Big Bang Theory By Maddison Gretton
24
absorption spectrum: A spectrum of electromagnetic radiation transmitted through a substance, showing dark lines or bands due to absorption of specific wavelengths.
alpha centauri: The third brightest star in the sky, in the constellation Centaurus, visible only to observers in the southern hemisphere. It is the nearest bright star to the solar system, and is a visual binary.
astrology: The study of the movements and relative positions of celestial bodies interpreted as having an influence on human affairs and the natural world.
astronomy: The branch of science that deals with celestial objects, space, and the physical universe as a whole.
beta centauri: The second brightest star in Centaurus.
betelgeuse: The tenth brightest star in the sky, in the constellation Orion. It is a red supergiant, and variations in its brightness are associated with pulsations in its outer envelope.
big bang theory: The theory that the universe originated sometime between 10 billion and 20 billion years ago from the cataclysmic explosion of a small volume of matter at extremely high density and temperature.
blue shift: A decrease in the wavelength of the radiation emitted by an approaching celestial body as a consequence of the Doppler effect; a shift toward the short-wavelength end of the spectrum.
celestial bodies: Natural objects visible in the sky.
constellation: A group of stars forming a pattern that is traditionally named after its apparent form or identified with a mythological figure.
cosmic microwave background radiation: The cooled remnant of the hot big bang that fills the entire universe and can be observed today with an average temperature of about 2.725 kelvin.
crab nebula: An irregular patch of luminous gas in the constellation Taurus, believed to be the remnant of a supernova explosion seen by Chinese astronomers in 1054. At its center is the first pulsar to be observed visually, and the nebula is a strong source of high-energy radiation.
doppler effect: An increase (or decrease) in the frequency of sound, light, or other waves as the source and observer move toward (or away from) each other. The effect causes the sudden change in pitch noticeable in a passing siren, as well as the redshift seen by astronomers.
emmission spectrum: A spectrum of the electromagnetic radiation emitted by a source.
galaxy: A system of millions or billions of stars, together with gas and dust, held together by gravitational attraction.
hubble law: The generalization that the speed of recession of distant galaxies (the red shift) is proportional to their distance from the observer.
orion the hunter: A prominent constellation located on the celestial equator and visible throughout the world. It is one of the most conspicuous, and most recognizable constellations in the night sky.
planisheres: A map formed by the projection of a sphere or part of a sphere on a plane, esp. an adjustable circular star map that shows the appearance of the heavens at a specific time and place.
pseudoscience: A collection of beliefs or practices mistakenly regarded as being based on scientific method.
red shift: A shift in the spectra of very distant galaxies toward longer wavelengths, generally interpreted as evidence that the universe is expanding.
rigel: The seventh brightest star in the sky, and the brightest in the constellation Orion. It is a blue supergiant nearly sixty thousand times as luminous as our sun.
sirius dogstar: The brightest star in the sky, south of the celestial equator in the constellation Canis Major. It is a binary star with a dim companion, which is a white dwarf.
steady state theory: The theory that the universe maintains a constant average density with matter created to fill the void left by galaxies that are receding from each other.
supernova: A star that suddenly increases greatly in brightness because of a catastrophic explosion that ejects most of its mass.
transit of venus: A transit of something across the Sun takes place when the planet something passes directly between the Sun and Earth, obscuring a small portion of the solar disk.
