Across
- 1. Primary nuclear reaction in low mass stars, that fuses hydrogen nuclei into helium
- 4. expanding shell of glowing gas ejected by low to medium stars
- 6. colossal explosion marking the death of a large star
- 10. A quantum mechanical pressure that prevents white dwarfs from collapsing
- 12. a region in space with a large gravitational pull, that not even light can escape
- 13. sensitive fusion process dominant in massive stars
- 14. stable state of a star where inward pull of gravity is exactly balanced by the outward pressure
Down
- 2. The outward pressure exerted by photons as they travel from a starts interior
- 3. powerful pressure that supports neutron stars against gravity
- 5. Very young, developing star,that has not begun hydrogen fusion
- 7. vast accumulation of gas and dust in space
- 8. Pressure generated by the kinetic energy from gas particles
- 9. explosion of helium fusion in the core of a low mass red giant
- 11. Cosmic process of creating new atomic nuclei
