Walkabout the Galaxy
Astrophysics and Astronomy | Physics
We love antimatter, and we love the matter-antimatter paradox. How come there was just a smidge more matter in the universe than antimatter? Neutrinos, the wispiest of particles, may provide a clue. We also check in on another Earth-like exoplanet, and Jim tackles a sexy stumper, plus space news, astronomy trivia, and more with your friendly neighborhood astroquarks.
Are you a moon who's feeling locked into a tidally synchronized spin and orbit? Wish you could just once turn your back on that smug planet you've been circling for billions of years? Libration may not be able to offer you liberation from your gravitational bind, but libration can almost set you free. All you need is a bit of orbital eccentricity to let you race ahead or hang back so you can thumb your nose at that stuck up planet, or at least have your nose not pointing right at it for a bit. So crack out some libations, and celebrate your synchronous rotational liberation with libration. Libration, a little dab will do you.
