Standardisation of Astronomy (Author : Nipun Singh)

-
Astronomy has been observed in different parts of world for many centuries. Every region has their own way of calling these celestial bodies. But to know more about space people must share information. That is where the standardized system came into play.

Standard Names of Stars and Constellation 

Johann Bayer, considered an amateur astronomer, was the first to use the system of naming of stars, that is considered standard now.


The greek letters given to star in constellations is based on their order of brightness. Alpha for brightest and Omega for dimmest star.

This picture shows the different universally accepted constellation names, with their brightest stars.

These nomenclature are good but, how these became universally accepted. 

Formation of IAU
In 1919, the world came together to safeguard and promote the science of astronomy and founded International Astronomical Union. This began the universalization of astronomical terms.


Any celestial body when observed for the first time is given a particular name. What would happen if the names are based on public suggestions.

This shows that having scientific naming is better than following common knowledge. And thus, a standardized system for naming is necessary for the development of astronomy.

join us on our journey to the final frontier Our  solar system  is a vast and fascinating place, filled with a wide variety of celestial objects beyond just the planets. In this blog post, we will explore some of the most fascinating objects in our solar system, including asteroids, comets, and more .   Asteroids: The Building Blocks of Planets Asteroids  are small, rocky bodies that orbit the sun. They range in size from just a few meters to several hundred kilometers in diameter. The largest asteroid in our solar system is Ceres, which is also classified as a dwarf planet.              Pictures of exceptional asteroids One of the most interesting things about asteroids is that they contain a wealth of information about the early history of our solar system. Scientists study asteroids to learn more about the formation and evolution of the planets, as well as to better understand the potential risks of asteroid impacts on Eart...
