For the first time in 800 years Christmas Star will be visible

On December 21, Irish stargazers could be in luck, as for the first time in 800 years a Christmas Star will be visible in the night sky.

This is the first time since 1226 that a Christmas Star will have been observable with the naked eye, although this occurs every 20 year.

Coincidentally the Christmas Star will make its appearance on the winter solstice, the shortest day of the year in the northern hemisphere. 

It also coincides with the peak of the Ursid meteor shower, marking a spectacular end to the astronomical calendar in 2020.

The Christmas Star is so-called as it is believed that this celestial event may have been the star of Bethlehem, which the Three Wise Men in the Bible story of Jesus Christ’s birth followed. On Monday, Dec 21, stargazers should look towards the waxing crescent moon, in the west 45 minutes after sunset.

Each night leading up until 21 December, Jupiter and Saturn will “gradually move closer to each other”, according to Nasa.

Though they may appear close they are hundreds of millions apart, says Nasa. It has also warned that one need to look fast as both planets will set shortly after sunset.
