It's gamma rays will have traveled one light year.
A supernova is the catastrophic death of a star, characterized by a massive output of energy.
we all die
It is yes
If it's a big enough explosion it will become a supernova
A supernova occurs.
A supernova occurs.
Mass decides a stars ultimate fate.
Nebula. Some nebulae are formed as the result of supernova explosions. The material thrown off from the supernova explosion is ionized by the supernova remnant. One of the best examples of this is the Crab Nebula, in Taurus. It is the result of a recorded supernova, SN 1054, in the year 1054 and at the centre of the nebula is a neutron star, created during the explosion.
big explosion :O the sun is too small a star for a supernova.
A supernova happens when most of the core of the collapsing star has become neutrons, held up against gravity by neutron degeneracy pressure. At this point a shockwave reflects from the neutron star surface, driving the supernova explosion.So the answer to your question is neutrons.
The name is formed from SN (yes SuperNova), the year of discovery, then followed by a one or two letter designation. SN is optional.The first 26 of the year get designated with an upper case letter from A to Z. then, pairs of lowercase letters are used, starting with aa, ab.... etcetera Historical supernovae were known simply by the year they occurred: SN185, SN1572 SN1604. Since 1885, the letter notation was used.
The heavy elements are formed when a supernova explodes. That happens quite frequently, when a star suddenly increases in brightness by a huge amount for a few months. If a supernova is close to us it can be seen as a new star, and that happens about twice in 1000 years.
