- 4. the increase in pressure within a substance caused by rising temperatures.
- 7. a massive growing ball of gas collapsing under its own gravity.
- 9. a process in massive, hot stars where carbon, nitrogen, and oxygen act as catalysts to fuse hydrogen.
- 10. quantum mechanical effect that stops neutron stars from collapsing under their own gravity.
- 11. the cosmic process of creating new atomic nuclei.
- 12. an expanding, glowing shell of ionized gas and dust.
- 13. energy that travels from a source in the form of waves or high speed particles.
- 14. a sudden explosive onset of helium-to-carbon fusion in the dense and degenerate core of a low-mass star.
Down
- 1. a region in space with gravity so intense that not even light can escape
- 2. the dense accumulation of gas and dust located in the space between stars within a galaxy.
- 3. a primarily nuclear fusion process powering the sun and low mass stars.
- 5. a violent and luminous explosion that marks the end of a stars life.
- 6. quantum mechanical force that prevents extremely dense matter.
- 8. the stable state of a fluid where the inward pull of gravity is exactly balanced by the outward push of pressure.
