12 m Telescope Astronomy at Millimeter Wavelengths Astronomy and Radio Waves Astronomy may be the oldest of the sciences. It no longer includes astrology. Modern astronomers hold doctoral degrees in physics, chemistry, or mathematics and conduct research to understand the universe and its processes.
Topics involve sizes, masses, forces, and energies impossible to duplicate in laboratories on Earth.
Cosmic Radio Waves Astronomers make use of all possible information coming from astronomical objects, even information we cannot see. For example, all objects in the universe emit radio waves naturally. We call these cosmic radio waves. Our bodies sense infra-red waves as radiant heat. At long wavelengths, cosmic radio waves tend to come from violent processes in the universe such as exploding stars or galaxies.
