Apart fromm sending astronauts into space, we also use satellite, probes and telescopes to study space. Like moons, man-made satellites revolves around planets and help us learn more about them. A probe is an unmnned spacecraft sent into space to study objects other than the Earth. We have even put huge telescopes into orbit. The Hubble Space telescope, sent into orbit in 1990, is the best-known among these. It is better to have a telescope in space than on Earth, because then there is no atmophere to distort the image received by the telescope. However, the biggest telescopes are too big to be sent to space.
