Summary

Sensitive new cameras that astronomers have been pointing at young stars are yielding unprecedented views of swirling disks of dust surrounding the stars--probably the nurseries of planets like our own. A crop of new images unveiled this week shows several disks with mysterious bulges--perhaps dust-cloaked giant planets--and others with holes torn in them, apparently by the gravitation of planets. In one case--the youngest disk ever seen around a full-grown star--astronomers may be spying on the very moment of planet birth.
