It isn't the Star of Bethlehem that has astronomers abuzz this month.
Scientists have their telescopes trained on a tiny, pumpkin-coloured dot in the Eastern night sky, a celestial body which - to the naked eye at least - now appears brighter than any star.
It isn't a star, however, but the planet Mars that is particularly close to the Earth right now - and won't appear this large again until 2016. A number of Bay Area observatories and astronomy groups have special viewings planned.

Directly overhead this month, just north of the brilliant Pleaides cluster in Taurus, is the constellation of Perseus named after the hero who slew the Gorgon and used the dreadful spectacle of its severed head to turn his enemies to stone. This region is filled with a wealth of interesting objects. Its brightest star is Mirfak, or Alpha Persei, a star 6,000 times brighter than the Sun and 620 light-years away.
The most famous star in this constellation, at a distance of 93 light-years, is Beta, better known as Algol, the Demon Star, so called because even in ancient times its largest companion was periodically seen to blot out its face, given it the appearance of a winking devil.
In the south of Perseus is Zeta Persei, or Atik, a very powerful star at least 16,000 times more powerful than the Sun, and well over 1,000 light-years away.
