在智利阿塔卡马沙漠，天文导游正将极致星空转化为科学体验
In northern Chile, the Atacama Desert stretches over 100,000 square kilometers of the driest non-polar land on Earth. Here, at altitudes above 2,400 meters, the air is thin and bone-dry — and practically free of light pollution. This unique combination has turned Atacama into a global hub for astronomy, attracting both professional observatories and curious travelers who come solely to see the stars.
Yet a telescope alone does not make a meaningful night. At the heart of this astro-tourism boom is a small but passionate group of local guides, many of them former miners or teachers from nearby towns like San Pedro de Atacama. They have learned to read the southern sky as fluently as a map, pointing out constellations like the Southern Cross and the Magellanic Clouds, while explaining the physics of light-years and supernova remnants in simple, vivid terms.
