1.3 Flashcards
A spectrum that contains dark lines superimposed on a bright continuous spectrum. Also called a dark-line spectrum.
Absorption Spectrum
A pair of stars that orbit one another
Binary Star
the phenomenon in which light from a source that is moving toward an observer is shifted toward the blue end of the spectrum.
Blue shift
A star that expands and contracts in a regularly repeating cycle
Cepheid Variable
A spectrum of colored lines on a dark background also called a bright line spectrum
Emission Spectrum
A bright very large star with a low density and a relatively low surface temperature
Giant star
A cloud of gas and dust in interstaller space
Nebula
The phenomenon in which light moving rapidly away from an observer appears shifted towards the red end of the spectrum
Redshift
The band of colors produced when light is passed through a prism or similar device
Spectrum

Redshift
The cooled remnant of the first light light that could ever travel freely throughout the universe
Cosmic Microwave Background
light observed from distant stars and galaxies gives evidence that the universe is expanding (moving away from a central point). This allows for Big Bang Theory, because after a “bang” occurs all of the matter moves away from the point of origin.
