As one of the most arid places on Earth with less than ten millimetres of precipitation per year and humidity that often drops below 10%, the Atacama Desert gets over 300 clear nights every year — which is great for the European Southern Observatory. Surprisingly, while the desert is extremely dry, it gets snow for a couple of days every year. Stéphane Guisard took this picture: evidence that snow has dusted the desert landscape. Wow.
