'Super-puff' planets lighter than candy floss discovered by international team

An international collaboration has discovered two of the lowest-density giant planets ever detected: rare "super-puff" planets with densities lower than candy floss. The study—led by the University of Oxford, in collaboration with Université Côte d'Azur/Observatoire de la Côte d'Azur and the University of Birmingham—has been published in Monthly Notices of the Royal Astronomical Society.
