Astronomy 101

Study Notes

Astronomy is the empirical and theoretical investigation of celestial phenomena.
It encompasses the study of astral bodies, including stars, planets, and galaxies, as well as the macrocosm as a whole.
Astronomy scrutinizes the attributes, genesis, and evolution of celestial entities, and the physical laws that orchestrate their motion and interplay.

Astronomy offers a unique perspective on the universe, allowing us to unravel its mysteries and expand our understanding of the cosmos.
Studying astronomy fosters critical thinking, problem-solving skills, and a sense of wonder and curiosity about the world around us.
It contributes to technological advancements and innovations in fields such as space exploration, telecommunications, and imaging technology.

The first ever astronomical empirical observations date back 5000 years to the Mesopotamian civilization.
Galileo Galilei, a pioneer in astronomy, made the first telescope and discovered the four largest moons of Jupiter, later named the 4 Galilean moons.
Claudius Ptolemy, a Greco-Egyptian astronomer, is often regarded as the "father of astronomy" and authored the influential work "Almagest", which synthesized Greek and Babylonian astronomical knowledge and proposed the geocentric model of the universe.
Nicolaus Copernicus, a Polish astronomer, is famous for presenting the widely accepted heliocentric model, where the Sun is at the center and all other planets orbit around it.
