How did our view of ourselves and our world change as a result of:
Nicolaus Copernicus’s scientific theory of a sun-centred solar system
the invention and development of the telescope, from Galileo’s 1609 telescope to the 1990 launch of the Hubble telescope
the recent discovery of planets around other stars and the possibility of life elsewhere in the Universe
the 1969 landing on the moon
the discovery of the ozone hole in 1985
the invention and launch of artificial satellites, from Sputnik in 1957 to today where thousands of satellites – including an International Space Station – orbit the earth
Or another astronomy related discovery, important to understanding our place in the universe.
