You’ve heard about planets, stars, galaxies, and other “types” of astronomical objects on the show — but what about the objects that defy our classification schemes? Will discusses how a mysterious system of massive planets(?) came to be, Alex puts on his thinking cap and tells us about the Universe’s biggest hat, and we top it all off with a discussion of the benefits and shortcomings of classifications in astronomy.
