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. 2021 September 5 IFRAME: [2]https://www.youtube.com/embed/tvB0mdkrG3Q?rel=0 Earth and Moon Image Credit: [3]NASA, [4]JPL, [5]Galileo Project; Processing & License: [6]Gordan Ugarkovic Explanation: The Earth and Moon are rarely photographed together. One of most spectacular times this occurred was about 30 years ago when the Jupiter-bound [7]Galileo spacecraft zoomed past our home planetary system. Then, [8]robotic Galileo watched from about 15-times the [9]Earth-Moon separation as [10]our only natural satellite glided past our home world. The [11]featured video combines 52 historic [12]color-enhanced images. Although our Moon may [13]appear small next to the [14]Earth, no other planet in our Solar System has a [15]satellite [16]so [17]comparable [18]in [19]size [20]. The [21]Sun, far off to the right, illuminated about half of each sphere, and shows the spinning Earth's [22]white clouds, [23]blue oceans, and tan continents.
