What is Astronomy? Details about astronomer – ScientificAsia

What is Astronomy? The study of astronomy includes everything in the universe besides our planet’s atmosphere. That includes celestial bodies like the Sun, Moon, planets, and stars that we can see with our unaided eyes. It also includes things like far-off galaxies and small particles that we can only glimpse through telescopes or other tools.

An astronomer is what?

The stars appear as lovely glittering lights when you look up at the sky at night. An astronomer is interested in understanding the nature of the stars and other celestial objects as well as their beauty. A scientist who studies the universe beyond Earth and the universe as it pertains to Earth is called an astronomer. Astronomers work to create a picture of the Universe’s past, going all the way back to the “Big Bang,” using observational instruments like computers, ground- and space-based observatories, as well as the good old paper and pencil. 

To accomplish this, astronomers must comprehend how matter behaves in environments that are simply not present on Earth, whether they include extremely high temperatures or strange substances and particles. To piece together what occurs outside of our globe, they must employ advanced computers and any light—from radio to gamma rays—and particles—from cosmic rays to neutrinos—that make it to Earth. Observational astronomers may strive to map the entire sky, find new planets, or explain stars, galaxies, black holes, and other phenomena. To better understand how galaxies develop and how the universe expanded, more theoretical researchers may study magnetic fields or mimic the structure of stars. 


A modern astronomer must have a strong foundation in math, physics, chemistry, and computer science, which calls for a scientific high school curriculum, a university degree in physics, math, or engineering, and a PhD in astronomy or astrophysics. 

What kind of work does an astronomer do?

Astronomers typically work in one or more postdoctoral posts at universities or research organizations for three to six years after receiving their PhD. After that, astronomers look for long-term jobs as researchers or team leaders at government research centers, national facilities, or university departments. Astronomers eventually receive university tenure, which is a permanent job that they typically hold for the duration of their careers.  Despite being a tiny field, astronomy is immensely popular.

Only those with a strong background in the field, exceptional talent, and intense passion for it stands a chance of landing a permanent post. But astronomy training can open doors in a wide range of linked industries, including other scientific domains, industrial research, commercial or industrial companies, teaching, public relations, and outreach.

Things to consider when training for a profession in astronomy

Make sure you have strong communication abilities. Throughout your academic career, writing a lot of scholarly publications will be expected of you. Writing grant bids and proposals for observing time to the various observatories may also be required of you. Also keep in mind that, like the majority of modern scientific fields, astronomy demands participation in worldwide partnerships, therefore strong English communication abilities are crucial. 

It’s important to keep in mind that many astronomers are also employed as university lecturers and professors, therefore communication and teaching abilities are crucial. Be ready to spend extended periods of time at night in observatories and to travel extensively for conferences, meetings, and observation runs, especially early on.  All the preparation will seem worthwhile once you begin to learn the mysteries of the Universe in your profession as an astronomer if you are driven enough.
