We should first reference that Astrology and Astronomy are not the same things. However, they used to be heavily connected and you could claim they were the same thing for centuries. Yet we eventually separated from this to create two different fields. A lot of people are to thank for Astronomy today, especially as it began to enter the world of Astrophysics. It seems that the major change and separation happened in the late B.C. era and by the ADs, Astronomy was a huge scientific field.
That is where you see the likes of Newton, Halley, Kepler, Hubble, Hawking, and Einstein come into play. To them, anything related to space overall as well as a lot of the things having to do with the planet was connected to Astronomy. In the original meaning, Astronomy was merely the study of the stars. This clearly expanded and allowed us to see some of the most critical things related to life, how we’re here, what keeps us here, plus much much more.
