Across
- 1. A star fusing hydrogen into helium in its core
- 4. The anti-particle of an electron
- 6. When the triple-alpha process results in a quick burst of helium fusion in the core
- 8. The largest stars turn into this when the radiative pressure from the core becomes so great that it causes the star to expand
- 11. The very small, mysterious particle emitted by nuclear processes that does not interact with normal matter
- 12. The positively charged particles in the nucleus of an atom
- 14. The next phase of the Sun's life. It will get much bigger and cool down
- 15. An area of spacetime so dense that nothing can escape it. Created by the core collapse of the largest stars
- 18. The clouds of gas and dust in space that form stars
- 19. When the radiative pressure in a red giant's core becomes so great that it begins to shed off the outer layers of its atmosphere
- 21. The Sun is technically a yellow __________________
- 22. The neutral particle in the nucleus of an atom
- 23. The very high energy light produced by nuclear fusion and other high energy processes
Down
- 2. Once the core of a red supergiant becomes iron-56, the body of the star collapses then rebounds off of the core, creating this explosion
- 3. An incredibly dense left-over of large stars. Only made of neutrons
- 5. The leftover core of a red giant that becomes revealed after the production of a planetary nebula
- 7. The diagram that plots a star's luminosity against its temperature. Used to organize stars into different categories
- 9. A very young star that is still gathering mass from its parent nebula
- 10. The nuclear fusion process that involves fusing hydrogen into helium
- 13. The end stage of sun-like stars. The universe isn't old enough for these to exist yet
- 16. The end product of the triple-alpha process
- 17. The most abundant element in the universe. Used by stars as the base of nuclear fusion processes
- 20. The negatively charged subatomic particles that orbit the nuclei of atoms
