- - - - definion -everything that exist,that has existed &everything that will exist
        
        (a)composition of the universe
        
        1.dark energy&dark matter(95)
        
        2.the rest(5%)
        
        1(a)its cannot be observed directly ,non visible object,based on hypothetical concept,its also known as weakly interactive massive particle(WIMP)
        
        types WIMP grevity ,eletro,week&strong nuclear force
    - - age 13.8 billion year
        
        length 93 light yerars
    - - (a)its a celestial body that genarates light by nuclear reaction&is held by its own gravity
        
        formation of stars
        
        i.its originate from nebula.gravitation the pulls together the dust and gas from the nebula to form of protostar. ii.these cloud of dust& hydrogen gas then collapses under own gravity .
        iii.the centre of this cloud become is very hot its lead to nuclear fusion.
        iv.the process release so much energy,that
        the star then shine there own light
        
        galaxy :system of stars bound by force by gravity,its include dust,hydrogen,helium
        
        sun:heart of solar system,main sequence star,also called G2V .Distance b/w the sun &earth by 151.79 km.light to travel sun to earth is 8 min 9 sec its called(1 astronomical unit
        
        layers of sun
        
        2 more items...
        
        sunspots :black spots to the sun,10 times bigger than earth,it follow 11 years cycle
        
        1 more item...
    - - inner planets
        
        1.mercury:smallest planet in solar system &2nd hottest planet,&its have no natural satellite.
        
        outer planet
        
        3.jupiter :largest planet of solar system,rotation in 9 hours,its have thin ring system,largest mountain called ganymede.great red spots to be see,its continued in 200/300 years,asteroid belt separated jupiter&mars
        
        4.saturn:founded by galio ,thick set of ring system,2nd biggest planet.its satellite mainly composed on ice among them 2 of show signs of geological activity
        
        1.neptune:its purely on gas.to be see the great dark spots
        
        2.uranas:its rotated east west.it is coldest planet.
        
        big bang theory
        
        most acceptable theory,with the evolution of universes,as per theory chronology is
        
        1.initially there was gravitational singularity which means, infinite density&temperature is bought to have contained in infinidesmally small point .

        planet : its a astronomical body orbiting a star that

        2.venus:hottest planet in solar system,its also known as earth sister or twin of earth.it rotated east west to the sun.
        
        3.earth:its only planet is life is exist.goldilocks zone.recent study indicate that earth rotations to be slowly.
        
        4.moon:its is known as red planet.its a astronomical body,and 5 largest satellite in solar system
