No. A supernova is only a single exploding star and only the mass of one large star is involved. A galaxy is billions of times more massive than even the largest star.
Galaxy
Supernova clusters are regions within galaxies where multiple supernova explosions have occurred relatively close to each other in space and time. These clusters provide valuable insights into the life cycle of massive stars and the impact of supernova explosions on their surrounding environment. A well-known example is the Cygnus Loop in the constellation Cygnus, which is a supernova remnant created by a cluster of supernova explosions.
When galaxies "collide", the individual stars do not actually smash together; they're far enough apart that they mostly slip past each other.
Probably type la supernova
supernova
yes they can and if that happens the galaxy will be destroyes :)
A supernova will create the pulsar.See related question.
There are many types of nebula and they can form within any galaxy. Generally, the normal types of nebula - planetary and supernova remnants will occur in the younger galaxies, so at a push spiral galaxies.
Normally it is known as the supernova's progenitor star.
there is only 1 universe and their is billions of galaxies in it !
None. Galaxies on the other hand do contain planets
There are billions of galaxies in the Universe.
