ASTRONOMY:
Spying on Solar Systems in the Making
Govert Schilling
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.
