Description

Scientists have been chasing methane on Mars for years. It's a slippery little molecule that doesn't stick around very long and has several biological (as well as non-biological) sources. The armada of spacecraft at Mars have conflicting measurements of the presence or absence of methane in Mars' atmosphere. Fortunately the astroquarks are here to make sense (or fun) of it. Plus, we discuss a cool new way to figure out the rate of expansion of the universe, and bonus methane trivia!
