We love it any time a listener gets in touch — but the *best* is when a listener suggests a topic for an episode of the podcast. So when Zofia Szczesna got in touch (through the Syzygy website, natch) and asked about white dwarf stars, Emily put her research hat on and dug into the amazing astrophysics of these amazing little entities. In this episode she lists her three favourite things about white dwarfs: a cheeky supernova loophole, wibbly-wobbliness, and our white dwarf (or more accurately, black dwarf) future.Help us make Syzygy even better!
