That depends on how far away the star is. If the exploding star is 1,000 light years away we would see the supernova 1,000 years later. If it is 2,000 light years away we would see it 2,000 years later.
Either somebody shoots at the star. Or kills the star turning it into a supernova.
There is no star near mars.If there was, and it did explode, then you would not be alive to see it, let alone hear it.Sound cannot travel in a vacuum, so although you may see it, you would not hear it.
First of all, there is no reason for Jupiter to explode, and there's nothing about to cause it to explode. If for some reason Jupiter did explode, then the results would be very noticeable to observers on Earth. The most cataclysmic result would be that Jupiter would no longer be visible in the night sky. And as if that were not enough, every one of Jupiters 60 or more moons would cease its orbit around Jupiter, and would just continue orbiting the sun, in much the same but not exactly the same path as it does now.
Earth is a planet. A star would be much more immense and powerful; for example, the sun.
Fireworks are designed to explode in the sky, producing dazzling colors and shapes. If a firework were to somehow reach a star, it would be burned up long before getting close due to the intense heat and radiation emitted by stars. Stars are incredibly hot and massive celestial bodies, much larger and more powerful than fireworks.
There is no star called Orion. If there were, then it would depend on how fast you were going.
A planet cannot explode on it's own. A star would experience very little changes if a planet did explode, even one as large as Jupiter.
If a dwarf star crashed into a planet,the planet would likely explode.
Unless a planet is made from an explosive compoundor is shot with a nuclear bomb, then it is unlikly to explode in the first place.However, if the star exploded, then all the planets orbiting that star, would most likely be caught in the blast.
Easy answer: it would take 72 years.
How long will depend on the velocity. The closest star would be 4.24 light years away
It would take 100 Earth years for a signal to travel from a star located 100 light years away to reach Earth.
The Cobra star does not exist.
No. Only the most massive stars explode.
It would take 100 years for a signal to travel from Earth to a star located 100 light years away.
OK maybe when is runs out of gas all the gas around it will explode because the heat of the star too. so that is why the stars explode
The Sun is the Earth's closest star. Without the Sun there would be no light and no heat and life would not be able to exist on Earth.
