Description

The universe began in a hot, dense state, as the song goes, and we can, oddly, see that heat from the thing that we are still in. The universe. Strange stuff. The radiation leftover form the big bang, known as the cosmic microwave background, or CMB, has cooled off, but analysis of measurements of this radiation by the Planck spacecraft point to some odd hot and cold halves of the universe. The astroquarks take a deep dive into the CMB, plus lots of new spaceflight news and of course your Walkabout trivia.
