Nova and Supernova explosions. Which happens depends on the type and size of the star.
A Nova explosion is a thermonuclear explosion occurring everywhere on the surface of an old star, in some situations multiple Nova explosions can happen over time on the same star if additional hydrogen is captured by the star.
A Supernova explosion happens only in very high mass stars that have completely consumed all the fusion fuels in their core (which now consists of a plasma of the elements nickle and iron) and the core thus burns out. Without the heat of fusion to support the outer portions of the stat, it collapses. The end result of the collapse is a "rebound explosion" that blows the star apart and leaves one of two types of stellar remnants, depending on the mass of the star: a neutron star (a compact object composed of only neutrons) or a blackhole (a deep gravitational well into which all the mass of the star disappeared).
What else can I help you with?
Possibly the most cataclysmic event associated with the death of a star is the?
For a star that is 10x or more the size of our sun? Supernova explosion, followed by the implosion of the star, forming a neutron star. For a star that is 50x or more the size of our sun? Supernova explosion followed by the implosion of the star, crushing down extremely small, forming a black hole. For a star that is 100x or more the size of our sun? Supernova explosion followed by the implosion of the star, crushing down extremely small, forming a supermassive black hole
What do you call an exploding sun?
A sun that explodes is called a supernova. This is a powerful and cataclysmic event where a star releases an immense amount of energy, leading to a bright explosion that can outshine entire galaxies for a brief period of time.
What constellation is the star of Bethlehem?
The Star of Bethlehem is traditionally associated with the Christmas star, which is thought to be an astronomical event rather than a specific star in a constellation. Some theories suggest it could have been a comet, supernova, or planetary alignment.
Massive stars terminate in a brilliant explosion?
Massive stars end their lifecycle in a cataclysmic event known as a supernova explosion, where the outer layers are ejected into space, leaving behind a dense core such as a neutron star or black hole. This explosion releases an immense amount of energy and synthesizes heavier elements that are dispersed into the universe.
When a star's core collapses a giant explosion happens called a?
When a star's core collapses, a giant explosion called a supernova occurs. This cataclysmic event marks the end of the star's life cycle and can outshine entire galaxies for a brief period. The explosion is often triggered by the gravitational collapse of the core after nuclear fusion ceases, leading to a dramatic release of energy and ejected material into space. Supernovae play a crucial role in distributing heavy elements throughout the universe.

For a star that is 10x or more the size of our sun? Supernova explosion, followed by the implosion of the star, forming a neutron star. For a star that is 50x or more the size of our sun?

Supernova explosion followed by the implosion of the star, crushing down extremely small, forming a supermassive black hole
A nova event occurs if what?
A nova event occurs if hydrogen accumulates onto the surface of the star, which ignites and starts nuclear fusion at a very fast rate. It's a cataclysmic nuclear explosion in a white dwarf. This causes an instantaneous lighting up of the star.
How old is a star?
A Supernova is not a particular star. A supernova is a cataclysmic event that occurs at the end of a high mass star life. They have been occurring for billions of years, and will continue to do so for billions more. Therefore it is not possible to put an age to it.
What effect will a nova have on a star?
It will destroy it in a cataclysmic explosion.
A variable star that undergoes a cataclysmic eruption?
A good example of a variable star that undergoes cataclysmic eruptions is a type of binary star system called a recurrent nova. These stars have a white dwarf that accretes material from a companion star until it reaches a critical mass, resulting in a thermonuclear explosion on the surface. This causes a sudden increase in brightness that can be detected from Earth.
What does death star mean in greek?
In Greek, "death star" can be translated as "αστέρας του θανάτου" (asteras tou thanatou). The term combines "αστέρας" (asteras), meaning "star," with "θάνατος" (thanatos), meaning "death." It is not a commonly used phrase in Greek and may evoke imagery associated with destruction or danger, particularly in a science fiction context, such as the iconic Death Star from the Star Wars franchise.
What do you call the death of a star?
The death of a star is called a supernova or stellar explosion. This is a catastrophic event that occurs when a star reaches the end of its life cycle and can result in the star either collapsing into a dense core (neutron star or black hole) or completely exploding.
What gas is most likely to make up the star of bethleham?
The "Star of Bethlehem" mentioned in the Bible is believed to be a conjunction of planets rather than a single star. There is no specific gas composition associated with it. The bright light associated with the "Star of Bethlehem" could have been a natural astronomical event.
What do you call an exploding sun?
A sun that explodes is called a supernova. This is a powerful and cataclysmic event where a star releases an immense amount of energy, leading to a bright explosion that can outshine entire galaxies for a brief period of time.
What is a death star?
The death star is known as the nemesis star AKA the death star, brown dwarf star, red dwarf star, or the sun's twin.
Is the Death Star a star?
No, the Death Star is not a star. It is a man/droid made space station.
What happens during the life of the sun from birth to death?
From When a star is formed in the nebulae ( Mass amounts of chemical gases , stretching millions of miles ) a star will naturally burn up the neclear energy. However, major influences on how long a particular star live for can depend on a vast amount of aspects. A major one being the size and weight of any given star. For Example in our solar system, the sun is rather young compared to many other throughout the galaxies. ( It was formed about 4,500,000,000 (four and a half billion) years ago and we expect it to carry on pretty much as it is now for a few billion years yet - so no surprises in our life times )In Death cataclysmic events that herald the end of a star's life determin what faite a star shall have. Whether shrinking to become a white dwarf or imploding to form a black hole, the death of a star is a dramatic spectacle, that various scientist revel to spectate. This unique event happens frequently as there are many stars in the universe. However seeing them can be difficult.
