what is the steps to make all of the elements
the big bang, nuclear fusion, then a supernova
what elements are formed during the big bang
hydrogen and helium
what elements are formed during nuclear fusion
carbon, oxygen, nitrogen
what elements are formed during a supernova
every other element
what is a stellar nevula
where every star is born and begins its life, it is a cloud of dust, hydrogen, and helium
what is a planetary nebula
it doesn’t explode but its outer area shoots off and it is a ring of gas and debris is left over, they are very pretty
what is a white dwarf
after stars run of out nuclear fuel, it is the left over core, very dense and can be very hot
what is a neutron star
the collapsed core of a large star, it spins very fast and looks like its blinking
what is the life of an average star
stellar nebula, protostar, main sequence, red giant, planetary nebula, white dwarf
what is the life of a large star
stellar nebula, protostar, main sequence, super giant, supernova, neutron star
what is the life of a massive star
stellar nebula, protostar, main sequence, super giant, super nova, black hole
what is a supernova
an exploding star that burnt out of all its fuel, when there is no fuel left it will implode
what is a black hole
region of space where the gravitational pull is so strong that nothing can escape it, it is greats amoutn of matter pulled to one spot
what are the steps of the big bang theory
started as a hot dense point (singularity), it expands, it slows down cools and atoms, elements begin to form, solar systems form
what does red mean in BBT
it is moving away from you
what is evidence of the BBT
the red shift/expanding and cosmic radiation from it still being in there
what does the spectracope lab tell us
about the red shift
when were the first solar systems
4.6 billion years ago
what is cosmic background radiation
the heat from BB still around in space
whta is an emission spectrum and how do scientists use it to study stars
to see the wavelength and light emitted by a gas
