Can something 73 million light years away be useful to astronomers? In
the case of NGC 1255, shown here, the answer is decidely yes. NGC 1255 is
a compact galaxy with lots of star formation taking place. The relationship
between its arms and the barred nucleus hint at what processes might
unfold in galactic evolution. For example, this galaxy (like many others)
displays spiral arm "rows" and other linear features. Astronomers would
like to learn whether these are transient features, long lived structures,
or perhaps even the result of interacting (nearby) galaxies.
