Ordinarily I would not post twice in a week about giant ducks, but this has been no ordinary week, gentle readers. As you are no doubt aware, the European Space Agency spacecraft Rosetta is heading for a rendezvous with the comet 67P/Churyumov–Gerasimenko. Recent advance imaging of said comet looks like this:
Do you see what I see? Don't worry, other people see it too. Even the BBC calls it a "space rubber duck" and if it's good enough for the beeb, it's good enough for me. The space duck formerly known as comet 67P/Churyumov–Gerasimenko is 4.5 km across, dwarfing recently cited giant ducks by orders of magnitude.
Please join me in welcoming our new space duck comet overlords.
