On December 21, 2020, Jupiter and Saturn will be only 1/5 of a moon-diameter apart! Guy Ottewell offers insights and charts showing a magnified (telescopic) view of their once-in-20-years great conjunction.
Astronomer, artist and poet Guy Ottewell's beloved Astronomical Calendar ended its yearly print run in 2016, its 43rd year. It was continued as a web page for 2017 to 2021 [https://www.universalworkshop.com/astronomical-calendar-any-year/] and is now continued as a full online book for 2022 [https://www.universalworkshop.com/astronomical-calendar-2022/]. Visit Guy’s website UniversalWorkshop.com or his blog at UniversalWorkshop.com/Guysblog. You can also find times for over 600 astronomical events, such as planets’ oppositions and conjunctions, the moon’s phases, eclipses, equinoxes and solstices, meteor showers, and more at https://www.universalworkshop.com/astronomical-calendar-any-year.
