Astronomy

What is it?

Carefully and systematically observing the stars.

Why is it Used?

It has always been used to plot the positions of the heavenly bodies, follow their movements in the sky, and be alert for unexpected events, such as the arrival of a comet.


How is it unique?

The main difference between astronomers and most other scientists is that astronomers can only conduct direct experiments in the solar system-by sending spacecraft.

They cannot experiment on stars and galaxies.
