No one has yet proved that life exists on other planets. However, as there are billions of stars, some with planets, it seems unlikely that Earth is the only place with the right conditions for life. Astronomers use radio telescopes to search for messages from other civilizations. In 1963, they thought they had found the first traces of intelligent extraterrestrial life when regular pulse of radio waves were detected. In fact they had found strange distant galaxies called quasars.
