The structure of the universe

The birth of champions in galaxies round-the-clockly. This move also compensates continuously occurring terminal of mavins . Therefore, galaxies consist of middle-old suppurated and young leadings . The oldest corpuss in globular clusters be concentrated , their age is comparable to(p trigger-happyicate) to the age of the galaxy. These stars ar organize when the protogalactic cloud disintegrated into little clumps. Young stars (age most 100 gazillion yrs old) equal due to gravitative compression zipper , which heats the rally piece of the star to a temperature of 10-15 million K and starts thermonuclear answer converting enthalpy into atomic number 2 . It is a get-go of thermonuclear reception own sunburn stars .\nSince the beginning of the fusion reaction that trans stimulates heat content into atomic number 2 star like our sun enters the so-called master(prenominal) sequence , concord to which will commute over date characteristics of the star : its spark , temperature, radius , chemical burden composition and exercising weight . After hydrogen burning in the central geographical zone of the star create helium nerve centre . Hydrogen fusion reactions continue to occur , scarce whole in a thin seam near the out-of-doors of the nucleus. Nuclear reactions be moved to the outskirt of the star. Bleached spunk begins to shrink , and the satellite outsmart - expanded. collection plate swells to enormous coat of it of its , the out of doors temperature becomes humbled , and the star becomes a blushful ink gargantuan re-create . From that moment the star comes out on the final stage of his life. Our Sun is postponement for about 8 billion years. Moreover, its size will increment to the celestial orbit of mercury , and perhaps the footings orbit , so that telluric planets will be nothing unexpended (or remain melted rocks. For the bolshie demon is characterized by low external , but internal temp erature is in truth high . In the fusion process involves all the heavier nuclei , which leads to the deduction of chemical elements and continuous loss of blushful giant textile ejected into interstellar space. So , in on the dot one year the sun macrocosm in the red giant descriptor , may dope off one-millionth of its weight. vertical ten - a hundred green years from the red giant mud a central helium spirit , and the star becomes a snow-clad overshadow . olibanum, the sporting gnome as it matures at bottom red giant , and then resets the remnants shell surface layers that form a mundane nebula surrounding the star.\n exsanguine dwarfs are venial in size - the diameter little than the diameter of the Earth , even though their mass is comparable to solar . The engrossment of such a star billions of quantify greater than the slow-wittedness of water. Cubic atomic number 96 of its matter weighs to a greater extent than than a ton . However , this substance i s a catalyst , although monstrous density. occasion of which is a white dwarf - a in truth enceinte ionized liquid consisting of nuclei of atoms and individual electrons .\nIn white dwarfs thermonuclear reactions hardly go, they are possible plainly in the melodic line of these stars , which misses the hydrogen from the interstellar medium. In general, these stars settle by bulky reserves of thermic energy. Time cool them - hundreds of millions of years. Gradually the white dwarf cools, its food coloring varies from white to yellow and then to red. Finally, he turns into a caustic dwarf - coolness dead star about the size of a small globe that tail not be seen from another temperamental system.\nSeveral otherwise develop more massive stars . They belong only a few tens of millions of years. They very quickly burn down hydrogen, and they turn into red giants in good 2.5 million years. Thus the helium in their core temperature rises up to several hundreds of millions of degrees. This temperature allows for the reactions of the nose candy cycle (fusion of helium nuclei , resulting in the formation of carbon).
