super nova
my opinion:
A super nova It is the result of an exploding star, especially on that has possibly collapsed and then exploded because it got to too high
a pressure. It is now believed that the heavier elements are created in the pressures of an exploding supernova, that is ,this is thought to be the only place this happens.
Here is a little definition on a supernova
The explosion caused when a massive star, at least 8 times the Sun's mass, dies (exhausts its fuel) and collapses. If the original star is less than 20 solar masses, the supernova will leave behind a neutron star. Heavier stars will collapse into black holes.
There are several different kinds of supernovae, which are believed to be caused by two distinct sources. One possible cause for Supernova occurrences results from a star halting its generation of fusion energy from fusing the nuclei of atoms in its core, causing it to collapse under the force of its own gravity. Another possible source occurs when a white dwarf star accumulates material from another nearby star until it nears its Chandrasekhar limit and undergoes runaway nuclear fusion in its interior, ultimately leading to its destruction.
One of the most energetic explosive events known is a supernova. These occur at the end of a star's lifetime, when its nuclear fuel is exhausted and it is no longer supported by the release of nuclear energy. If the star is particularly massive, then its core will collapse and in so doing will release a huge amount of energy. This will cause a blast wave that ejects the star's envelope into interstellar space. The result of the collapse may be, in some cases, a rapidly rotating neutron star that can be observed many years later as a radio pulsar.

when does a super nova occur?
On average, supernovae occur about once every 50 years in a galaxy the size of the Milky way and play a significant role in enriching the interstellar medium with heavy elements.Furthermore, the expanding shock waves from supernova explosions can trigger the formation of new stars.
super nova are normally are classify according to the lines of different chemicals elements that appear in their specta Supernova remnants are the dramatic objects produced by the violent explosion of a massive star at the end of its life. This explosion, called a supernova , is one of the most energetic events in the universe, and causes a single star to briefly outshine the entire galaxy in which it is located. Supernovas in our own galaxy have produced spectacular light shows in the night (and often in the daytime) sky, but the last supernova in the Milky Way galaxy that was visible from Earth was in 1604.
