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!

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!

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!

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. So keep an eye out in the days ahead for the new season of Syzygy.Help us make Syzygy even better!

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. Chris finishes with a song, as he does. Watch on YouTube!(* Apologies for the audio quality, it was a big echo-ey space and it didn’t record as well as I’d hoped)Help us make Syzygy even better!

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!

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 even better!

We're live from the 10th birthday celebrations for the University of York's Astrocampus, Emily's home turf and all-round fabulous teaching and outreach space. Emily fields some amazing questions from kids and adults attending the event, and gives some of Astrocampus's highlights and achievements over the past decade, as well as some plans for the future!Help us make Syzygy even better!

After some lengthy follow-up (the Bennu sample is open at last! And SLIM is alive!), Emily investigates possibly the most podcasty story we’ve had on the show: six planets around distant star HD110067, all locked into resonances that play beautiful music. Turns out if you leave a planetary system alone for long enough, gravity tends to pull everything into simple harmonies. Maybe our own solar system has a song to sing in the far future?Help us make Syzygy even better!

Emily and Chris tune in to JAXA’s livestream of SLIM — the Smart Lander for Investigating and Moon — as it attempted to slick the landing on the lunar surface on Friday 19 January 2023. We were prepared for success and champagne, or failure and lessons-learned. What we didn’t expect was … ambiguity, uncertainty and WE ARE STILL CHECKING THE STATUS SO PLEASE WAIT. Did SLIM and its fabulous little transformer rovers make it to the Moon OK or not?!
