Explanation: Stars come out as evening twilight fades in this serene skyscape following the Persian proverb “Night hides the world, but reveals a universe.” In the scene from last November, the Sun is setting over northern Kenya and the night will soon hide the shores of Lake Turkana, home to many Nile crocodiles . That region is also known as the cradle of humankind for its abundance of hominid fossils . A brilliant Venus, then the world's evening star , dominates the starry night above. But also revealed are faint stars, cosmic dust clouds, and glowing nebulae along the graceful arc of our own Milky Way galaxy .
