Across
  1. 2. the process of adding/accumulating matter
  2. 3. hypothetical black hole that would provide a shortcut through space and time.
  3. 5. Any collection of dust/particles in space.
  4. 8. The process that a star must reach in order to create its heat and energy
  5. 9. made of plasma, held together by gravity
  6. 10. when the forces of pressure from inside a star and the force of gravity acting upon a star are equal.
  7. 15. when the star is still accreting, or gathering mass.
  8. 16. prevents the star from collapsing from gravity
  9. 17. What stars like our Sun become once they have exhausted their fuel; After the Red Giant stage
  10. 19. Can be either red or blue
Down
  1. 1. stars that never accreted enough mass to sustain hydrogen fusion
  2. 4. At the end of a star’s lifetime; star collapses in and then explodes.
  3. 6. The longest stage of a star, when it is most stable.
  4. 7. A star made of only neutrons.
  5. 11. Much brighter and larger than a red giant; heat from nuclear fusion
  6. 12. brightness of the star compared to the sun.
  7. 13. A white dwarf that has cooled down and lost all of its heat
  8. 14. A collapsed larger star, of extreme density, gravity prevents anything from escaping.
  9. 18. depends on mass and distance between 2 objects
  10. 20. the 4th state of matter
