What is astronomy?

Astronomy is one of the most beautiful and adventurous hobbies. According to the American Museum of Natural History, astronomy is the study of every celestial object in the universe, like the sun, moon, planets, galaxies, space, black holes, supernovas, stars, nebulae, etc. Then what is astrology?

 

Difference between Astronomy and Astrology

People often confuse astronomy and astrology. Astronomy is the study of the universe and is a branch of science. Astrology is a nonscientific study in which people use the position of the stars and planets to predict a person’s future or a future event, says Dictionary.com.

Astronomy uses various equipment such as telescopes and binoculars, whereas astrology involves horoscopes (a map of the positions of stars and planets). It is believed that the person’s future aligns with a constellation or zodiac sign that was in the sky when the person was born.

 

History of Astronomy

Astronomy is one of the oldest sciences. Ancient civilizations such as the Babylonians, Greeks, Egyptians, etc. made important contributions to the field by recording various celestial events and creating the early model of the universe. Later, Ptolemy proposed the geocentric model (a model of the solar system in which the Earth was believed to be at the center of the universe).

However, the Renaissance period was when the real evolution started. A famous astronomer, Nicolaus Copernicus, proposed the heliocentric model (a model of the solar system in which the sun was at the center of the universe). Galileo’s telescopic observations and Kepler’s laws of planetary motion later accepted this model.

And over centuries, discoveries, from Isaac Newton’s laws of gravity to Edwin Hubble’s revelation of the expanding universe, have transformed our understanding of space, making astronomy a continually evolving science.

 

Branches of Astronomy

There are various branches of astronomy, like observational astronomy, theoretical astronomy, astronomy, cosmology, and planetary science.

  • Observational astronomy: Observational astronomy is the study of the observable universe by using instruments such as telescopes and other equipment.
  • Theoritical astronomy: Theoritical astronomy is the branch of astronomy that involves the use of physics, chemistry, and other branches of sciences to explain astronomical events and phenomena.
  • Astrophysics: Astrophysics is a study that involves studying the physical characteristics of the celestial bodies.
  • Cosmology: Cosmology studies the events that lead to the foundations of the universe and other celestial objects that we observe today.
  • Planetary Science: This includes the study of planets and their systems, inviolating moons, rings, structure, formation, size, and other related characteristics.

 

Astronomy as a career

Astronomy is one of the most exciting and adventurous hobbies. It is also a continuously growing sector as humans are getting more involved in exploring and unfolding the mysteries of the universe. According to the Bureau of Labour Statistics, the overall employment rate of astronomers and physicists will increase by 7% between 2023 and 2033, which is faster than any other occupation.

Thus, we can say that choosing astronomy as a career is beneficial, as there will be several job opportunities for an individual.

One can get jobs at government space agencies like NASA, ESA, and ISRO or other private space companies like SpaceX, Blue Origin, etc. There are several companies to choose from.

 

Necessary Skills

To excel in astronomy, a strong foundation in various technical and analytical skills is essential. A deep understanding of physics and mathematics forms the backbone of astronomical research, as these subjects explain the fundamental forces and phenomena governing celestial bodies.

Proficiency in computer programming, particularly in languages like Python or MATLAB, is crucial for analyzing vast datasets, running simulations, and modeling astronomical systems. Critical thinking and problem-solving abilities are also vital, enabling astronomers to interpret complex observations and develop theories.

Additionally, familiarity with data analysis tools and software used for image processing, such as those handling telescope data, is important for deriving meaningful conclusions from observations. Strong communication skills are essential for writing research papers, collaborating with other scientists, and conveying findings to both scientific and general audiences.

 

Academics and Education

The educational path to becoming an astronomer typically begins with a strong emphasis on science and mathematics in high school, focusing on subjects like physics, mathematics, and chemistry. Afterwards, pursuing a bachelor’s degree in astronomy, astrophysics, or physics is essential, as these programs provide a comprehensive understanding of the universe’s mechanics.

During undergraduate studies, students are encouraged to engage in internships, research projects, or observatory work to gain practical experience. For more advanced roles in research or academia, a master’s degree or a Ph.D. is required.

Graduate studies allow for specialization in fields such as planetary science, cosmology, or stellar astronomy. Participation in research, publishing papers, and collaborating with scientific teams during this period is crucial for building expertise. Continuous learning and staying updated with the latest advancements through workshops, conferences, and online courses are also integral to a successful career in astronomy.

 

How much does an astronomer make?

Astronomers’ salaries vary significantly based on education, experience, location, and the sector they work in. Entry-level astronomers, often with a bachelor’s degree, can expect starting salaries of around $50,000 to $80,000 per year. Those with advanced degrees like a PhD and more experience earn substantially more, with mid-level salaries averaging between $86,000 and $98,000 annually, according to PayScale and Jobted.

The average salary for an astronomer in 2024 in the U.S. is approximately $90,470 per year. However, astronomers working in high-paying industries, such as government agencies like NASA, can earn up to $171,650, as reported by Osum.

The location also plays a role, with astronomers in California earning a mean wage of about $149,390, and in India, the average salary of an astronomer is around ₹9,96,640 per year as stated on Glassdoor.com.

 

A Degree in Astronomy or Astrophysics

To become an astronomer, it is essential to pursue your academics and studies concerning the field. As discussed before, it is essential to pursue your secondary higher education in a science field, and getting a bachelor’s in astronomy, astrophysics, or physics, and then a master’s and a PhD in astronomy is essential to becoming an astronomer. However, finding a good college and degree is essential. Here are some of the best colleges worldwide that offer undergraduate and graduate degrees in astronomy and astrophysics.
