Difference Between Astronomy And Astrophysics. In this article, you will come to know about what is astronomy, what is astrophysics, what is the main difference between astronomy and astrophysics, and a comparison between astronomy vs astrophysics.

Both the terms astronomy and astrophysics are the field of the sciences in which we study the atmosphere beyond the Earth. There is no major difference between them, but a qualitative distinction can be made. Here, we will first understand the main difference between astronomy and astrophysics, then differentiate between them in detail.

What Is The Main Difference Between Astronomy And AStrophysics?

The main difference between astronomy and astrophysics is that the:

-Astronomy is the study of science in which scientists observe space and the surrounding objects.

-Astrophysics is the study of science in which principles of physics apply to the research of astronomy in order to interpret the results.

What Is Astronomy?

Astronomy is the study of sciences in which scientists observes space and the surrounding objects. Scientists are studying the space, universe, galaxies, planets and their moons from hundreds of years ago. This was started when Galileo invented the telescope.

The definition of astronomy according to the Oxford dictionary is:

“the branch of science which deals with celestial objects, space, and the physical universe as a whole.”

There are some facts about astronomy that you didn’t know before about space, i.e.

-Space is totally silent.
-The hottest planet of our Solar system is Venus with a temperature of 450° C.
-The cost of a spacesuit is $12,000,000.
-About one million Earth can fit inside the sun.
-The sunset on Mars appears blue in colour.
-One day on Venus is about 225 Earth days……

What Is Astrophysics?

Astrophysics is the study of the sciences in which principles of physics apply to the research of astronomy in order to interpret the results. It is concerned with the explanation that is obtained by the observations of astronomy. For example, Newton’s law of motion is very helpful in studying the celestial objects in space.

Similarly, Einstein proposed the theory of General Relativity to study the small irregularities of Mercury’s motion. His theory of general relativity revolutionized the study of physics. The new observations of astrophysics claim that 73% of the universe is composed of mysterious dark energy, 23% is made up of dark matter, and the remaining 4% is the objects and various types of matter that we are familiar with.
