Supernova Explosion facts
While investigating facts about Supernova Explosion 2022 and Supernova Explosion 2020, I found out little known, but curios details like:
In 1054, Chinese astronomers noted a bright "guest star" in Taurus that was visible in the daytime for 3 weeks, and didn't completely fade out for almost two years. The "guest star" was actually the supernova explosion that created the Crab Nebula, which is located some 6,500 light-years away.
how supernova explosion occurs?
In 1054 a supernova in the Constellation Taurus was observed that was bright enough to remain visible during daylight for perhaps as long as 23 days. The remnant of the supernova, which consists of debris ejected during the explosion, is now known as the Crab Nebula.
What elements are made through supernova explosions?
In my opinion, it is useful to put together a list of the most interesting details from trusted sources that I've come across answering what is the immovable object in a supernova explosion. Here are 16 of the best facts about Supernova Explosion Definition and Supernova Explosion Video I managed to collect.
what is supernova explosion?
-
A super massive star called Eta Carinae (7,500 light years from Earth) is nearing the end of its life. It could explode tomorrow or 1000 years from now in what is known as a supernova. The explosion will create a blast so violent that its flash will briefly outshine the entire Milky Way.
-
Once Iron begins to form in the heart of a giant star it only has seconds to live before it explodes into a supernova and most of the heavier elements such as Gold and Silver are formed in the resulting explosion.
-
In 2004, a Magnetar (a type of a Neutron Star with a powerful magnetic field) had a large gamma ray burst which briefly expanded the ionosphere. It is thought to be the largest explosion observed in the galaxy by humans since the supernova observed by Johannes Kepler in 1604.
-
When a supernova occurs the explosion results in the formation of elements such as gold and uranium. This is due to the extremely high temperatures (in the millions of degrees).
-
When a star dies it experiences an explosion called a supernova.
-
The average 70 kg (150 lb) adult human body contains approximately 7×10^27 atoms and contains at least detectable traces of 60 chemical elements, some of which are metals that were formed during massive explosions like Supernova.
-
A neutron star (the result of a supernova explosion of a massive star) is so dense that a matchbox filled with its material would have a mass of approximately 3 billion metric tons
-
Stars (some of them) may collapse into black hole directly without supernova explosion
-
All the Gold on Earth Comes From Massive Space Explosions Like Supernova and Hypernova!

Why can supernova explosions be heard on earth?
You can easily fact check why can't we hear supernova explosions by examining the linked well-known sources.
The element iron means star murder: all elements lighter than iron produce energy when fused, but iron absorbs energy instead, so when enough iron accumulates in the star core the sustaining pressure of nuclear reactions drops quickly and the violent contraction leads to a supernova explosion.

About failed supernovae. That sometimes when a star dies the energy just isn't enough to reverse the collapse into an explosion, and the giant star just instantly "dissapear" and turn into a black hole. - source
