NGC 253 also goes by the
name of "Sculptor Galaxy"
after its parent constellation, or
by the name "Silver Dollar
Galaxy", presumably after its
visual appearance in the
eyepiece. NGC 253 is
classified as a starburst
galaxy, but interestingly, only
1 supernova has been found
within. It is a bright galaxy,
easily visible in binoculars,
and probably about 10 million
lightyears distant.
