Europa’s got miniature tectonic activity, and a dark matter candidate may real itself through micro-gravitational lensing events. Dr. Audrey Martin joins us to discuss the strange spectra of the Trojan asteroids which have similar characteristics to comet dust tails. Join us for all this, silly particle name trivia, Artemis updates, and more.
Spice up your life with magnons. Unlike the particles of your everyday existence, magnons are quasiparticles with all the benefits of boson behavior without the pesky detail of being an actual thing. So cool your ferromagnets and cook up a tasty gas of these quasiparticles as your electron spins become misaligned. Mention Walkabout the Galaxy when getting your magnons, and we'll throw in a collection of paramagnons at no additional charge. Visit our website, www.magnonsrus.com, and check out our full collection of delicious quasiparticles, including phonons, spinons, orbitons, and more. Orbitons, melts in your mouth, not in your hands (M&Ms).
