How are stars created?

Stars are not created by anyone or anything, they can form themselves, or they can be said: stars are born by a very strong influence of nature called gravity.

Stars always form in galaxies. In galaxies, there are many very porous clouds of gas and dust. These clouds are called nebulae .

Gravity creates dumps in these porous clouds - like raisins in cakes. When one of these lumps begins to become solid, firmer and harder, it is also when their density increases. Density denotes the level of a solid, solid and high adhesion.

The cores of these hard solid gases are also getting hotter and when a certain temperature (millions of degrees) is reached, something very special begins to happen within it. That is, the hydrogen atoms combine to form helium .

(You probably know that atoms are the tiny parts that make up everything. All the gas, dust in the universe and even we ourselves are made up of atoms. ).

When hydrogen atoms combine to form helium, the fusion reaction takes place and produces a lot of energy.

When hydrogen atoms combine to form helium, fusion occurs, or fusion . This process releases a lot of energy and this is when a star is born.

The life and death of a star

Like us, stars are born, live, then die.The lifetime of a star depends on its mass at birth. Bright stars, with small masses, live extremely long.

Our sun is also a star. So far, the sun has existed for about 4.5 billion years and is currently in the midst of its entire life span. In the next 5 billion years the sun will get bigger and bigger but then it will begin to wither and eventually die. Its nuclear power would be off and it would just remain there, cool down, like a lump of coal in an already burned kitchen.

A dust nebula that would later turn into a star living in the galaxy's spiral arms like this.

Stars heavier than our Sun make life much shorter. The heaviest stars only live about 1 million years, but their deaths are much more beautiful, far more beautiful than the silent, gradual death of stars like our sun. They leave with a giant explosion and scientists call this phenomenon supernovae .

We are made of star dust

Have you ever heard people say it 'we're born of dust' ? It is true! Inside a star, helium atoms combine to produce carbon, carbon being the source of the chemicals that make up our bodies and all life on Earth.

There are still a lot of things we don't fully understand about the mysterious lives of stars. But fortunately, we have huge telescopes and satellites in space to collect increasingly clearer pictures of stars.

2. The star's formation is about 300 times brighter than the Sun.
