Searching for Messages from Alien Civilizations
We cannot travel to different solar systems, and, though many people seem to believe that UFOs are spaceships visiting from other planets, most astronomers believe that the chances of a visit from an alien are slim to none.
However, since the invention of the radio, humans have been broadcasting signals into outer space. Other civilizations in our Galaxy might be doing the same. They might even be deliberately sending out signals to find other civilizations. Someone out there may even be beaming a signal directly at the Earth.
With our current technology, the chances of us finding a signal are fairly bleak. There are currently no nationally-funded programs searching for signals from other civilizations, but the SETI Institute continues the search, using private donations.
