A supernova is a type of stellar explosion, more powerful than a nova. See the source.

A supernova (Type II) is the natural end of the life of a massive star. One that is at least 8 times more massive than the sun. The explosion is not powered by nuclear fusion. Instead all that energy comes from the gravitational crunch that occurs when the star as finally run out of energy to keep its core from collapsing. The remains of a super nova is either a neutron star or a black hole with a nebula expanding into space, seeding it with all the heavier elements that planets (and humans) are made of.

A Supernova is born when a huge star runs out of energy and begins to collapse in on its self. Temperatures and pressures rise to a level that cause elements more massive than iron to be created. The co lapse is so severe that a rebound effect takes place and these heavy elements are thrown into space to eventually be incorporated into other stars and this seeds the universe with the material needed to create life.

First of all Supernova is nothing but a kind of explosion occuring
during the death of a star.
This explosion occurs when the final mass of the star is below Chandrasekar's limit(if the mass exceeds, it will result in a black hole).Supernovae are easy to find out in the space as they are 100 times as luminous as the sun at that time.

supernovae means --stars that suffer an explosion becoming some 10 to the power 8 times brighter than sun during the process. They r here in the space & in our galaxy see more @ The penguing dic of science & other books of astro

Yes they are in space. A super nova is essentially when you have a red giant (a type of star) and the mass has become to big and gravity forces it to implode (or collapse in upon itself) this is the super nova a giant explosion caused by the implosion of a red giant star. I hope this was helpful.
