When were telescopes first used?
|
The first time a telescope was used for astronomy was in 1609, by the Italian scientist Galileo Galilei. He discovered the four large moons of Jupiter, and supported Copernicus's theory that the planets move round the Sun. | | The Hubble Space Telescope's on-board computers control its cameras and send pictures back to Earth. |
