Words and meanings to learn
protostar

nebula
a huge cloud of gas and dust in space where stars are formed by the force of gravity pulling the material together
main sequence star
the long, stable stage of a star’s life when hydrogen nuclei fuse to form helium and the outward pressure from fusion balances the inward pull of gravity
supernova

neutron star
the dense core left behind after a supernova, composed almost entirely of neutrons and containing more mass than the Sun in only a few kilometres’ diameter
