Gaps in gas disks around stars may not always mark newborn planets
New research is prompting a debate over how to study infant planets
DISK DIVERSITY The swirling disks of gas and dust around young stars, some of which are shown here in images taken by the Atacama Large Millimeter/submillimeter Array in Chile, come in a variety of forms. New research raises questions about whether gaps in the disks mark the birthplaces of planets.
