What is Observational Astronomy? How does it work?

Observational astronomy is the practice of observing celestial objects and phenomena using instruments like telescopes and cameras.

It involves the physical observation of stars, planets, galaxies, and other astronomical objects in the sky.

Observational astronomy is used to gain knowledge about the universe, its components, and their behavior.

It is a form of science that uses mathematics, physics, and other scientific principles to explain what is observed in the sky.

By observing the sky, astronomers can learn about the composition and structure of the universe.

Examples of observational astronomy include studying the motion of stars and planets, measuring the distance to distant galaxies, and observing supernovae.

Astronomers also use observational astronomy to look for evidence of exoplanets, black holes, and other phenomena.
