Blog Post Image: ‘Nuisance’ Data Lead to Surprising Star-Birth Discovery

This artist’s impression depicts one of the SPT-discovered light sources based on observations by Atacama Large Millimeter Array and the Hubble Space Telescope. The massive central galaxy (in blue, seen by the Hubble telescope) bends the light of a more distant, submillimeter-bright galaxy, forming a ring-like image of the background galaxy that is observed by ALMA (red).
