Poetry in motion: Rare polar ring galaxy captured in new image
(Phys.org)—Brian Svoboda of the University of Arizona, who recently studied the chemical and temperature environment of NGC 660, believes that unique morphology arises from a previous interaction with a gas-rich galaxy. The geometry of NGC 660—an enormous edge-on polar ring (some 40,000 light-years across)—contains more gas (and associated star formation) than its host, which strongly suggests a violent formation.Continue Reading
