The Stars Of The Night

Hello #BLURT Family. How are you all?

All the objects in space that can cause fusion reactions by igniting the matter inside them and the light is bright are called stars. They also refer to the brightest and largest spherical objects in the plasma state in space. At high temperatures they continuously generate their own fuel through the reaction of nuclear fusion. The heat and pressure generated by nuclear fusion prevents gravitational contraction. When the fuel runs out, a star dies and a white dwarf or neutron star is formed again into a black hole. The closest star to Earth is the Sun. The reason they shine is because the energy generated by the nuclear fusion reaction at its center travels through the entire interior of the star and radiates from the outer surface. Almost all elements heavier than hydrogen and helium were produced for the first time in the center of a star.

Astronomers can tell by observing the star's spectrum, luminosity, or motion, its mass, age, chemical composition, and many other religions. The total mass of the star determines its evolution and final outcome. Other religions are determined by evolutionary history, including diameter, rotation, pressure, and temperature. The image obtained by placing the temperature of many stars in a graph opposite their illuminating power is called the Heartsprung-Russell image. The current stage of star evolution and its age can be determined through this image.

The star's life cycle begins with a collapsing cloud. These clouds contain mainly hydrogen, although there may be very few rare heavy elements, including helium. When the center of the star is dense enough, the hydrogen in that center begins to turn into helium through a nuclear fusion reaction. The energy from the inner remnants of the star is carried out in a mixed process of radiation and convection.

These processes prevent stars from collapsing and the energy generated creates a stellar wind that scatters radiation throughout the universe. He died when he ran out of hydrogen fuel between the stars. Death occurs through various processes depending on the mass. However, before death, the star passed a few more generations, including the state of infertility. Each generation contains more heavy elements than its predecessor. They can be lonely, again two or more they can form a system together. The two usually revolve around each other and getting closer to each other also affects each other's evolution.
