Everything and anything on Earth is part of the Universe, a vast expanse filled with planets, stars, moons, comets, galaxies, black holes, and other celestial bodies we have yet to discover.
Our Earth is just a speck of dust in one galaxy out of the billions of galaxies in the universe. Nevertheless, human curiosity knows no bounds. So to better understand our place in this Universe, we turn to astronomy, the study of celestial objects and phenomena in space.
In this reviewer, we will be delving into the origins of the universe, how different celestial bodies are formed, and how they interact with one another.

1. A Brief History of Astronomy
Let’s look back on some of the most notable personalities and principles that have shaped the field of astronomy into what it is today. Click here to go to the article.
2. The Origin of the Universe and the Solar System
Cosmology is the study of the origin and evolution of the universe. In this article, we’ll focus on the basics of cosmology to explore the two theories that explain how our universe–and the solar system–formed billions of years ago. Click here to go to the article.
3. The Solar System and its Planets
Our Solar System is part of the Milky Way Galaxy. According to NASA, it currently consists of the Sun, 8 planets, 5 dwarf planets, and more than 200 moons. Let’s discuss all these celestial bodies one by one. Click here to go to the article.
4. How the Earth Was Formed
Earth didn’t appear out of nowhere. In this article, learn the scientific explanation behind how the planet Earth–and all of its life-sustaining elements–formed billions of years ago. Click here to go to the article.
5. The Motions of the Earth
The Earth goes through three types of motions: rotation, revolution, and precession. Let’s review them one by one. Click here to go to the article.
6. The Motions of the Moon
Just like the Earth, its moon also makes predictable movements that affect both our planet and all its inhabitants. Case in point: Solar eclipse occurs when the moon comes between the Sun and the Earth. Click here to go to the article.
7. Other Celestial Bodies in Space
Given the vastness of the universe, it is no surprise to find that we have other celestial neighbors aside from other planets. Learn fascinating facts about stars, comets, asteroids, galaxies, and blackholes. Click here to go to the article.
