The latest issue of Sky & Telescope (Feb 2015), author Marcus Woo walks readers through the science of . . . nothing. Featuring research of postdoc Paul Sutter and his work on cosmic voids.

"Empty space makes up most of the universe by volume, and though most astronomers are drawn to light, it's in these blackest of voids where we can potentially learn the most about dark energy, dark matter, and the growth of galaxies."
