KOMPAS.com- Stars also have a cycle of life and death like living things on Earth. At the end of his life, dead star in the universe will explode and be marked by events supernova in the form of a very bright flash of light.
This is one the secrets of the universe about celestial objects, about the life and death cycle of a star.
At night, the twinkling stars are gems that decorate the dark night sky. The emission of starlight is caused by a nuclear fusion reaction that produces energy that occurs at the core.
In astronomy, stars are celestial bodies formed from hydrogen and helium that produce light and heat from nuclear fusion rotating within their cores.
Stars begin their lives when hydrogen fusion ignites in a hot, dense core. The gravitational pull of the star’s mass compresses it and becomes a tiny dot.

However, the energy released by fusion pushes outward and creates a subtle balance that can last for millions or even trillions of years.
Dwarf stars will usually live for a very long time.
Then, how the way a star dies or end his life?
In general, type dwarf star red by itself will burn the hydrogen in its core over trillions of years.
Because, as they get older, these dwarf stars will continue to get brighter until they slowly fade, become inert helium and hydrogen clumps, then just roam the universe.

When the massive stars in this universe die and disappear, things will get even more violent.
Due to the increasing volume of stars, nuclear fusion reactions will occur faster to maintain equilibrium with gravity.
Massive stars tend to have a much shorter life span than stars katai red.
Massive stars are only about a few million years old, then the stars die and then disappear.
When a star dies, its large size means that there is sufficient gravitational pressure to combine hydrogen, helium, carbon, oxygen, magnesium and silicon. A number of elements produced by giant stars towards the end of their lives.

Once these stars form this iron core, that is the end of the star’s life journey.
All the elements that a giant star produces will enter the iron core, but fusion of iron does not release the energy to fight it. On the other hand, the iron nucleus will contract until it is denser, so that the electrons are pushed into the protons.
Then turn the entire nucleus into a giant ball of neutrons. The neutron ball will temporarily be able to withstand a devastating, triggering collapse supernova explosion.
This supernova event will release more energy in a week, more energy released than the sun released during its entire lifetime of 10 billion years.

When a supernova occurs in galaxy us, then the explosion is bright enough to appear during the day and can even be brighter than the full moon at night.
Supernova explosion is a marker of a dead star, although this explosion when captured by the space telescope will appear to be sparkling beautifully in the universe.
For these medium stars, which include stars like our sun, the problem is that when oxygen and carbon balls form in the core, they don’t have enough mass around them to melt into something heavier.
They just stand still and are getting hotter by the day. The rest of the stars react and swell so that they turn red and then produce a red giant.
When our sun turns into a red giant, its edges will almost reach Earth’s orbit.

This red giant phase is unstable and stars like our sun will convulse, collapse, and float over and over again, with each event launching a wind that carries most of the sun’s mass into the solar system.
During its final death, a medium-sized star will spew out its guts to form a bubbling planetary nebula, a thin mass of gas and dust that surrounds the now-open carbon and oxygen core in its center.
The nucleus received a new name when it was exposed to a vacuum that could be identified with a white dwarf.
Katai white illuminates the surrounding planetary nebulae, energizing it for about 10,000 years before the dead star carcasses become too cold to allow such a light show.
