🔭 Astronomy: The Science of the Universe and Space

Astronomy is one of the oldest sciences known to humanity. It is the study of celestial objects such as stars, planets, galaxies, comets, and all phenomena that occur beyond Earth’s atmosphere. Since ancient times, humans have observed the sky out of curiosity, and with modern technology, astronomy has developed into a precise science using telescopes, satellites, and space probes.

🌌 What Is Astronomy?

Astronomy is the science that studies:

• The universe and its structure

• Celestial bodies and their motion

• The formation of stars and galaxies

• Cosmic phenomena such as black holes and supernovae

It relies heavily on physics and mathematics to understand how the universe works and how it evolves over time.

🪐 Main Objects Studied in Astronomy

🌍 Planets

Bodies that orbit stars. In our solar system, each planet has unique characteristics and atmospheres.

⭐ Stars

Huge spheres of hot gas that produce light and energy through nuclear fusion. The Sun is the closest star to Earth.

🌠 Comets and Asteroids

Rocky or icy objects that travel through space. Some occasionally pass near Earth.

🌌 Galaxies

Massive systems containing billions of stars, gas, and dust. Our galaxy is called the Milky Way.

🕳️ Black Holes

Regions with extremely strong gravity where not even light can escape.
