planetary science to astrophysics. Cosmology and astrobiology are also forms of astronomy, all of which gets to the most important point to remember, especially in the context of a comparison with astrology: Astronomy is a scientific discipline, based on research, observation, and the scientific met...

They study the properties, motions, and behaviors of stars, galaxies, planets, and other celestial bodies. Observational astronomers often work with large astronomical surveys and use advanced imaging and spectroscopic techniques to gather data.

You would use scientific notation when working with large or small numbers that can be unwieldy to write out in standard decimal form. For instance, in astronomy, distances between celestial bodies are often expressed in astronomical units (AU), and these distances can involve a lot of zeros. ...
”Syzygy” is the astronomical term for when three or more celestial bodies (such as the Sun, the Moon, and Earth) line up. When the Sun, Earth, and Moon form a syzygy, we experience a full or new Moon, depending on whether the Moon is between the Sun and Earth or Earth is betwee...
