Chef Shuai Wang was the runner-up on the 22nd season of Bravo’s Top Chef and is the force behind two standout restaurants in Charleston, South Carolina—Jackrabbit Filly and King BBQ—where he brings together the flavors of his childhood in Beijing and the spirit of the South in some pretty unforgettable ways. He grew up just a short walk from Tiananmen Square, in a tiny home with no electricity or running water, where his grandmother often cooked over charcoal. Later, in Queens, New York, his mom taught herself to cook—her first dishes were a little salty, but they were always made with love. And somewhere along the way, Shuai learned that cooking wasn’t just about food—it was about taking care of people. After years working in New York kitchens, he made his way to Charleston and started building something that feels entirely his own. Today, we’re talking about how all those experiences come together on the plate, the family stories behind his cooking, and what it’s been like to share that journey on national TV.

Apply to join us as a co-host! https://astrosoundbites.com/recruiting-2025 This week, Lucia, Cole and Cormac discuss cosmic sandwich kids: intermediate mass black holes. Where are they hiding? How do they form? And can they grow up to become supermassive black holes? To answer questions like these, we take a look at globular cluster simulations and a famous gravitational wave event: GW190521. The discussion takes us to alien civilisations in the far, far future.

The more things change, the more they, uh, change. This episode Cole, Shashank, and Cormac cover the exciting events that change what we see on the night sky. Ancient astronomers tracked the motions of the planets and the arrival of “guest stars” (supernovae), and nowadays we’re lucky enough to see some really wild and energetic events. Cormac gives us a view into what happens when a star punches through a black hole’s accretion disc, Shashank shows us a particularly persnickety pulsar, and Cole gets his twenty minute monologue on modern classical music cut for time.

In this episode, we say goodbye to one of our beloved hosts, Sabrina Berger. We take a voyage through the depths and breadths of Sabrina’s research experience. Cole tells us how Sabrina investigates JWST’s ability to estimate the masses of galaxies through the glare of their quasars, and Lucia tells us how Sabrina used navigation satellites to calibrate radio telescopes. In between, we quiz Sabrina on her own ASB episodes and finish with Sabrina’s experience in 3 different countries and Sabrina’s advice for future grad students!

In today’s episode, Cormac, Cole and Lucia catch you up with all things Citizen Science. In the epoch of ChatGPT, Grok and Gemini (no, not the telescope), it’s easy to forget about the 20 Watt computer you’re using to read this sentence. Yes, even YOU can contribute to cutting-edge astronomical research, as we present two examples of cosmic crowdfunding in action. Cole convinces us that nearby galaxies need some Clump Scouts, and Lucia shows us how volunteers have been the (tur)key to finding a new star-studded dwarf galaxy. We also discuss the non-research benefits of democratising science, and in a fourth-wall-shattering pivot, we ask you, yes YOU, what you’d like to hear more of on a[s]b. astrosoundbites@gmail.com Astrobites: https://astrobites.org/2024/07/29/galaxy-zoo-clump-scout/ https://astrobites.org/2023/11/18/a-lonely-little-galaxy-at-the-edge-of-our-neighborhood/ Space Sound: Adapted from https://www.youtube.com/watch?v=X6vbST9iMOU XKCD Comic: https://xkcd.com/1425/ Article about the (not so?) amateur astronomer: https://astro.arizona.edu/news/tucson-doctor-wins-national-award-his-second-act-amateur-astronomer…
That stars die will be old news for most listeners. But sometimes, stars don’t just die, they get ripped apart by supermassive black holes. Cormac, Cole and Lucia discuss these so-called tidal disruption events. Specifically, how these events are connected to X-ray absorption features called extreme coronal lines. The hosts also take a look at one of the true superstars of supernova remnants: the Crab Nebula. As it turns out, studying the ejecta can give clues about the pulsar at the heart of the nebula. The discussion revolves around the every-day of doing science. Spoiler: it’s not all like solving exercise sheets.

Shoot, someone made the mistake of letting Cole pick the episode topic. In this episode, Cole, Cormac, and Shashank talk about the big boy on cosmology campus: Lambda CDM. This model has gotten a bit too big for its britches we think: what are the things about the universe that this model can’t explain? Shashank gives us a tour through the dark matter hearts of galaxies which don’t match up with cosmological predictions and Cormac shows us how 1500 (ish? We’re not clear on this one.) supernovae could hint at a fundamental flaw in Lambda CDM.

In this episode, Cormac, Lucia and Cole lift the lid on the lifecycle of space missions by peering into a preponderance of proposals. If you’ve ever wondered how your favourite telescope, rover or probe made it into space, then wonder no more. Lucia brings us a novel way to track potentially hazardous space junk using 5G, while Cole teases us with some magnetic results from the LISA Pathfinder mission. We also discuss our favourite proposed space missions, and debate the right balance between risk and reward.

Episode 101: Weather Woes In this episode, we take a dive into weather phenomena in space. Shashank, Cormac and Lucia discuss what the terms hot and cold mean in space and the temperature ranges we tend to see outside the Solar System and the galaxy. Then, Cormac tells us about the climate on Venus, and Lucia delves into cold fronts between galaxies. Finally, we round off with some hot takes about the most underrated parts of the electromagnetic spectrum in astrophysics!

Astrobites turns 100! For our ten squared-th episode we take a tour of all of the extremes of astrophysics: the heaviest and the lightest, the fastest and the slowest, the brightest and dimmest. In doing so, Shashank covers an astrobite on itty bitty particles that pack a big punch, Lucia talks about medium-ish galaxies and their black hole hearts, and Cormac panics about the danger of violent kilonovae. To help us celebrate, we meet up with some old friends to discuss dark matter, exoplanets, and how ridiculously long a Ph.D. takes.

Danger - explosive! This week’s episode is all about supernovae. These star-ripping, neutrino spewing explosions are important to various fields of astrophysics. Cormac, Cole, and Lucia discuss just when stars actually go supernova. And also, whether we can use gravitational waves to tell which compact object is left behind. Everybody gets to share their favourite supernova science and (as we all love to do) to complain about how much astronomers love old, inconsistent nomenclature. Enjoy!

In this episode, Cormac, Shashank and Cole dig deep into Galactic Archaeology as we look into the past of our Milky Way. Cole brings us a catastrophic computational collision, while Shashank gives us the low-down on low-metallicity, and we see just how the (Gaia) sausage gets made. We also discuss the rights, wrongs and funnies of Astronomers trying to name things, and the diverse design philosophies behind some of our favourite observational facilities.

In this episode, Shashank, Cole and Lucia bend time in their debut podcast together as we talk about the various ways astronomy is like time travel. Lucia gives us a peek into the past with the storied supernova Cas A, while Cole brings us on a nostalgic quest into gravitational wave memory. We hope you enjoy time traveling with us!

This episode marks Kiersten’s last astro[sound]bites episode (and also side note – we’re posting this on her birthday!). To recognize Kiersten for her incredible time as a co-host, we take a journey through her academic paper trail by discussing her papers on how magma and metallicities affect how we think about exoplanetary formation and observations. Then we take a deep dive into Kiersten’s time as a co-host and graduate student including her stance on “publish or perish” and what she’s most excited about starting her NASA Sagan Postdoctoral Fellowship this fall. Kiersten’s Papers: https://arxiv.org/pdf/2307.13726 https://arxiv.org/pdf/2407.13821…
In this week’s episode, Cormac has somehow made it to hosting a second time (applause). This time, we discuss the smallest, reddest and exoplanetiest(?) stars - M dwarfs! Find out why we call them that, and why these temperamental ‘tars are interesting for exoplanets. Sabrina tells us about not-so-boring M stars showing complex and periodic behaviour, and Will shares some *gasp* lab work-based results showing that M dwarfs may be more habitable than we think… This week’s episode rounds off with a discussion about what the “Search for Life” really means, and how it’s (sometimes mis)used in astronomy.

This week, our astro[sound]bites co-host crew starts a dance crew with the help of Kiersten, a former professional ballerina. We get a sample of Kiersten’s ballet skills through her astrobite, which tells us all about the secret spinning life of black holes. Our space sound sounds like something only those black holes could dance to! Cormac takes us through our first ever physics education astrobite on viewing solar eclipses with a disco ball. Do not fret if our dancing analogy still did not get you to put on your tap shoes as we also discuss the importance and diversity of analogies within astronomy and the podcast.

In this week’s episode, Cormac makes his hosting debut as we talk about the most pressing threat to modern Astronomy (other than a worldwide coffee shortage) – megaconstellations! Despite sharing a majority of syllables with the collective noun of asterisms we all know and pretend to remember, these formations of hundreds of satellites are becoming more and more of an issue for astronomers. Will tells us about how satellites are sprinkling spectra with a side of the Sun and Kiersten reveals how even the Hubble Space Telescope is not safe from the multi-headed monsters of Musk et al. Join us as we find out that things might not be as bad as they seem, and discuss the pros and cons of these developments.

In this week’s episode, we meet some of the animals in the neutron star zoo through astrobites with two surprising observations. Will tells us about a mysterious signal from a magnetar that appeared two years ago for 20 minutes and has yet to come back. Meanwhile, Cormac provides Will’s magnetar with some hope by telling us the story of a pulsar signal that appeared 20 years ago and just reappeared recently. Come along for a boomerang of a journey as we discuss observing pulsars from Earth, what it’s like at the pulsars themselves, and all the way back to Earth for a discussion of bad naming and bad programming languages.

Spooky season is here! In this episode, we’re investigating the ghostly disappearances of astrophysical objects. Sabrina does some detective work to solve the mystery of a missing black hole, and Kiersten tries to convince her that Halloween is the best holiday. Meanwhile, Cormac convenes with ghosts of stars to figure out where they have vanished off to. It turns out that gravitational waves are the perfect medium for an astrophysical seance!

In this episode, we learn that Sabrina misses SOFIA, brown dwarfs have sandy clouds, and Will knows a thing or two about Picaso (yes, that’s with one “s”). AND as a tribute to Black Space Week, following up from Episode 76, the papers we presented in this episode were both written by Black astronomers.

Did you know that talking about astronomy can actually make you hungry? In this episode, Kiersten and Will take us on a culinary adventure through food themed astrobites. Instead of starting with the main course, Will takes us to Mars for dessert where we dine on a meteorite that initially got confused for a huge piece of chocolate. Then, Kiersten takes us to a stellar cooking class where we learn about the ingredients needed to make small exoplanets and its striking similarities to baking a cake.

Now that Alex is a *doctor*, he’s taking his machine learning and supernova expertise to MIT and Harvard.

We’re planning a prison break! But first, we’re consulting the experts on this topic. Sabrina takes us to a distant galaxy cluster to figure out how so much light is escaping. Once we know how it’s breaking free, Will brings us back a little closer to home where he consults with the Trojans (and we don’t mean the ones from Homer’s Odyssey) about how a fraction of their fellow soldiers made a successful getaway. As Kiersten comes along for the ride, she makes the terrible mistake of mentioning the dreaded space sound by name. Will we successfully escape?

Kiersten checks the prescription of a neural network in finding strong lenses, and compares the results to those found by the original signers of the Declaration of Independence (there were 56, not 55, but Will gets his facts from National Treasure). Will takes us to the bleeding edge of the early Universe to a tiny protocluster lensed by JWST. Alex can’t decide on a final space sound so he chooses a black hole, a giant star, an X-ray transient, a quasar, AND a nova, all wrapped into one.

Today we say halo from a bird’s eye view of the Universe by exploring some of the largest simulations that exist. Kiersten tells us how cosmological simulations help us study the black hole populations that the next generation of gravitational wave detectors will discover. We also say our first goodbye to Alex as he presents his last astrobite (but don’t worry, he’ll still be around for a few more episodes!). He teaches us that most astrophysicists do not have an aversion to genetically modified organisms, especially when those GMOs are dark matter halos in the early universe. Want to join the team?

Who knew a decade would fly by so quickly? In the dramatic conclusion of our two-part series, we explore cosmology, supernovae, and galaxy evolution in the year 2033 (or 2034, if you ask Kiersten about Dragonfly). Alex tells us how massive stars might live out their final days (after a few too many disclaimers), and Sabrina portmanteaus her way through the early universe with a baby quasar in tow. We get eight futuristic forecasts from colleagues near and far (and none of them are Australian), and then we throw out our wildest predictions to tie it all together. Do you think we’ll see a Galactic supernova soon? Will we discover life on Mars, Titan, or in the surface chemistry of some distant exoplanet? Or will a solar storm fry all our tech before we get there? Let us know by tweeting at us @astrosoundbites. We can’t wait to discuss.

In this week's episode, we take you on a two-part journey to Europe! First, Lucia and Cormac guide you through the differences of graduate programs in Europe and the US. Then, we jump into a series of mini-interviews with fellow PhD students about their research. We journey through a wide range of topics, including black holes big and smalls, the powerful winds of massive stars, and much more. If you would like to learn more about any of these topics, check out the links below! The mini-interviews were conducted as part of the IMPRS-Astro Hackathon, an unconference organised by Cormac and a few colleges, which brought together students from Heidelberg and Munich.

Was the floor in your childhood home ever lava? If so, you may have been training to visit these spicy magma-filled exoplanets! In this episode, we're turning up the heat and investigating what makes magma/lava so important for potential extraterrestrial life. Sabrina takes us to the poster child of strange lava worlds and finally gives exoplanteers an answer to the long debate of whether it has an atmosphere or if its star blew it away. Then, Cormac tells us all about how water can play well with magma. Kiersten is convinced that these lava worlds might just be the perfect place for a hot summer vacation.

In this week’s episode, we take a look at the hottest trend in dark matter candidates - Primordial Black Holes. They’re like black holes, only smaller (in some cases)! Join us as we see what all the fuss is about. Kiersten shares a story of a black hole playing video games inside a star and glitching out of the mainframe, while Shashank makes his a[s]b debut with an explosive transient conundrum that *might* explain the mystery of dark matter once and for all. We round off with a discussion about our favourite pet dark matter theories and the merits of direct experimental searches.

We've reached a pivotal moment for astro[sound]bites: the podcast era where each of the original co-hosts has been replaced. Just like the Ship of Theseus , we ask: Is astro[sound]bites still the same show, even though all its original components have been replaced? We believe it is, and we’re excited about its continued evolution. In this episode, we’re thrilled to introduce the three new astro[sound]bites co-hosts: Shashank, Cole, and Lucia. They'll be joining us in the next few months, and we’ll discuss what each is excited about for the future of the show. Stay tuned for an exciting new chapter as the new co-hosts take over steering the ship!…
Episode 92: Beyond- Astronomy is a little Mental Astronomy is hard! And in ways that extend far beyond the science we do every day. In this Beyond episode, Kiersten and Cormac talk all about mental health in astronomy and the structural issues that may be contributing to things like burnout and anxiety. It’s not all doom and gloom though. There are a few things that studies suggest that can help. We also chat about strategies that have helped us when we were struggling in hopes that they may be useful to you too. We round off with Cormac’s Hai-cool poetic riff for our one sentence summary.

How fast is the universe expanding? It turns out this important value, the Hubble constant (H0), is under constant debate. The two main teams have numbers that disagree by over 5 standard deviations! Today on a[s]b, we resolve the Hubble tension once and for all, as Cormac and Kiersten square off in the Great H0 Debate. Cormac comes in with feist and facts while Kiersten engages with rebuttal and reason. In the end, there can only be 1 winner, and that’s for you to decide!

In this episode, we hear about Kiersten and Will’s epic adventures in both hemispheres! Both Kiersten and Will watched the eclipse that passed through North America on April 8, 2024 and are still buzzing with excitement. Kiersten tells us about a recent paper that explores why planets might act so indecisive about sitting between being a super-Earth or mini-Neptune. Will’s astrobite describes a similarly chaotic exoplanetary tale about a very slow moving planet which “came in like a wrecking ball” and “never hit habitability so hard” (everything in quotations must be sung in Miley Cyrus’ singing voice). All in all, we all share a laugh and an emotionally charged episode!

In celebration of the a-bit-over-a-week after St. Patrick’s (definitely not Patty’s) Day, we bring you another Ireland-related episode. Due to historically unsupported stereotypes about the Irish being lucky, we bring you two astrobites busting with cosmic coincidences and a dash of luck. Kiersten tells about a plucky planet that avoided a hangry host star, while Will brings us yet another binary black hole bonanza. Cormac shares a bit of an infamous Irish space sound that you could call cosmic comic relief. In the spirit of luck, we talk about the role of luck in our own journeys to space and in the field of astronomy as a whole.

In celebration of St. Patrick’s (not Patty’s) Day, we share a super short sneak peek at next week’s episode, featuring fun Irish astronomical facts. We’re calling it the Shamrock Shake-up! In addition to the astronomical facts, Will takes us on a journey to the past with some wild Irish lore of his own! We hope you enjoy what might be our first “Beyond the beyond” episode, and Lá Fhéile Pádraig faoi mhaise daoibh go léir!

We talk about gravitational waves again, but this time, in ways you wouldn’t expect. Cormac tells us how you could use gravitational waves to study the interior of the Sun, if the alignment is just right. Sabrina explores whether gravitational waves could be detected by Earth’s magnetosphere through the Gertsenshtein effect. Simultaneously, we learn that Sabrina knows how to pronounce Russian names properly and Will isn’t the biggest fan of theory.

In the second episode of the astro[sound]bites series focusing on Indigenous astronomy, we interview Duane Hamacher, a physics professor at the University of Melbourne and a world leading researcher in Indigenous astronomy. Duane shares his journey from Missouri to pursuing a PhD in Australia and immersing himself in the study of astronomy within the Torres Strait community, learning from Indigenous knowledge holders. He tells us how Indigenous peoples around the world have seen astronomy more as a way of life that’s embedded in their culture. Through our discussion, we challenge common misconceptions and gain insight into the profound significance that Indigenous astronomy has held for humanity, long preceding the invention of telescopes. However, our interview only scratches the surface of the field of Indigenous astronomy. Thank you to Prof. Duane Hamacher for taking the time to be interviewed for this episode! (Also sorry for the construction noise in the background of this episode! We hope the exciting interview makes up for it.) Duanes’ book The First Astronomers: https://www.thefirstastronomers.com/…

Did you know that Indigenous communities around the world have been doing astronomy since ancient times? Indigenous peoples studied the night sky with great precision. In this episode, we talk to five indigenous astronomers from across the world to understand how their identity and communities shaped their journey to science. Their interviews tell us about their cultures from who their Elders are to how they used the constellations to harvest emu eggs. Thank you to Kirsten Banks , Krystal de Napoli , Hilding Nielson , Bridget Kimsey , and Corey Gray for taking the time to be interviewed for this episode!

It’s all about ice, ice, baby! In this episode, Sabrina takes us on a trek to Antarctica. While we hide from Cthulhu, she tells us how the frigid observatory IceCube is using elusive neutrinos to tell us about the Milky Way. Meanwhile, our meteorologist Will does some investigation of the flavors of ice we can expect to find on some potentially habitable planets.
