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. 2019 October 21 IFRAME: [2]https://www.youtube.com/embed/AhWMOkrzKzs?rel=0 A Mercury Transit Music Video from SDO Video Credit: [3]NASA's [4]Goddard Space Flight Center, [5]Genna Duberstein; Music: [6]Encompass by [7]Mark Petrie Explanation: What's that small black dot moving across the Sun? [8]Mercury. Possibly the clearest view of [9]Mercury crossing in front of the Sun in 2016 May was from Earth orbit. The [10]Solar Dynamics Observatory obtained an uninterrupted vista [11]recording it not only in optical light but also in bands of ultraviolet light. [12]Featured here is a composite movie of the crossing set to music. Although the event might prove [13]successful scientifically for better determining components of Mercury' ultra-thin atmosphere, the event surely proved [14]successful culturally by involving [15]people throughout the world in observing a rare astronomical phenomenon. [16]Many spectacular images of this [17]Mercury transit from around (and above) the globe were [18]proudly [19]displayed. The next [20]transit of Mercury will take place in [21]three weeks: on 2019 November 11.
