A CHRISTMAS STAR is set to appear in the skies above Ireland in just a few days.
Keep a watch out during the afternoon of December 21, because Jupiter and Saturn are set to align so that they appear to be one giant star.
And the fact that it's happening so close to Christmas means that to many, it'll resemble the Star of Bethlehem.
The last time this very rare astronomical occurrence was seen was over 800 years ago.
You'll be able to see the phenomenon with the naked eye, but if you've got a pair of binoculars or a telescope handy, you'll be able to zoom in and "watch the dance of Jupiter's four moons, Europa, Io, Callisto and Ganymede," according to Astronomy.com.
John Maclean, who is a member of the Royal Astronomical Society, said: "This conjunction has not happened since December 1623, although that one was not visible due to being so close to the Sun at the time.
"The last time a visible 'Great Conjunction' took place was in 1226, hence this year's event being the 'first' in 800 years," he added.
Experts believe the conjunction will happen around 1.30pm, but will be bright enough to see from all over the country.
