A star is like a living thing. they are born, go through a life cycle, then die
NEBULA: is a large cloud of gas and dust that spread out in immense volume. Gravity can pull some of the gas and dust in a nebula together
NEBULAR THEORY: according to this theory the sun and planets formed from a rotating disk of dusk and gases. as speed rotation increased the center of disk flattens. Matter becomes more concentrated in this center, where the sun eventually forms.
our SUN is a LOW-MASS STAR and takes BILLIONS of years to USE UP its nuclear FUEL
PROTOSTAR: cloud pulled together is called a protostar, which is the earliest stage of the star's life
LIFE SPAN OF A STAR: a star's MASS determines how long it will live
RED GIANT: start to run out of fuel, outer layers expand becoming red giants
PLANETARY NEBULA: outer parts grow larger and drift out into space, forming a planetary nebula
WHITE DWARF: Blue-white core left behind cools leaving a white dwarf
HIGH MASS STARS: quickly evolve into supergiants
SUPERGIANTS: when runs out of fuel it can explode into a supernova. remains become a neutron star or black hole
NEUTRON STARS: supernova of a high-mass star leads into a neutron star. it is smaller and denser than a white dwarf
BLACK HOLE: has gravity so strong not even light can escape it. after massive star dies in a supernova explosion, the gravity of the mass is so strong that the gas becomes dense and packs
