The Ultimate Astronomy Reviewer

Last Updated on 03/24/2021 by FilipiKnow

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.

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.

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.
