The Star Spot

Feature Guest: Nico Hamaus

Astronomers are no longer avoiding the void. Between the overdense zones of our universe, where most galaxies live, there exist vast regions of near emptiness that can stretch for hundreds of millions of light years. But these voids are not nearly as inconsequential as you might imagine and now they are finally getting the attention they deserve. Astronomers are peering into the void in the hopes of solving a variety of cosmic mysteries, from gleaning critical insights into dark matter to studying unique galaxies found in the voids. Today we’re joined at The Star Spot by Nico Hamaus as we study the spaces between.

Just as we're learning more about our solar system's own Kuiper Belt, we're also discovering that extrasolar systems may harbour similar structures. Dave helps us understand just where such disks may originate. And while it may be just a little world, Anuj tells us dwarf planet Pluto has a surprisingly complex inner (and surface) life.
