What is the Doppler effect--red/blue shift?
300
The 2 most common elements in which stars are composed of.
What are hydrogen and helium?

What are the differences betw an average star's life and a hypergiant star's life?
Main difference is in there death stage--average forms a white dwarf, where a hyper goes supernova and then neutron star or black hole
