Astronomical Explanations of the Christmas Star
One of the astrnomical explanations of the Christmas Star is that it was a nova or supernova outburst: a original star blazes forth where none had ever been seen and leaves no trace for us to find in the future.
Although their names connote a new creation, these spectacular objects are in reality dying stars, although they are newfound (albeit temporary) additions to the nighttime sky. The appearance of a nova is intermittent a really bright one becomes ready perhaps once every 25 or 30 years.
Going on this idea, we actually should be due for a bright naked-eye nova at about anytime now, since the most recent one came out back in 1975 (not far from the brilliant star Deneb in the constellation Cygnus).
Most bright novae suddenly and unexpectedly flare into prominence literally overnight, arresting the instant attention of sky-conscious people. But after many days or weeks of such radiance, it gradually retreats back to obscurity. Even more astounding but much less common are supernovae; stars that suddenly expand themselves completely apart, briefly producing an astounding energy output equivalent to the combined light of an entire galaxy of stars.
At the pinnacle of its outburst, a supernova can glisten with a brilliance capable of casting shadows and can even be seen in broad daylight truly a ethereal announcement worthy of the birth of a king.
In our Milky Way galaxy, the foregone thousand years, there have been four radiant supernovae, in 1006, 1054, 1572 and 1604. Clearly, we are long in the tooth for another, though the stars don’t necessarily play by any odds we might count on.
A early possibility submits that the star of Bethlehem was a supernova or hypernova happening in the nearby Andromeda Galaxy. Although supernovae have been detected in Andromeda, it is remarkably difficult to detect a supernova remnant in another galaxy, let alone get an true date of when it happened.
Although a nova or supernova is the most passable hypothesis for the Star, there is a big problem with it, in that there doesn’t seem to be any definitive record of a bright nova coming out in the sky during the time that biblical historians consider the Magi made their journey.
