If you fancy our beloved planet's history and knowledge, you would want to learn more about astronomy— and even teach it to youngsters.
If you are excited about expanding your knowledge about astronomy, you have found the right place, and we will take you aspects of astronomy without complicating the subject. If you are ready, let's get started!
What Is Astronomy?
Astronomy is best described as the science of studying the earth and every planetary body outside our atmosphere. Astronomy goes beyond the earth's atmosphere; it also includes the studies of the stars, galaxies, moons, asteroids, comets, and other celestial objects.
But that not all!
Astronomy also extends to processes like gamma-ray bursts and supernovae explosions — including the physics and chemistry behind them. Thus, making astronomy a broad endeavor!
Closely related to astronomy is cosmology, which focuses on studying the universe (its entirety) and its evolution.
Did you know that the word astronomy is traced to the Greeks? Yes, it was. It was coined from the words "Astron," which means star and "nomos" — the Greek word for law.
Astronomy isn't a new field of study. It's arguably one of the oldest sciences. The ancient people relied on their basic understanding of astronomy to navigate and determine seasons — whether to cultivate their lands or not.
Fast forward to our present-day and time; we have a better knowledge of astronomy, and technology has advanced our understanding beyond earth to out of space.
Types of Astronomy
There are two broad classification or types of astronomy — namely, observational and theoretical astronomy. The difference between the two types of astronomy is the nature of their approach and how they are sort.
Let's break that down further.
Observational astronomy uses equipment or instruments like telescopes and cameras to study the stars, galaxies, among other celestial objects. In contrast, theoretical astronomy relies on computer models and mathematics to study astronomical objects — oh! and you shouldn't confuse astronomy for astrology because they differ a lot.
What Discoveries Have Been Made in Astronomy?
Since Nicolas Copernicus, who is regarded as "the father of astronomy," picked interest in astronomy many years ago, many discoveries have been made many years after.
In astronomy, discoveries are classified into two groups.
· The bodies, and,
· The phenomena.
Let's explain briefly.
The bodies refer to the objects (astronomical, galactic, solar, and cosmic bodes) in the universe (like a planet like earth or a galaxy). On the other hand, the phenomena refer to the series of events taking place in the universe.
Speaking of the bodies, here are some examples.
· Solar bodies include the planets, asteroids, and comets.
· Galactic bodies refer to objects inside galaxies such as the stars, diffuse objects (clusters and nebulas), and compacts stars (such as black holes and whiter dwarves).
Then there are cosmic bodies, which include galaxies, superclusters, and galaxy clusters.
There is so much fun stuff to learn about astronomy, and kids would find them fascinating. You don't have to be an astronomer to stargaze; you can get yourself a telescope to peek into space and amuse yourself with the glamorous stars.
