How long does it take for a supernova to occur from beginning to end? (i.e., from the start of the explosion to the release of most of the star's material)
It has a very short time span for about 100 seconds. In essesence it takes roughly a few million years for the star to die, about less than a quarter of a second for its core to collapse, a few hours for the shockwave to reach the surface of the star, a few months to brighten, and then just few years to fade away.
What causes the remnant of the Supernova to dissolve into the interstellar medium? Why doesn't the explosion simply continue on until it hits planets or other masses in space?
supernovae releases heavy elements that make up our solar system including the earth. The X-Ray shows that heavier elements that are larger than normal, indicates that they are formed during the explosion. It doesn't continue because the remnants can cool off and fall which allows interstellar clouds to form new stars and planets.

DeleteThe first stage and last stage of supernova look very similar, how do you tell them apart?
ReplyDeleteWhat happens to left over supernova gases and particles?
ReplyDeleteWas the supernova observed by Kepler the only one do we have evidence of other supernovas since then?
ReplyDeleteHow did they discover the 7 supernovae that were discovered before the 17th century?
