Space Quizzes, Questions & Answers

Not merely void and vacuum (though it is, of course, those things too), there’s a lot going on out in space that you may not be aware of.

From cosmic background radiation to hydrogen and helium plasma particles – and even the occasional interstellar research craft; Voyager 1, for example – there’s more in outer space than meets the eye. Do you know much about the Big Bang, exoplanets, or the nearest star system to our own?

Are you thrilled to pore over the theses of Henrietta Leavitt, Edwin Hubble, the late great Carl Sagan, and other famous astronomers and astrophysicists? Take our quizzes to prove your intergalactic ingenuity, and if the questions are too hard, don’t worry: in space, apparently, no one can hear you scream.
