Almost all astronomers do research and require algebra. Some are theoreticians, working on the laws involving the beginnings of astronomical objects. Others analyze large quantities of data gathered by observatories and satellites, and write reports on their findings. Some astronomers actually operate, usually as part of a team, ground-based telescopes. However, astronomers may spend only a few weeks each year making observations with optical telescopes, radio telescopes, and other instruments. For many years, satellites and other space-based instruments have provided us with astronomical data. New technology resulting in improvements in analytical techniques and instruments, such as computers, telescopes, and mounts, is leading to reappearance in ground-based research. A small number of astronomers work in museums housing planetariums. These astronomers develop programs presented to the public and may direct planetarium operations.

     Many astronomers use algebra in their work to achieve their goals. With out algebra things like the Hubble Telescope, and the discovery of Pluto would not be possible. Algebra is used to measure speeds and to graph movement rates. There are a few astronomers that I found to best represent these achievements. With out them and their usage of algebra technology and science would not have been able to flourish. Our knowledge of the stars and space is based on these astronomers.
