Across
- 1. a area of space that has such a strong gravitational field that no matter or radiation can escape
- 5. a small blue or white star near the end of it's life cycle
- 6. a star that has a much faster process of fusing hydrogen and helium with in it's core
- 9. a massive star that expands and cools once it has used up all of it's hydrogen fuel
- 10. a dense nebula that forms stars by contracting both gas and dust
- 14. a star's second stage where it's size is considered a normal size
- 15. a contracting mass that resembles the early stages of a star's formation
Down
- 2. star that spends billions of years fusing hydrogen and helium with in their core
- 3. a large star that expands and cools once it has used up all of it's hydrogen fuel
- 4. a large cloud of gas that is created when the outer layers of a red giant drift into space
- 7. a star that increases in brightness due to an explosion that removes a large amount of mass
- 8. a star's second stage where it's size is considered larger than usual
- 11. a cloud that consists of gas and dust
- 12. a star that stops giving off energy x
- 13. a small dense star made up of neutrons; remains of a star that exploded as a supergiant
