One of the many faces of Uluru is displayed to us just after the sun has set on a late spring evening. The rising full moon climbs into the intense blue of Blue Hour, the rock changing shade with every passing minute. In the twilight, the light of the full moon bathes the rock and foreground, intensifying the orange and red of Uluru's "Twilight's Aura". Uluru (Ayers Rock) is a sandstone monolith located in the Uluru Kata-Tjuta National Park in Australia's Northern Territory.
