As the world developed new technology, astronomers discovered more celestial bodies, such as asteroids and black holes and such. Galaxies were probably discovered long ago before these modern telescopes came along. Even with the lack of technology, someone has discovered about the galaxies. Who and how did he/she find out about the galaxies' existance?
