All stars fuse
hydrogen
nuclei into
helium
in
nuclear fusion
Large
stars
larger stars fuse
hydrogen
nuclei into
lithium
and other
light
metals
Supernovae
a
supernova
produces enough
energy
for
hydrogen
nuclei to form elements
heavier
than
iron
All of the
naturally
occurring elements are produced by
nuclear fusion
in stars.
Life Cycle of a Star like the Sun
gravity
pulls
gas
and
dust
together to form a
protostar
main sequence
star formed, powered by
nuclear fusion
the star
expands
, becoming a
red giant
star cools and
collapses inwards
, forming a
white dwarf
star completely cools and becomes a
black dwarf
, no
light
or
heat
emitted anymore
A supernova produces enough
energy
for
hydrogen
nuclei to form elements
heavier
than
iron.
A star begins when a
nebula
(a cloud of dust and gas)
collapses
under
gravity
to form a
protostar
Life Cycle of a Large Star
gravity
pulls
gas
and
dust
together to form a
protostar
main sequence
star formed,
powered
by
nuclear fusion
the star
expands
, becoming a
red supergiant
the star
explodes
in a
supernova
the
supernova
leaves behind either a
black hole
or a
neutron star
