Glossary

1. Cosmic rays: Nuclear and subatomic particles moving through space at speeds close to the speed of light.
2. Red shift: When the light an object emits is displaced toward the red end of the spectrum it is said to be red shifted.
3. Blue shift: When the light an object emits is displaced towards the blue end of the spectrum is said to be blue shifted.
4. Spectrum: The distribution of wavelengths and frequencies.
5. Absorption spectrum: A continuous spectrum interrupted by dark lines characteristic of the medium through which the radiation has passed.
6. Emission spectrum: A unique series of spectral lines emitted by an atomic gas when a potential difference is applied across the gas.
7. Atomic Spectrum: A spectrum of radiation caused by electron transitions within an atom.
8. Motion: A natural event that involves a change in the position or location of something.
9. Density: The amount per unit size.
10. Acceleration: The rate of change of velocity.
11. Velocity: Distance traveled per unit time.
12. Fusion: An occurrence that involves the production of a union.
13. Temperature: A measure of the average kinetic energy of the particles in a substance.
14. Gravitational force: The mutual force of attraction between particles of matter.
15. Quasars: Very small bet brilliantly luminous extragalactic systems, found only at great distance.
