It's amazing what we can observe in other star systems. Astronomers recently reported that they've examined belts of icy pebbles surrounding dozens of stars. They used radio telescopes to see the wavelengths of radiation emitted by millimeter-sized pebbles created by much larger exocomets smashing together. Based on this survey, they've found that about 20% of planetary systems contain these exocometary belts, in shapes that can be very different from the Solar System.
