  2. 5. Most stars are in this stage of the star life cycle
  3. 6. Property that determines how tightly packed matter is in an object
  4. 7. An explosion created when a high mass star (a supergiant) runs out of fuel

  9. 14. Process in which atoms combine to form heavier atoms
Down
  1. 2. An object with gravity so strong that nothing can escape it – even light
  2. 3. The remains of high mass stars that have exploded – smaller and denser than a white dwarf
  3. 4. Color of the coolest temperature stars
  4. 9. The blue-white core of a low to medium mass star that has run out of fuel
  5. 11. Type of star our Sun will become when it runs out of hydrogen
  6. 13. A contracting cloud of dust and gas with enough mass to form a star
