Astronomers had long assumed that there were planets orbiting stars other than our Sun, but it is only since the 1990s that we obtained evidence that this was true. Now we know of thousands of these planets, making it clear to us that planetary systems are common. However, except in a few special cases, we have never seen any of them. The speaker will explain the various methods that are used to detect them and to discover a good deal of information about their orbits and characteristics.
