KOMPAS.com- Stars have a life and death cycle similar to Earth’s. At the end of his life, Dead star It explodes in the universe and is marked by events Supernova In the form of the brightest flash.
This one The secrets of the universe About celestial bodies, about the life and death cycle of a star.
At night, the twinkling stars are the rocks that decorate the dark night sky. Starlight emission is caused by atomic fusion reactions, which produce energy occurring at the center.
In astronomy, stars are celestial bodies made up of hydrogen and helium, which produce light and heat from rotating nuclear fusion in their centers.
Stars begin their lives when hydrogen fusion ignites in a hot, dense core. The gravitational pull of the star’s mass shrinks and becomes a tiny dot.

However, the energy released by fusion is pushed outward, creating a subtle balance that lasts for millions or trillions of years.
Dwarf stars are usually long-lived.
Then how How dead stars Or end his life?
In general, type Dwarf star Red alone will burn hydrogen at its core in trillions of years.
This is because as they age, these dwarf stars slowly fade away, turn into noble helium and hydrogen clusters, and then continue to shine throughout the universe.

When the biggest stars in the universe died and disappeared, things got even more violent.
As stars increase in size, nuclear fusion reactions occur more rapidly in order to maintain equilibrium with the force of gravity.
Massive stars have a much shorter lifespan than stars katai Red.
Massive stars are only a few million years old, then the stars die and then disappear.
When a star dies, the large number means that it has sufficient gravitational pressure to combine with hydrogen, helium, carbon, oxygen, magnesium, and silicon. The number of elements a giant star produces at the end of his life.

NASA’s Hubble Telescope Imaging, the light spectrum forms of NGC 6302, otherwise known as the Butterfly Nebula. Stellar nebulae that end their lives are called supernovae or stellar eruptions.
Once these stars form this iron core, that is the end of the star’s life journey.
All the elements that make up a giant star enter the iron core, but the fusion of iron does not release the force to fight it. On the other hand, the iron core shrinks to a solid, so that electrons are pushed into protons.
Then turn the entire nucleus into a giant neutron ball. The neutron ball can temporarily withstand a catastrophic inductive fall Supernova eruption.
This supernova event will release more energy in a week, which will release more energy than the sun, which has been emitting for 10 billion years.

When a supernova occurs Galaxy For us, the eruptions were as bright as day and brighter than the moon at night.
Supernova eruption It is a marker for a dead star, but when the spaceship is caught by the telescope this explosion will appear to shine beautifully in the universe.
The problem for these medium-sized stars, including stars like our Sun, is that when oxygen and carbon balls form at their centers, they don’t have enough mass to melt into something heavier.
They just stood there, warming up from day to day. The remaining stars react and swell, causing them to turn red and then to form red giants.
When our sun turns into a red giant, its edges almost reach Earth’s orbit.

This red giant lattice is unstable and stars like our Sun begin to blur, fall and float repeatedly, each event triggering the winds that carry the mass of the Sun into the solar system.
At its final death, a medium-sized star will eject its guts to form a bubble planetary nebula, a thin mass of gas and dust that surrounds its now exposed carbon and oxygen centers.
The embryo gets a new name when it is exposed to a vacuum that is identifiable by a white dwarf.
Had to White illuminates the surrounding stellar nebulae, tugging at it for about 10,000 years before the dead star’s body becomes too cold to allow such light to shine.
