* Optical astronomy: This is the oldest type of astronomy, and it involves using telescopes to observe visible light from stars, planets, galaxies, and other objects in the sky.
* Radio astronomy: This type of astronomy uses radio telescopes to observe radio waves emitted by stars, planets, galaxies, and other objects in the sky.
* Infrared astronomy: This type of astronomy uses infrared telescopes to observe infrared radiation emitted by stars, planets, galaxies, and other objects in the sky.
* Ultraviolet astronomy: This type of astronomy uses ultraviolet telescopes to observe ultraviolet radiation emitted by stars, planets, galaxies, and other objects in the sky.
* X-ray astronomy: This type of astronomy uses X-ray telescopes to observe X-rays emitted by stars, planets, galaxies, and other objects in the sky.
* Gamma-ray astronomy: This type of astronomy uses gamma-ray telescopes to observe gamma rays emitted by stars, planets, galaxies, and other objects in the sky.
In addition to these types of astronomy, there are also many other types of astronomy that can be done from the ground, such as astrometry, photometry, spectroscopy, and polarimetry.
