Across
- 2. A star that is beginning to form
- 3. Stars send most of their live here, its when they give off heat, energy and light
- 6. A star that spins very fast and cannot be seen but produces regular radio signals
- 7. Light created from the birth/death of a star
- 9. A star’s way of making energy reaction in which two hydrogens come together
- 11. What star starts as an average star and grows also turns red, becomes a planetary nebula or ends up as a white dwarf (Red Giant)
- 14. A white dwarf star that becomes too cold - Dead
- 15. What contains the mass of a star, and ejects its outer layers until the stellar core is exposed
Down
- 1. A star that failed to ignite due to insufficient mass
- 4. Formed from a large star’s Supernova - Gravity is so intense light can not escape.
- 5. The colossal explosion of a star
- 6. Created by red giants after core collapses, fusion has stopped,and floats off
- 8. Extremely dense, compact stars thought to be composed primarily of a neutron - after supernova explosion
- 10. A star that temporarily becomes extremely bright and then returns to its original brightness
- 12. A small star with low-surface temperature - has not left main sequence
- 13. What star starts as a massive star and turns red eventually ends up being a supernova and has a mass 8-12 times larger than the sun
