What are the categories of astronomy and what are the sub disciplines of astronomy?

I'm coming to you. Astronomy can be divided into two main types: theoretical astronomy and observational astronomy. Astronomer observers observe the sky for many years and collate the information they get before theoretical astronomers can develop new theories to explain and do so.

Astronomical habits are classified according to research methods and means of observation.

According to the research methodology, astronomy can be divided into:

Astrometry.

Celestial mechanics Astrophysics: The study of the application of physics to astronomy and the use of physics to interpret the results of astronomical observations.

According to the means of observation, astronomy can be divided into:

Optical astronomy.

Radio astronomy.

Infrared astronomy.

Space astronomy.

Other more subdivided disciplines are: History of Astronomy - Amateur Astronomy - Cosmology - Galactic Astronomy - Supergalactic Astronomy - Far Infrared Astronomy - Gamma Ray Astronomy - High Energy Astronomy - Radio Astronomy - Solar System Astronomy - Ultraviolet Astronomy - X-ray Astronomy - Astrogeology - Plasma Astrophysics - Relativistic Astrophysics - Neutrino Astrophysics - Geodetic Astronomy - Planetary Physics - Cosmic Magnetohydrodynamics - Cosmochemistry - Cosmic Gas Dynamics - Lunar Surfaces - Lunar Qualities - Kinematic Cosmology - Photographic Astrometry - Neutrino Astronomy - Azimuth Astronomy - Nautical Astronomy - Aeronautical Astronomy - Extragalactic Astronomy - Stellar Astronomy - Stellar PhysicsPost-Newtonian Celestial Mechanics - Basic Astrometry - Archaeological Astronomy - Space Astrometry - Almanac Astronomy - Spherical Astronomy - Radio Astrometry - Radio Astrophysics - Measured Astrophysics - Practical Astronomy - Solar Physics - Solar System Chemistry - Galaxy Dynamics - Galaxy Astronomy - Astrobiology - Astronomical Evolution - Astronomy Geodynamics - Astrodynamics.

Hope it helps!

In astronomy, three sub-disciplines have been formed: astrometry, celestial mechanics and astrophysics.

According to the classification of observation methods, several sub-disciplines of optical astronomy, radio astronomy and space astronomy have been formed.

Astrometry Celestial mechanics Astrophysics These three branches are also subdivided down a lot.

a.Astromolecular Studies, Astrophysics, Scattered Astrometry.

b.Astrometry, Astromolecular Orange and Astrophysics.

c.Astrometry, celestial mechanics and astromolecular mechanics.

d.Astrometry, celestial mechanics and astrophysics.

Correct flush answer: d

<> "Astronomy" is the studyCosmic space bodiesThe structure and development of the universeof disciplines. The content includes the structure, nature and operation of celestial bodies. Astronomy is an ancient science, and it has played an important role since the beginning of human civilization.

Professional direction

The discipline of astronomy is mainly divided into:AstrophysicsAstrometry and celestial mechanicsAstronomical techniquesThree professional orange dusts.

Professional colleges

There are double first-class universities in China in the field of astronomyNanjing UniversityUniversity of Science and Technology of China

Direction of employment

Astronomy graduates can engage in research, teaching and practical work in Yuanshen Zen astronomy and other related disciplines (physics, mathematics, astronautics, geophysics) in astronomical observatories, research institutes, universities and other units.

There are too many traces of this party's letter.

1. Macroscopically, including the discovery of extragalaxies and the measurement of the cosmic extent.

2. Microscopically, study the operation of specific galaxies, Centauri, Andromeda, solar system and other celestial bodies.

3. Theoretically, the most important thing in studying the theory of the development of the universe is the theory of the great universe.

4. In terms of exploration, look for extraterrestrial creatures and find a planet that can be used as human survival.

5. In terms of research, including academic research on black holes, four-dimensional space, space-time tunnels, etc.

6. In terms of protection, study the law and development of celestial motion, including the monitoring of asteroid belts. Keeping the planet safe.

7. Academically, the study of matter and antimatter. For the presence of faster-than-light and other studies.

8. Technically, launch the Explorer, Discoverer and other brigades and study the Martian landform, whether there is water, etc.

9. Religiously, study whether the universe was created by God, and so on.

The characteristics of Chinese astronomy do not include the following:

Ancient Chinese astronomy is astrometry.

Astronomy is one of the oldest natural science disciplines. The content of early astronomy was, by its very nature, astrometry. As early as the Neolithic Age, Chinese ancestors noticed that phenology and the periodic changes of celestial phenomena were closely related, so they began to observe celestial phenomena such as the sun and the moon.

Since then, the Chinese have been working hard for a long time to observe and record celestial phenomena, and have made brilliant achievements, leaving records of various types of sunspots, comets, meteors, novas, etc. These celestial chronicles are not only detailed and chronological, but many of them are the earliest records in the world, and still play an important role in the study of modern astronomy.

Ancient Astronomy:

The development of the calendar and astronomy is closely linked, and China is one of the earliest countries in the world to produce astronomy, and it is also one of the first countries to have a calendar. More than 5,000 years ago, China had a lunisolar calendar, which has 366 days a year. During the Shang Dynasty (1600 BC and 1066 BC), there was a special ** responsible for the astronomical calendar, when the Duan potatoes were picked with the "luni-solar calendar", and the leap month was placed at the end of the year, called "thirteen months".

During the Western Zhou Dynasty (1066 B.C. 771 B.C.), astronomers used gui and table to measure the shadow of the sun, and determined the winter solstice, summer solstice, and the 24 solar terms of the year to guide agricultural and animal husbandry production.
