Astrophysics in 1999

Abstract

The year 1999 saw the arrival of a star with three planets, a universe with three parameters, and a solar corona that could be heated at least three ways. In addition, there were at least three papers on every question that has ever been asked in astrophysics, from ``Will the Universe expand forever?'' to ``Does mantle convection occur in one or two layers?'' The answers generally were, ``Yes,'' ``No,'' and ``None of the above,'' to each of the questions. The authors have done their best to organize the richness around centers defined by objects, methods, and madnesses.
