Astronomers have found thousands of potential exoplanets and many stars with massive disks of gas and dust that suggest planets are forming, but not much of the stuff intermediate between dust and planets, such as asteroids, planetesimals and comets. Astronomers looked closely at a number of stars with dust disks and found evidence that they also have comets, suggesting that comets are a common accompaniment to planets in many stellar systems.
