Astronomer Job Description

Though you may have heard of the job title astronomer, you may be unsure-as most are-as to what exactly one is and does. While their functions are often very different, it is not uncommon for people to confuse astronauts with astronomers. The astronaut is one who travels to study the galaxy and its parts; whereas an astronomer is more concerned with studying the science, math, and particles that make up space from the ground. This is, of course, a very basic definition of the astronomer, and therefore, we will offer a much more in-depth look at just what the job description is for an astronomer-to help you decide if this is the right career path for you.

First, it should be introduced that an astronomer cannot just have an interest in the stars and planets-that they must also be thoroughly enthusiastic and well-versed in science and math-and how these two apply to the stars, planets, and galaxy. Astronomers study the sun, moon, planets, nebulae, galaxies, and other celestial bodies; but this is certainly not all. Astronomers take measurements of objects and distances between objects in the sky, determine shapes, brightness, motion, planetary positions, and analyze all things related to the solar system and beyond for a variety of purposes.

For these means of study, astronomers need not only the highest technological advancements in tools and equipment; but also extensive background in various sciences and math to understand what these measurements and results mean. Common scientific tools used by astronomers are: telescopes, optical and radio devices, micrometers, cameras, spectrometers, photometers, radiometers, satellites, and space probes.

As mentioned above, it is not just for understanding of the general galaxy that astronomers work to measure and analyze all that occurs and is housed out there; but also, for a variety of other more specific purposes. What are these fields of study and advancement? Some astronomers’ main function is to study the motions of planets and celestial bodies in relation, such as the Earth, Sun, and Moon-to determine exactly how long our seasons are, day/night, and any other differences that may exist according to these movements. Moreover, other astronomers develop positional tables of planets for air and sea navigation purposes. Other astronomers study the history of the universe, its structure, stars, and planets and compare it to the present to predict new scientific theories. Still other astronomers are responsible for developing and creating new study instruments for astronomical study, as they are the only branch of specialists who know what is necessary to make an instrument effective and innovative. Furthermore, many astronomers focus on one area of the science, such as: extragalactic astronomy, cosmology, stellar astronomy, or stellar astrophysics.

On a more general basis, an astronomer can expect to be constantly studying what is new and history to the field of the universe-as regards its most main elements: stars, planets, sun, moon, and galaxies. Along with the study, astronomers often also help innovate the field by creating and implementing new innovations for its further study and innovation-such as in the fields of space flight and satellite communications/navigation.
