The Planetary Conjunction between Jupiter and Saturn

The planetary conjunction between Jupiter and Saturn on December 21st, 2020.

Known as the Star of Bethlehem, in the popular belives, but is impossible since at the time of the Christ's birth, both planets were in opposition, this alignment event at the naked eye looks a very bright star in the nothern sky, and usually hapens from 800 years to 800 years.

In this capture it was also possible to see the Jovian Moons on Jupiter, and also Tetis (faintly) on Saturn. At the time, I had the opportunity to catch a fifth celestial object, who was later confirmed by the Dr. Brian Skiff from the Lowell Observatory, the Dr. Nelson Nunes from the Alqueva Observatory and a social media friend (Valter Reis), who they identified the object as the Star HD191250 - HIP99314.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
