Commemorative videos of the anticipated “Christmas Star” were captured around the world on Sunday and Monday.
The astronomical phenomenon was called the “Great Connection” after it was first observed in 1623.
This year, the spatial alignment will appear in the night sky for several days.
In the videos from the US, India, Pakistan and Ireland, a glowing white circle, Jupiter, can be seen in the night sky, in a close relationship with Saturn, a flat, orange disc shape.
This is the first time in nearly 400 years that Jupiter and Saturn have come so close to each other, according to NASA.
However, Jupiter and Saturn regularly pass each other and arrange once every 20 years, almost 800 years since the night was arranged, allowing everyone around the world to observe the event.

“Jupiter and Saturn will only be about 10 degrees in the sky, which is so close that if you stretch to the length of your pink arm, you will be able to cover both planets very easily with your pink color,” said NASA astronomer Henry Thrupe.
The planets will be visible to the naked eye when directed southwest after sunset, according to NASA. On Monday, they will appear so close that a pink finger at arm’s length will cover both planets in the sky, NASA said.
Like the winter solstice on the evening of December 21st, stargazers can see the “Christmas star” at a time when one of the Earth’s poles is at its maximum tilt away from the sun.
