All You Need To Know About Astronomers
Astronomers are scientists who specialize in areas outside the scope of the Earth’s atmosphere. Stars, planets, moons, comets, and galaxies are observed by observational astronomers (by analyzing the data) or by theoretical astronomers. Among the topics or fields studied by astronomers are planetary science, solar astronomy, and the origin or evolution of stars. The study of the whole universe, such as physical cosmology, is related but distinct from other subjects.
Types
-
Observational and theoretical astronomers typically fall into two groups.Â
-
Observational astronomers observe celestial objects directly and analyze the results. Theoretical astronomers create and study models of things that they cannot perceive.
-
 A system of stars or a galaxy takes millions to billions of years to complete a life cycle, so astronomers must observe snapshots of different organisms at different stages of their evolution. Using these data, they create models or simulations to theorize how celestial objects work.
-
Astronomy can also be divided into planetary astronomy, galactic astronomy, or physical cosmology.
Academic
-
In the past, astronomy was more concerned with describing and classifying celestial phenomena than astrophysics was with explaining their differences and similarities using physical laws.
-
 Astrophysicists and astronomers are used interchangeably today, with these distinctions mostly gone. Typically, astronomers hold a PhD in physics or astronomy and are hired by research institutions or universities.Â
-
Most of their time is spent on research, although they frequently teach, build instruments, or operate observatories.
-
This is North America’s largest professional astronomical society, with approximately 7,000 members.
-
 Nearly 10,145 scientists from 70 countries are members of the International Astronomical Union, including those in physics, geology, and engineering whose research interests are closely related to astronomy.
Indian astronomy
The history of Indian astronomy stretches back to prehistoric times. Indian astronomy dates back to the Indus Valley Civilization or even earlier. During the Vedic period, in about 1500 BCE or earlier, astronomy emerged as an “auxiliary discipline” associated with the study of the Vedas. Vedanga Jyotisha is the oldest known text, dating from 1400–1200 BCE (the extant form may date from 700 to 600 BCE).
Greek astronomy influenced Indian astronomy in the early centuries of the Common Era, for example, in the Yavanajataka and the Romaka Siddhanta, a Sanskrit translation from the 2nd century of the Greek text.
