What is the fate of a star much more massive than the Sun at the end of its life cycle?

• It becomes a white dwarf

• It turns into a neutron star

• It explodes as a supernova and may leave behind a black hole

• It simply fades away into the cosmic background

What is a white dwarf?

• A newly formed star

• The final stage in the life cycle of a low to medium mass star

• A massive star undergoing a supernova explosion

• A nebula that is just beginning to form stars

What evidence supports the Big Bang Theory?

• The observation of galaxies moving away from us, indicating the universe is expanding

• The detection of planets in other solar systems

• The presence of dark matter in the universe
