Was the star of Bethlehem a real astronomical event?

[CoxRox]

I recently came across this web site:

http://www.bethlehemstar.net/

What if science can show, that the 'star' that was a sign of the Messiah's birth, did exist?

Here's a paragraph from the site:

THE STAR OF BETHLEHEM FASCINATES. For millennia, believers, scoffers and the curious have wondered at the Biblical account of the Star. The Bible recounts unusual, or even impossible astronomical events at Christ's birth. For many doubters, the account of the Star is easily dismissed as myth. For many believers, it's a mystery accepted on faith. But what happens if we combine current historical scholarship, astronomical fact and an open mind? Judge for yourself...

I'd very much appreciate any feedback.
