Cover Illustration: Two B-band images of the Phoenix
dwarf galaxy at
different epochs ( top), and the difference of the two using new
software to register and scale the images ( bottom left) and to
match their PSFs ( bottom right). In the fully matched case
about a dozen Cepheid variables are readily apparent, as is one high
proper-motion star just below and left of center. Figures provided by
Andrew Phillips and Lindsey Davis (see their paper
).
