Not quite: until Tycho's observations made
in 1572, any changing phenomena in the skies
were supposed to happen inside the atmosphere.
Case in point were comets, and Tycho in fact
showed that a comet which appeared in 1577 
was further away than the moon.
If you do a Google search for 'supernova' 
and 'Aristotle', you'll find quite a bit of
stuff about this on the web.
