History Of Space Exploration: How Ancient Astronomy Worked?

Ancient humans looked at the sky, recognizing patterns among stars and naming them after their favorite gods and heroes. Greeks and Indians went some step further to say that there were numerous other worlds. It is not clear if any of them ever thought that we could even travel to those far worlds but our curiosity to know about them and to learn the effects of their presence on us and our world, has been going on since centuries. Telescopes were invented later in the 17th century but our imaginations had reached the end of the universe even before.

Space is a generic term we use for all other things outside the earth. Astronomically we have fixed a line for it, known as the Karman line, above which whatever lies is called to be in “Space”. Let’s see the history of space exploration and some important events.
