fast chapter Flashcards
constellations
Many names are given to these group of stars by ancient cultures remain today
radio telescope
collects and amplifies radio waves
light- year
is the distance light travels in one year
spectroscope
uses a prism or diffraction grating so separate light into its components wave lengths
nebula
stars form from a large clouds of gas, ice, dust
main sequence
stars included the broad band of stars from hot,and bright stars
giant
a star where the temp increases
white dwarf
stars outer layer into space leaves hot dense core

convex lens
what does a reflecting telescope use
mirror
what are the two names of the optical telescopes
reflecting telescope and refracting telescope
why are space telescopes better than ground based telescope
doesn’t have many interruptions (clouds, pollution)
what are the names of the two space telescopes that are in space
Chandra X-ray observatory, Spitzer Space telescope
what are the three thing a spectroscope can determine
surface temp, chemical composition whether its moving from or toward earth
what are blue light waves
waves that detect stars closer to earth, waves show up blue and is more frequent
what are red light waves
stars father away from earth waves are more wide spread and appears red on the wave lengths
