Astronomy and Astrophysics Bootcamp By Spotle.ai

Whether you want to build a career in astrophysics or space or are just exploring the areas out of interest, this Spotle.ai compact course will get you started in the fascinating world of astrophysics and astronomy.

The question arises – What is the difference between Astronomy, Astrophysics and Cosmology? So, the differences are very simple. Astronomy actually measures the positions, luminosities, motions and other characteristics of any celestial object, whereas Astrophysics creates the physical theories of small to medium sized structures in the universe, remember, small to medium sized structures in the universe. Whereas, Cosmology does this for large structures, i.e., the entire universe as a whole – all, like galaxies or like other larger structures in the universe.

In our chapter 1, we will start with the basic concept of Astronomy & Astrophysics. So, first let us know what is Astrophysics. So, Astrophysics is a branch of space science that applies the laws of Physics and Chemistry to explain the birth, life and death of stars, planets, galaxies, nebulae, and other objects in the universe as well. It has two sibling sciences – Astrophysics and Cosmology. So, now let’s move to them also.

In chapter 2, we will learn about the time.

At first the question is, what is Time? So, there is a very easy and simple answer that time is what a clock measure. This is what we all know. Now, this time is actually measured based on the position of the sun. Like you all know that when the Sun is exactly at our zenith, now we have discussed about zenith in our last lesson, that approximate, that particular time is called 12 noon. So, the position of the sun actually decides the time. So, the time at any point on earth can be measured by knowing the longitude of that point, which means time changes with longitude and that is very very very important. This concept is very much important for time. So, with the change of longitude, time changes and for the change in each degree of longitude, the change in time is 4 minutes. So, based on these conceptions, we will start, we will go into some other aspects of time.
