1. | Fusion | A. | a region of spacetime from which gravity prevents anything, even light, from escaping | |
2. | Nebula | B. | a measurement of how bright a star appears in the night sky | |
3. | Isotope | C. | a reference star that is used to calculate the distance to other stars | |
4. | Neutrino | D. | atoms of the same element that have different masses due to having a different number of neutrons | |
5. | Positron | E. | the remains of a white dwarf that has cooled down to the background temperature of the universe | |
6. | Deuterium | F. | a body formed by the collapse of a nebula that does not have enough mass to trigger fusion | |
7. | Gamma Ray | G. | the final end stage for small stars after most of the nuclear fuel has been spent | |
8. | Protostar | H. | a measurement of the rate of energy being released by a star | |
9. | Red Giant | I. | a small very dense object in space composed of neutrons | |
10. | Black Hole | J. | the stage in a star life cycle where the nebula has collapsed, but fusion has not yet begun | |
11. | Brightness | K. | the amount of light reaching us from a star; it depends on the luminosity and the distance | |
12. | Luminosity | L. | a high energy, high frequency photon of electromagnetic radiation | |
13. | Black Dwarf | M. | the combining of two small nuclei to form larger heavier nucleus | |
14. | Brown Dwarf | N. | a large star with high luminosity and low surface temperature that forms as the hydrogen in the core is used up | |
15. | White Dwarf | O. | the antiparticle of an electron, it has the same mass as an electron, but a positive charge | |
16. | Neutron Star | P. | a neutral subatomic particle with a very small mass that rarely reacts with matter | |
17. | Main Sequence | Q. | the band of stars that stretch form hot, luminous stars to cool stars with a low luminosity on an HR diagram | |
18. | Standard Candles | R. | a cloud of gas and dust in outer space | |
19. | Absolute Magnitude | S. | a measurement of how bright a star would be at a distance of one parsec | |
20. | Apparent Magnitude | T. | an atom of hydrogen with a neutron, so with an atomic mass of 2 |
