s3e1: First, You Need Light

syzygy ·

2025/10/31

We're back with Season 3! For the next six episodes we're talking life in the universe, and so far we have N=1: we know there's life on Earth, but nowhere else as yet. Those are challenging statistics. In this episode Emily makes the case that to explore the possibility of life elsewhere in the cosmos, you need planets —and to have planets, you need stars. She then proceeds to whittle the number of potential life-bearing systems in our galaxy down to a scarily small number. But all is not lost, we

s2e6: Experimental Extraterrestrial Exo-Observatory

syzygy ·

2025/03/08

According to one survey, around one-third of Australians think aliens not only exist, but have actually visited Earth. That's ... a bit fraction. In this final episode of season 2, we ask how we'd even find out if life exists around other stars. Emily introduces the Habitable Worlds Observatory, an incredible new space telescope that's just in the early design phase and not due for years yet, with lots of technical and scientific holes to plug. Whether we can find life on other planets, who knows

s2e5: Exotelescope Expeditions

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

2025/01/03

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

syzygy ·

2024/12/19

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

2024/11/28

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

syzygy ·

2024/11/13

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:

A short announcement: Syzygy is now seasonal! From now on we're going to release the podcast in seasons, and we're excited to announce the imminent release of the first episode of Syzygy Season Two. Yep. Two. Season One is everything we've done so far. Trust us, it's easier this way. Season Two is all about Exo-Stuff —exo-planets, exo-moons, exo-comets ... are they a thing? Apparently, yes.

122: Syzygy Live! — The Power of Seeing It For Yourself

2024/07/19

Live from York's Festival of Ideas*, in front of an audience of ... what, had to be a few hundred thousand people, right? ... Emily and Chris discuss some awesome astronomy that you can go outside and see with your own eyes. In particular, they go deep on the incredible May 2024 aurora, and show what the 2024 total eclipse across the USA looked like, with a preview of amazing eclipses to look forward to in the coming years.

121: Dark Bubbles of Weakness

syzygy ·

2024/06/04

A huge team of astronomers— and their even-huger team of tiny, fibre-obtic-wielding robots — are zeroing in on one of the great questions of cosmology: just what the heck is going on with Dark Energy? We know the Universe is expanding. Apparently, it's expanding faster. But maybe it is expanding faster, slower? Tiny robots measuring breathtakingly-huge cosmic bubbles may give us an answer.Help us make Syzygy even better! Tell your friends and give us a review, or show your support on Patreon:

120: Biggest Small Black Hole

syzygy ·

2024/04/29

This week, a new Black Hole Record (kinda), and with it a nice conundrum. the GAIA mission has found the biggest black hole ... of the stellar-mass variety ... in our galaxy. A lot of caveats there, but the fun thing is, it's just next door, which makes us wonder if that's coincidence or a harbinger of more big black holes to come in GAIA's data dumps! Plus, a riddle: why do we keep spotting black holes that are too big to make? Did we break physics? Emily has a few explanations.Help us make Syzygy
