¿ 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 December 30 IFRAME: [2]https://www.youtube.com/embed/aokGqxVdpz0?rel=0 Jupiter and Saturn Great Conjunction: The Movie Video Credit: [3]Thanakrit Santikunaporn ([4]National Astronomical Research Institute of Thailand); [5]Text: [6]Matipon Tangmatitham Explanation: Yes, but have you seen a movie of Jupiter and Saturn's Great Conjunction? The featured time-lapse video was composed from a series of images taken from [7]Thailand and shows the two giant planets as they angularly passed about a tenth of a degree from each other. The first [8]Great Conjunction sequence shows a relative close up over five days with moons and cloud bands easily visible, followed by a second video sequence, zoomed out, over 9 days. Even though [9]Jupiter and [10]Saturn appeared to pass unusually [11]close together on the sky on [12]December 21, 2020, in actuality they were still nearly a [13]billion kilometers apart. The two gas giants are destined for similar [14]meet ups every [15]19.86 years. However, they had not come [16]this close, angularly, for the past [17]397 years, and will not again for another [18]60 years. If you're [19]willing to wait until the year [20]7541, though, you can see Jupiter [21]pass directly in front of Saturn.
