**Definitions from the Holy Year 9 Science Book **
 * Definitions from the Internet **
 * Nebula: **(plural: nebulae) An interstellar cloud of dust, hydrogen gas and plasma.
 * Protostar: **A large star that forms by contraction out of the gas of a giant molecular cloud in the interstellar medium.
 * Red Giant: **A luminous giant star of low or intermediate mass that is in a late phase of stellar evolution.
 * White Dwarf: **(also called degenerate dwarf) A small star composed mostly of electron-degenerate matter.
 * Red Supergiant: **Supergiant stars of a spectral type K or M. Largest star when it comes to volume.
 * Supernova: **(plural: supenovae) Stellar explosions. Extremely luminous and a burst of radiation that can outshine the whole galaxy, before fading over several weeks or months.
 * Neutron Star:** A type of remnant that can result from the gravitational collapse of a massive star.
 * Pulsars: **Highly magnetized, rotation neutron stars that emit a bem of electromagnetic radiation.
 * <span style="font-size: 12pt; font-family: 'Times New Roman','serif';">Planets: **<span style="font-size: 12pt; font-family: 'Times New Roman','serif';">A celestial body orbiting a star or stellar remnant that is massive enough to be rounded by its own gravity, is not massive enough to cause thermonuclear fusion, and has cleared its neighbouring region of planetismals.
 * <span style="font-size: 12pt; font-family: 'Times New Roman','serif';">Nebula: **<span style="font-size: 12pt; font-family: 'Times New Roman','serif';">Raw ingredients of a star.

 * <span style="font-size: 12pt; font-family: 'Times New Roman','serif';">Red Giant: **<span style="font-size: 12pt; font-family: 'Times New Roman','serif';">When stars the size of a sun start to die, then it is called a red giant. When a red giant is formed, it expands to 100 times its original size.
