Other Developments on Imagine the Universe!

We've re-organized the science articles into topic areas which we hope will be more useful to our users. Users may now better decide whether they want information about the basic concepts used in studying the high energy universe, information about the objects we study, the big outstanding questions we still have, or the tools we use to study this area of astronomy. We've also given the advanced treatments of these topics their own index page.

We've revised some of the science articles (pulsars, white dwarfs, and cataclysmic variables) to better fit this scheme, and will continue to do so in the months ahead.
