Question
What exactly is a super nova, and could they be harmful?"

Answer
Hi Jasmine,

A supernova is, literally, a "brilliant new star", or, more precisely, an exploding star. And, yes, they can be very harmful. A more complete explanation is too lengthy for this - please see http://en.wikipedia.org/wiki/Supernova.
