Not too sure a supernova can be popular.
The most beautiful should be SN 1604 or Kepler's Supernova.
The most popular WILL be Betelgeuse when we eventually see it.
Mass. E=MC2 Supernova explosions happen with the most massive of stars > 20 of our Suns.

There have been several recorded supernovae in the Milky Way. The earliest recorded Milky Way supernova was SN 185 (seen, as the name implies, in 185 C.E.), and the most recent supernova recorded was SN 1604 (seen in 1604 C.E.), or Kepler's Supernova.
A supernova is not a single star, but an event that occurs to the most massive stars when they reach the end of their life. Therefore it cannot be named. See related questions for details on Supernova
The universes most acurate time clock, a pulsar.
Most book stores have them in stock.
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.
There is no way of knowing which star will next go "supernova".However, closer to home, Betelgeuse is the most likely to produce a supernova - within humanities lifetime.
there is Hydrogen, Iron, Helium, Uranium and most of the elements. up to the 26th element
The Vela Supernova is the remnant of a supernova explosion that occurred in the Vela constellation about 11,000 to 12,300 years ago. It is located about 800 light-years away from Earth and is one of the closest known supernova remnants to us.
the most powerful weapon is the supernova lvl 99. that is the mega version of the harbinger
