The discoveries of small particulate clouds surrounding several young stellar objects may be the first direct indications of ongoing planet formation in the Galaxy. If these clouds are indeed the initial stages of new planetary systems around the stars, then planetary systems are probably not rare occurrences around stars and may even be quite common. The evidence for these clouds and their interpretation as young planetary systems is reviewed and discussed in the context of estimating the probability for planet formation around solar-mass stars.
