Astronomy -

Modern astronomy is typically divided into two main approaches, often overlapping with several specialized subfields:

Focuses on the direct study of celestial objects using tools like telescopes and satellites to collect data from electromagnetic radiation (light, radio waves, X-rays). astronomy

Uses physics and mathematics to create computer models and hypotheses that explain how celestial systems work and evolve. Modern astronomy is typically divided into two main

The search for and study of the potential for life beyond Earth by examining exoplanets and extreme environments. Basics of Astronomy: Exploring the Universe and Night Sky Basics of Astronomy: Exploring the Universe and Night

Astronomy is the natural science that studies everything beyond Earth's atmosphere, including celestial objects like stars, planets, and galaxies, as well as phenomena like supernova explosions and the expansion of the universe. It is one of the oldest scientific disciplines, evolving from ancient observations of the night sky into a highly technological modern science. Core Branches of Astronomy

The branch focused on the origin, evolution, and ultimate fate of the entire universe, including theories like the Big Bang.

The study of the physical properties and interactions of celestial bodies, such as the behavior of black holes and the lifecycle of stars.
