This image has been taken with the Atacama Large Millimeter/Submillimeter Array (ALMA) in Chile, and shows a planet-forming, i.e., a protoplanetary disk around the young, Sun-like star TW Hydrae, about 176 light-years away from Earth. The dark, narrow gaps between the broad red rings have low dust densities. Planets that formed from agglomerating dust likely have formed the gaps. Although, alternative interpretations are suggested.
