electromagnetic radiation : The type of radiation that is studied consists of electric and magnetic disturbances that travel through space as waves
telescope : collects electromagnetic radiation from a distant object and focuses it at a point where the image can be studied or recorded
interferometry : process of linking separate telescopes together to act as one telescope
spinoffs : More than 1400 NASA technologies have been passed on to commercial industries and are commonly called ______
albedo : the amount of sunlight that its surface reflects
retrograde motion : a planet would move in the opposite direction across the sky
Nicolaus Copernicus : suggested the Sun to be the center of the solar system in 1543
perihelion : When a planet is closest to the Sun in its orbit
Pluto : dwarf planet
interstellar clouds : Stars and planets form from clouds of gas and dust
solar nebula : The disk of dust and gas that formed the Sun and planets
coronal holes : act as an "escape route" for solar wind
fission : splitting of heavy nuclei into smaller, lighter nuclei
binary stars : only two stars are bound together and orbit a common center of mass
