there is anything you wish to view in more detail, go up to the hotel observatory, and enjoy the telescope!

We thought we´d help you look cool about the night, and share some Wikipedia information with you, about the Milky Way in particular:

The Milky Way, or simply the Galaxy, is the galaxy in which the Solar System is located. It is a barred spiral galaxy that is part of the Local Group of galaxies. It is one of billions of galaxies in the observable universe.

Its name is a translation of the Latin Via Lactea, in turn translated from the Greek Γαλαξίας (Galaxias), referring to the pale band of light formed by the galactic plane as seen from Earth (see etymology of galaxy). Some sources hold that, strictly speaking, the term Milky Way should refer exclusively to the band of light that the galaxy forms in the night sky, while the galaxy should receive the full name Milky Way Galaxy, or alternatively the Galaxy.[7][8][9] However, it is unclear how widespread this convention is, and the term Milky Way is routinely used in either context.
