Detailed explanation-1: -A supernova is the explosion of a star. It is the largest explosion that takes place in space. Where Do Supernovas Take Place? Supernovas are often seen in other galaxies. But supernovas are difficult to see in our own Milky Way galaxy because dust blocks our view.
Detailed explanation-2: -A star can go supernova in one of two ways: Type I supernova: star accumulates matter from a nearby neighbor until a runaway nuclear reaction ignites. Type II supernova: star runs out of nuclear fuel and collapses under its own gravity.
Detailed explanation-3: -Type Ia supernovae. • Their spectra show very little hydrogen and a lot of carbon; they also show silicon, calcium, and elements up to iron (due to fusion during the intense explosions). Type Ib supernovae. • Type Ic supernovae. • Type II supernovae. • 29-May-2012
