DezoitoFar from city lights, the Amazon rainforest reveals one of nature's most spectacular shows. Here, thousands of stars pierce the darkness with extraordinary clarity. The Milky Way stretches across the sky like a slithering serpent, a view that indigenous peoples have cherished for millennia.<br>

Linda Sgoluppi Artist<p>Truly dark sky (no artificial light at all) and a hooley of a gale through he night, my bedroom window open so it felt almost as if I were outside but I was cozy under the covers.
