Across
- 2. Large star that dies in a supernova explosion and has such a strong force that not even light can escape
- 3. Formed when a massive star runs out of fuel and its core collapses. Primarily composed of neutrons
- 5. Nursery for stars
- 8. The remaining hot and dense core of a star that has burned up all of its fuel
- 9. Massive star that no longer has hydrogen to burn in its core
- 10. "Failed star" that was unable to reach a high enough temperature to perform hydrogen fusion
- 11. An explosion when a massive star reaches the end of its life and collapse, radiating a large amount of energy
- 12. The process in which two hydrogen nuclei combine to form one helium nucleus
Down
- 1. Formed after a red giant has shed its outer layers and is dying
- 4. Young developing star that is too small to perform nuclear fusion
- 6. A star that gets bigger as the hydrogen core starts to burn.It turns red due to a temperature change
- 7. A star that has begun nuclear fusion, increasing in temperature. This is the stage a star will spend most of its life
