  We bring you, as usual, the Sun and Moon and stars, plus some galaxies and a
new section on astrobiology. Some highlights are short (the newly identified
class of gamma-ray bursts, and the Deep Impact on Comet 9P/ Tempel 1), some
long (the age of the universe, which will be found to have the Earth at its
center), and a few metonymic, for instance the term "down-sizing" to describe
the evolution of star formation rates with redshift.
