¿ Astronomy Picture of the Day [1]Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2020 July 1 IFRAME: [2]https://www.youtube.com/embed/re3oEKX6Fks?rel=0 Our Rotating Earth Video Credit & Copyright: [3]Bartosz [4]Wojczynski Explanation: Has your world ever turned upside-down? It would happen every day if you stay fixed to the stars. Most time-lapse videos of the night sky show the [5]stars and sky moving above a steady Earth. Here, however, the camera has been forced to rotate so that the [6]stars remain fixed, and the Earth rotates around them. [7]The movie, with each hour is compressed to a second, dramatically demonstrates the daily rotation of the Earth, called [8]diurnal motion. [9]The video begins by showing an open field in [10]Namibia, [11]Africa, on a clear day, last year. Shadows shift as the [12]Earth turns, the [13]shadow of the Earth rises into the sky, the [14]Belt of Venus momentarily appears, and then day turns into night. The majestic band of our [15]Milky Way Galaxy stretches across the night sky, while sunlight-reflecting, Earth-orbiting [16]satellites zoom by. In the night sky, you can even spot the [17]Large and Small Magellanic Clouds. The video shows a sky visible from Earth's [18]Southern Hemisphere, but a similar video could be made for every middle latitude on [19]our blue planet.
