Northern Chile - elkins
Spent two days ascending 17,000 ft in the Chilean desert (on the border of Bolivia) to the second highest building in the world, which houses the world's most powerful supercomputer, recently built to make the oldest parts of the cosmos visible for the first time. This is the driest place on the entire planet...the lack of water vapor in the air allows the milky way to be so visible it can cast your shadow. I was grateful for the oxygen mask.
