LIFE AND DEATH OF A HIGH MASS STAR

THE LIFE OF ALL STARS FOLLOWS A SPECIFIC CYCLE  ALL STARS BEGIN WHEN GAS AND DUST ARE PULLED TOGETHER BY GRAVITY.  STARS ARE AT THEIR “FULL LIFE” WHEN THEY ARE IN THE MAIN SEQUENCE STAGE.  AFTER THAT, THEY LOSE THEIR MASS AND HEAT AND BEGIN TO DIE.  THIS PROCESS TAKES BILLIONS AND BILLIONS OF YEARS.

NEBULA Gravity pulls dust and gases together

PROTOSTAR NUCLEAR FUSION OF ATOMS OCCURS CAUSING LIGHT AND HEAT TO FORM

MAIN SEQUENCE STAR THE BRIGHTEST LIFE CYCLE OF A STAR THIS IS RIGEL – ONE OF THE BRIGHTEST STARS IN SPACE

RED SUPERGIANT As hydrogen explodes releasing light and heat, helium forms. Helium is lighter and floats outward., expanding the size of the star. Since there is less hydrogen exploding, the star becomes cooler and turns red and only Carbon is left in the Core.

SUPERNOVA THE RED SUPERGIANT EXPLODES SUDDENLY FROM THE REMAINING HYDROGEN WHEN THE SUPERGIANT IS MOSTLY HELIUM IT EXPANDS OUTWARD. WITH VERY LITTLE HYDROGEN REMAINING, IT EXPLODES SUDDENLY. THREE OBJECTS CAN FORM FROM THIS EXPLOSIO N.

THREE OBJECTS CAN FORM FROM A SUPERNOVA EXPLOSION NEW NEBULA FROM THE GAS AND DUST NEUTRON STAR – THE SIZE OF A CITY, BUT LOTS OF GRAVITY

THE THIRD OBJECT THAT CAN FORM IS A BLACK HOLE IT IS NOT A HOLE IN SPACE IT IS A DEAD STAR THAT NO LONGER GLOWS OR GIVES OFF HEAT IT HAS SO MUCH GRAVITY THAT IT WILL PULL ANY GAS, DUST, OR STAR WITH LESS GRAVITY INTO IT. IT WILL ALSO PULL LIGHT INSIDE OF IT.

BLACK HOLES SINCE BLACK HOLES GIVE OFF NO LIGHT, THEY CAN ONLY BE DETECTED BY X-RAYS! THE CLOSEST ONE TO EARTH IS 1600 LIGHT YEARS AWAY, BUT IS IN OUR MILKY WAY GALAXY.

THAT WAS FARRRR OUT!!!!
