van Dokkum discovers “fluffiest galaxies”

Fri, 05/15/2015

Pieter van Dokkum has discovered the most diffuse class of galaxies known in the universe, along with his team of international researchers.  These “fluffiest galaxies” are nearly as wide as our own Milky Way galaxy – about 60,000 light years – yet harbor only one percent as many stars. The findings, made using van Dokkum’s own Dragonfly Telephoto Array and the W.M. Keck Observatory, were recently published in the Astrophysical Journal Letters.
