Yes, in principle life can form on any suitable planet.


Stars in any form of galaxy are quite well separated except possible at the galactic centre. The only effect which can affect life is if a star goes supernova within about 10 light years. The radiation from the supernova could eradicate any life.

The requirements for life, as we know it, are a planet at the right distance from a main sequence star with the right combination of chemical compounds.

As long as the life bearing planet's star isn't within 10 light year of a star which could supernova, then life can flourish.
