Bright Ring Around Star Fomalhaut
On the left is the visible light observation of the star Fomalhaut by the Hubble Space telescope, while on the right is the new view by the Atacama Large Millimeter/submillimeter Array (ALMA). ALMA has only observed part of the ring thus far. These images will help astronomers understand the formation and evolution of planetary systems.
