The sub-disciplines of observational astronomy are as follows. Radio astronomy – the study of celestial objects at radio frequencies – above 300 µm. Submillimetre astronomy – the study of celestial objects at submillimetre wavelengths – 200 µm to 1 mm. The observations and their results are used to determine the formation and evolution of galaxies.
There are two main branches of astronomy:
Optical astronomy (the study of celestial objects in the visible band) and non-optical astronomy (the use of instruments to study objects in the radio through gamma-ray wavelengths). "Non-optical" is sorted into wavelength ranges
Such as :
Infrared astronomyGamma-ray astronomy
Radio astronomy
Astronomy
Science that encompasses the study of all extraterrestrial objects and phenomena. Since the late 19th century
astronomy has expanded to include
Astrophysics
The application of physical and chemical knowledge to an understanding of the nature of celestial objects.
There are so many types of objects that astronomers study
That it is convenient to break astronomy up into subfields of study. One area is called planetary astronomy
And researchers in this subfield focus their studies on planets
Both within and outside our solar system
As well as objects like asteroids and comets.
Enlisted below are some of the popular branches of astronomy. 1. Planetary Astronomy Planetary astronomy is the study of planets and planetary bodies, including moons, comets, and asteroids. Astronomers in this field study planetary & exoplanetary atmospheres, surfaces, and exteriors of planets and the distribution of planets around other stars.

Branch of astronomy about the celestial sphere
Spherical astronomy
Or positional astronomy
Is a branch of observational astronomy used to locate astronomical objects on the celestial sphere
As seen at a particular date
TimeAnd location on Earth.It relies on the mathematical methods of spherical trigonometry and the measurements of astrometry.
