Conjunctions, occultations and other “stars of Bethlehem”
The Great Jupiter and Saturn Conjunction
In the 21st of December 2020, the planets Jupiter and Saturn will be so close in the night sky, they will appear to merge in a single “super-star”, and event not seen in over 400 years. To mark the event, on the previous day the Instituto de Astrofísica e Ciências do Espaço (IA) and the Porto Planetarium – Ciência Viva Center will host an online debate, with IA researchers, about these ephemerids and their scientific and historical importance.
