methane on Mars
Astrophysics and Astronomy | Physics
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!
Three-way Alien Sex
While you humans struggle to find a way to make three people do a job meant for two, three-way alien sex is a biological necessity for our alien procreation. If you think it's a challenge to get two in the right mood at the same time, try it with three. For you, the three-body-problem may be a surprisingly complicated calculation in Newtonian orbital mechanics, but for us it's a matter of the survival of the species.
