Across
  1. 3. The point where the outward force from fusion and inward force from gravity are balanced.
  2. 5. What is a large cloud of dust and gas in space?
  3. 7. small and dense star that is left over after a supernova.
  4. 10. What is a rotating neutron star called?
  5. 11. What is the name of a failed star that does not have enough mass to undergo fusion of hydrogen to helium.
  6. 12. a luminous body of gas that shines because of fusion within the core.
  7. 13. Hot dense core leftover after the star's outer layers escape into space.
Down
  1. 1. What is left over after a red giant expands?
  2. 2. gigantic explosion when a massive star collapses.
  3. 4. What is the end state of an average mass star where the inner helium core contracts leading the outer layers to expand?
  4. 6. What is the end state of a massive star where the core collapses to a point that gravity is so strong not even light can escape?
  5. 8. What are very large stars that will end in a supernova called?
  6. 9. What is the name of a very young star that still gathers mass from its parent molecular cloud?
