Some stars explode as supernovae when they run out of the hydrogen which they depend on to stay hot. Another way is due to binaries - when a particularly large star, e.g. a red giant, attracts a smaller star due to gravitational pull, and they orbit each other. The star cannot bear the heat and explodes in a massive amount of heat and light - that is how novae happen. A supernova has a much larger effect than a mere nova, and they happen when the star collapses due to reduction of fuel before the spontaneous explosion, and thus causing it to be much larger and brighter.
What else can I help you with?
Is a supernova massive?
A supernova can be massive but some aren't. Every supernova is a dieing star. Supernovae are exploding stars. They represent the very final stages of evolution for some stars. Supernovae, as celestial events, are huge releases of tremendous energy, as the star ceases to exist, with about 1020 times as much energy produced in the supernova explosion as our Sun releases every second.
What did people think of the first supernovae?
People in ancient times often associated the appearance of supernovae with various beliefs, omens, or religious significance. Some cultures saw them as signs of impending doom or the death of a king, while others interpreted them as new stars being born. They were sometimes recorded in historical texts and were occasionally perceived as celestial events of great importance.
How fast do supernovae travel?
Supernovae themselves are explosive events marking the death of massive stars, releasing energy and materials at incredible speeds. The shockwaves produced can travel at speeds of about 10,000 to 30,000 kilometers per second (approximately 22,000 to 67,000 miles per second). However, the ejected material from the supernova can expand at speeds of around 1,000 to 3,000 kilometers per second (about 2,200 to 6,700 miles per second). Overall, supernovae represent some of the most energetic and rapid phenomena in the universe.
Will all stars that become supernovae leave behind a neutron star?
Not all stars that undergo a supernova explosion will leave behind a neutron star. Depending on the mass of the star, the remnants could be a neutron star, a black hole, or in some cases, nothing at all if the explosion completely obliterates the star.
Can a planet go supernova?
No, only large stars go supernova when nuclear fusion breaks down. While white dwarfs can go supernova in some instances, brown dwarfs are failed stars which are not powered by nuclear fusion.
How do you know that some stars explode as supernovae?
How do we know? Because we can observe it happening.
Are dying stars bright?
Yes, dying stars can become very bright. As they run out of nuclear fuel, some stars expand into red giants or supergiants, which can increase their brightness. Additionally, some dying stars, like supernovae, can produce intense bursts of light as they explode.
Do the stars in the sky last forever?
No, stars have a life cycle. They form, go through various stages depending on size, and eventually cease to exist. Some may explode in supernovae, while others may become white dwarfs or black holes. Ultimately, all stars will eventually burn out and die.
What is it called when stars in the sky die?
Some stars explode in a supernova.
Do stars explode?
Some stars do. They can be nova or supernova stars, depending on the scale of the explosion.
How are the elements Li and Fe made?
Li (Lithium) is primarily formed in the Big Bang, with some additional amounts formed in supernovae explosions. Fe (Iron) is mainly produced in the core of massive stars through nuclear fusion reactions, and then released into space when these stars explode as supernovae. Both elements play crucial roles in the formation of planets and stars in the universe.
A dying giant star can suddenly explode becoming?
i dont understand your question but this might help when a star for example the sun its in its middle stages of life like in 10,000,000 years it will become a red giantand then become a white drawf or it become some other things but i dont think the stars wil actually blow up. hopefully this awnsers your question

Who are some European movie stars?
dont have a clue
Is the Philippines ready for different discoveries in astronomy?
Yes. With modest instruments, we can discover comets. Scanning the night sky with modest-sized telescopes might reveal a previously unknown asteroid. Supernovae might appear in some bright galaxies, or some of the red giant stars could explode as supernovae anytime soon. Prof. Christopher Go of Cebu City discovered the reddening of a storm system in Jupiter which soon was dubbed Red Spot Junior. We can contribute to the discovery of extrasolar planets. We can constantly monitor the planets and detect changes in their atmospheric systems.
What is the conclusion about stars?
Stars are massive celestial bodies that emit light and heat through nuclear reactions in their core. They are crucial for creating and dispersing elements essential for life and play a key role in maintaining the structure of galaxies. Stars come in various sizes, colors, and ages, with some eventually evolving into supernovae or black holes.
Why do some stars become red giants and others become supernova?
i dont know
