The Bible calls the light that led the magi a star, but that’s what most people call every light in the sky except the sun and moon. There has been endless speculation trying to explain the nature of this light. Some say that it was the alignment of Jupiter and Saturn, which astronomers calculate happened around 7 B.C. Others say it was a comet, or a supernova, an exploding star. But I think the scriptural evidence refutes all of these natural explanations. They saw the star at times, and then it’s apparent they didn’t see it when they stopped in Jerusalem, and then they saw it again and were overjoyed. The language says the star moved ahead of them and then stopped over the house where Jesus was. This would preclude the possibility of it being an actual star. I believe this was simply a unique light God provided for this special occasion—and it wasn’t the first time God used a light as a guide.
