What are the major branches of astronomy?

ASTROPHYSICS – How the laws of physics apply to stars and celestial bodies. COSMOLOGY – How the universe was created, evolves and its ultimate fate. SPECTROSCOPY – How light reflects, absorbs and transfers between matter. PHOTOMETRY – How luminous astronomical objects are in space based on electromagnetic radiation.

How many subfields of astronomy are there?

four sub-fields
The four sub-fields of Astronomy are: Astrophysics; Astrometry; Astrogeology; and Astrobiology. The following gives a brief description of each sub-field and its focus. Astrophysics, as a scientific discipline, was born in mid-nineteenth century Europe.

What are the three branches of astronomy?

Planetary Science – study of planets, moons, and planetary systems. Atmospheric science – study of atmospheres and weather. Planetary formation – formation of planets and moons in the context of the formation and evolution of the Solar System.

What are types of astronomy?

Since the 20th century there have been two main types of astronomy, observational and theoretical astronomy. Observational astronomy uses telescopes and cameras to observe or look at stars, galaxies and other astronomical objects.

Exoplanet (also known as extrasolar planets) – planet outside the Solar System.

What are the different branches of astronomy?

Branches of astronomy Astrobiology – studies the advent and evolution of biological systems in the universe. Astrophysics – branch of astronomy that deals with the physics of the universe, including the physical properties of celestial objects, as well as their interactions and behavior.

What are the sub-disciplines of atmospheric science?

There are numerous sub-disciplines, reflecting diverse areas of specialization: Atmospheric chemists investigate the chemical processes occurring in the atmosphere, such as the relationship between CFCs and ozone. Atmospheric physicists study the effect of terrestrial, atmospheric, and space-based forces on the behavior of the atmosphere.

What are the subdisciplines of Theoretical Astrophysics?

The subdisciplines of theoretical astrophysics are: Compact objects – this subdiscipline studies very dense matter in white dwarfs and neutron stars and their effects on environments including accretion. Physical cosmology – origin and evolution of the universe as a whole.
