Exo-planets, sure. Exo-moons and -comets? Fine. But exo ... telescopes?! Emily is going out on a limb in this episode, expanding the definition of telescope to include things that measure stuff in space, and we're here for it! Which means we really do have a few telescopes out there beyond the Solar System, in the shape of Voyagers 1 and 2, with a few more waiting in the wings.On the web: syzygy.fmHelp us make Syzygy even better!

s2e4: Exoplanet Extrapolation
We know, we know — we did exoplanets last time. But that was the current state-of-play and a 2024 exoplanets wrapped update. In this episode, Emily looks to the future! She does a deep dive into the promise of the just wonderful JWST, as it prods exoplanets in ways they’ve never been prodded before.On the web: syzygy.fmHelp us make Syzygy even better!

s2e3: Exoplanets ExoWrapped
It couldn't be a season of exo-stuff without taking a good hard look at the current state of exoplanets, the OG exo-thing. Emily sums up the state of exoplanet research in 2024 — her Exoplanets 2024 Wrapped, if you like — then lines up her top three exoplanets of the year, and considers what's coming up next in this exo-ploding field.On the web: syzygy.fmHelp us make Syzygy even better!

s2e2: Exocomet Excitation
Exoplanets, sure. Exo-moons too, apparently. But exo ... comets?! Yes indeed, they're a real thing, and we've known about them for ages! How do you spot something so tiny around another star, so far away? Emily has the insider knowledge, because it's something she's genuinely investigating in her job as an actual, real-life astronomer.On the web: syzygy.fmHelp us make Syzygy even better!

s2e1: Exomoon Expectation
Way, way back in the early epochs of Syzygy (ep 19 in Oct 2018 if you must know) we talked about the exciting prospect of spotting the first exomoon — a moon orbiting a planet orbiting a star that is not our own. It seemed reasonable to expect that six years later exomoons would be a thing we've discovered, and maybe even started a catalogue. But turns out, observing a minute signal on top of an already minute signal is hard. Emily outlines our best prospects for exomoon discovery.On the web: syzygy.fmHelp us make Syzygy even better!
