DO STARS HAVE A LIFE CYCLE LIKE US ALSO ? IF YES , WHAT IS IT ?
YES , STARS DO HAVE A LIFE CYCLE LIKE HUMANS . THE PROCESS OF THE LIFE OF STARS CAN BE DESCRIBED AS FOLLOWS :-
- THE BIRTH – STARS TAKE BIRTH IN CLUMPS OF DUST AND GAS KNOWN AS NEBULAE . CLUMPS THEN ARE PULLED TOGETHER BY THEIR OWN GRAVITY .
- PRE-SHINING – AS EACH CLUMP PULLS ITSELF TIGHTER , THE CLUMP BECOMES HOT , BUT STILL DOES NOT SHINE
- SHINE ! SHINE ! SHINE – SMALLER CLUMPS GET OUT OF THE NEBULAE AS BROWN DWARVES . AS SOON AS THE CLUMP REACHES A VERY HIGH TEMPERATURE OF 10 MILLION°C , NUCLEAR FUSION TAKES PLACE AND THE CLUMP CONDENSES TO BECOME A GLOWING STAR !
- GROWING STEADY – AS THE HEAT INSIDE THE STAR TRIES TO MAKE IT BIGGER , THE GRAVITY INSIDE STOPS IT FROM DOING SO . SO IT STAYS IN THE SAME STATE FOR BILLIONS OF YEARS .
- GOING BIGGER AND REDDER – AS THE HYDROGEN IN THE STAR BURNS UP , THE CORE OF THE STAR SHRINKS AND FUSES HELIUM ATOMS TOGETHER . THEN THE OUTER LAYERS OF GAS COOL AND SWELL , FORMING A RED GIANT .
- THE DOWNFALL – MORE CHANGES START TAKING PLACE IN THE STAR AND STAR STARTS TO TAKE IN MORE ENERGY THEN GIVING IT OUT , CAUSING IT TO COLLPASE IN SECONDS .
- THE DEATH – THE COLLAPSE RESULTS IN A HUGE NUCLEAR EXPLOSION KNOWN AS SUPERNOVA WHICH SHINES AT THE BRIGHTNESS OF MILLIONS OF SUNS .
