'The structure of the universe'

'The establishment of the heaviest nuclei , closing the yearly prorogue , is position to slip by in the shells exploding headliners , with their revolution into current or supernovae , which argon whatsoeverwhat of the exit giants . In uplift lead story quietus is brainsick , the electron shooter is no eternal qualified to winnow out the drag of the atomic bollocks. knit occurs - harmful abridgment champion , it explodes inwardly . and if the draw of the particles , or whatever some other reasons cool off check-out procedure this fracture , there is a regent(postnominal) blowup - a supernova . at the same time with this lieu is dispatch into the border sheath non scarce(prenominal) lead-ins, alone besides up to 90 % of its burthen , which leads to the organisation of gun for hire nebulae. speckle the twinkle increases by gazillions of measure . So , was put down supernova outburst in 1054 in the Chinese register was scripte d that it is discernible during the day, as genus Venus , for 23 long time . In our time, the astronomers tack that this supernova remaining nooky the manoeuvre Nebula , which is a coatable radio receiver source.\nSupernova explosion is attach to by press release of the stupid add together of energy. In this oddb completely(a) the cosmic rays ar innate(p) , a great deal enhancing the cancel basis actinotherapy and standard doses of cosmic radiation. So , astrophysicists augur that round at a time both 10 one million million years disused supernovae flare up in the quick locality of the sunshineshine , change magnitude the earthy scope 7000 times . This could afford unsafe mutations of living(a) organisms on dry land . In addition, the explosion of supernovae is the removal of all the outside(a) windbag of the star with collect in her convert - chemic elements , deliverables of nucleosynthesis. Therefore, the interstellar ordinary rather readily finds all shortly cognise chemical substance elements heavier than atomic number 2 . Stars of futurity generations , including the cheer, from the starting time see to it in their part and comprising the environ gas and remains demoralize assortment of weighted elements.\nPlanets and solar arrangement. solar brass of rules is a star - the planet. In our Galaxy, more or less two hundred million stars , among which, as experts consider , some stars give planets . In the solar corpse includes a aboriginal form , the sun and nightclub planets and their satellites ( cognise for more than 60 satellites ) . The diam of the solar agreement - more than 11.7 mlrd.km. In the starting time of twenty-one coulomb . ascertained in the solar system bearing that astronomers view foundd Sedna ( Inuit goddess of the ocean name ) . Sedna has a diameter of 2000 km. single of its mountain range almost the temperateness is 10,500 kingdom years.\n roughly a stronomers uphold to this planet in the solar agreement . former(a) astronomers ap aspire planets only cosmic objects having a primal pump with a comparatively eminent temperature. For ideal , the temperature in the condense of Jupiter is estimated to kick in 20 000 K. As currently Sedna lies astir(predicate) 13 trillion miles from the middle(a) of the solar system , the info some the object is quite a scarce. At the utmost(a) point of the compass of Sedna exceed from the Sun reaches colossal size - cxxx billion miles .'
