A ‘Christmas Star’ Will Appear on the Darkest Day of This Year

This Christmas there will be an astronomical phenomenon that has not occurred for the past 800 years. On Dec. 21, Jupiter and Saturn will come into such close alignment that they will appear to be a unit, calling to mind the “Christmas star” the Magi followed to find the newborn Messiah.

“Alignments between these two planets are rather rare, occurring once every 20 years or so,” Patrick Hartigan, astronomer at Rice University, told Forbes, “but this conjunction is exceptionally rare because of how close the planets will appear to be to one another. You’d have to go all the way back to just before dawn on March 4, 1226, to see a closer alignment between these objects visible in the night sky.”

When celestial bodies pass or appear to meet in the sky, astronomers call the event a “conjunction.” Even though Jupiter and Saturn experience a conjunction once every 19.6 years, they will not come into this close of an alignment again until March 15, 2080.

 

A Christmas Star on the Darkest Day of the Year

The day the “Christmas star” will appear happens to be the Northern Hemisphere’s winter solstice, which is the day of the year when the North Pole is tilted the furthest away from the sun. This is also the shortest and darkest day of the year for those living in this hemisphere.

The conjunction of the two planets will be visible to the naked eye everywhere on Earth, assuming local weather does not obscure it. People should look for the “Christmas star” in the southwestern part of the sky near the horizon for about an hour after sunset. That is when it will be brightest, although the conjunction might be visible at other times that week. Those viewing the phenomenon through telescopes will be able to see each of the two planets, as well as some of their moons.

What Was the Christmas Star, Actually?

Some have argued that the Christmas star, commonly called “the star of Bethlehem,” was in fact an alignment of Jupiter and Saturn or some other combination of planets. According to Britannica, German astronomer Johannes Kepler believed the Christmas star “may have been a nova occurring in or near some conjunction of bright planets.” Other views include that the Christmas star was a supernova, Jupiter by itself, or a comet.

Biblical scholar Dr. Colin Nicholl thinks there is compelling evidence that the star the Magi saw was either a large comet (like Hale-Bopp) or a supernova. One reason for believing it was a comet is that we know the star appeared suddenly and remained in the sky for one year. Other reasons include the nature of the star’s travel and the fact that it both rose in the sky and “stood over” the place where Jesus was born.

Some might question why it matters whether or not we can scientifically explain what the star of Bethlehem actually was, but Collins believes there is a benefit to doing so as an apologetic for the credibility of the Bible. Showing that the biblical account corresponds with our scientific knowledge demonstrates that the Bible and science are not opposed to each other. “This all constitutes powerful evidence that Matthew was a historically reliable biographer,” said Collins. “It also strongly supports the Gospel writer’s claim that Jesus is the Messiah prophesied in the Hebrew Scriptures.”

But even if the actual Christmas star was a comet rather than a conjunction of planets, this year’s astronomical event is a reminder on the darkest day of the year that, as Isaiah prophesied, “The people walking in darkness have seen a great light; on those living in the land of deep darkness a light has dawned.”
