constellations
collects ans amplifies radio waves
radio telescope

light year
uses a prism of diffraction grading to seprate lights into
into its componet wavelengths
spectroscope
stars form from a large cloud of gas iced and dust called a
nebula
stars includethe board band of stars from hot brightt stars in upper left corner of the diagram
main sequence
the stars core contracts the tempature increases and the star envolves into a
giant star

what are the three things that a spectroscope determine
