People often think that the age of space exploration began with the first spaceships in the 1950’s and 1960’s, though in fact, astronomers had been exploring the universe long before the beginning of space flights. Galileo made the first optical telescope used for astronomy in 1609. Later scientists got a lot more information about the solar system and its planets with the help of interplanetary probes, space capsules that carry special equipment and send information back to Earth.
