This blog is dedicated to all those who love astronomy .................(not astrology)

What is astronomy?

Dictionary defines Astronomy as “the study of objects and matter outside the earth's atmosphere and of their physical and chemical properties.” Truthfully, though, you could say that astronomy is the study of everything, because everything is a part of the Universe. 

Fields within astronomy

There are many fields within Astronomy. Cosmologists study the Universe as a whole, including its beginnings. Astrometrists measure great distances. Planetologists study planets within our own Solar System as well as those orbiting distant stars. Radio Astronomers use radio-telescopes to study the Universe. There are also Mathematical Astronomers who use numbers, calculations and statistics to explain the universe.

Astronomy is not a “stand-alone” science. It combines areas from a number of other fields, including mathematics, chemistry, geology, biology and physics. In fact, physics is such an integral part of the field that many astronomers are also known as Astrophysicists.

Why should we study the Universe? 

As we said earlier, everything is part of the Universe, and that includes us. That's right. You are part of the Universe, everything is. We live on a planet, Earth. The Earth circles the Sun, which is a star called Sol, and just like all the other stars it is part of Outer Space. Hopefully, as you learn more about the subject, you’ll appreciate just how much astronomy has affected and continues to affect your life.
