A great part of the astronomy comes from star charts, astronomers use them to identify certain images, such as stars or galaxies, in the night sky. The first star chart discovered was in 1939, in Germany. Even though it wasn't a real chart, it eventually was a carved ivory mammoth tusk. Eventually also we have the possibility ourselves to create star charts, without even needing to get out of our home. Since the internet offers us the possibility to look at the night sky.
