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.

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.

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! Vote here for the winner of the debate, what the true value of H0 should be, and what we got wrong in the episode (we tried our best!). https://forms.gle/3dybtrhysS9Lvia37

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.)

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.

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.

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.

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.

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.

Before we bid our tearful farewells to Alex, Sabrina and Kiersten present and discuss two of his three publications. We learn how Alex developed and deployed a machine learning model to classify supernovae using only photometry from their host galaxies! Now that Alex is a *doctor*, he’s taking his machine learning and supernova expertise to MIT and Harvard. During the episode, Will peppers Alex with some important and some…less than important interview questions. Together the gang explores what happens when you try to replace your friend with an AI.

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? Or will we be caught and forced to listen to space sounds forever?

In case your graduate student insurance doesn’t cover you over the summer, join us now as we take a quick trip to the optometrist! 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.

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.

What will astronomy be like in the year 2033?
In the first of this two-part series, we predict the (short-term) fate of the solar system, exoplanets, and the culture of astronomy a decade down the line. Kiersten and Will both focus on planets, one close to home and the other (hopefully) not too far away. We then get futuristic forecasts from six guest astronomers working around the world, who paint us an exciting (and slightly troubling) picture of new-wave astrophysics, covering everything from the role of machine learning to a crisis in publishing, with discoveries of Earth-like exoplanets in between!
Stay tuned for Part II, in which Alex and Sabrina will talk about the more distant universe and eight more guest astronomers describe the future of their fields.

In our second episode taking another in-depth look into community college, we start off by hearing about Sabrina’s experiences. She tells us about her journey from attending high school abroad to starting community college. Kiersten also interviews , Prof. Andria Schwortz, a physics and astronomy professor at Quinsigamond Community College. Join us on an adventure to Europe, community college, and with a second love story sprinkled in. Don’t forget to check out our associated astrobites beyond post!

Did you know that half of our astro[sound]bites co-hosts went to community college? We’re here to talk about our experiences and work towards breaking the stigma! This is our first episode in this two part series which features Kiersten’s trajectory from community college into a brilliant exoplanet scientist. Next, Alex interviews Dra. Natalie Nicole Sanchez, an NSF MPS-Ascend postdoctoral fellow at Carnegie Observatories and Caltech, whose interest in astrophysics was sparked while studying art at community college. Join us on a whirlwind tour of engineering, love affairs, and artistic endeavors - and stay tuned for an associated astrobites post!

This episode is all about magnetic fields because we couldn’t stay away from such a polarizing topic! Alex takes us on a journey to the center of a star where we find how intense its magnetic field actually is. Along the way, Kiersten brings up a blast from the past with a sonification that had its own record release. To wrap up, Sabrina tells how we can use radio waves to find an exoplanet with a magnetic field because cosmic rays and solar winds don’t sound like a pleasant time for us humans.

We’re back with more of the most important papers in our subfields. Sabrina tells us how Karl, an engineer at Bell Labs, became the father of radio astronomy and stole her heart through time and space. Kiersten couldn’t pick just one paper so she choses a review article and gives it a favorable review on our own little a[s]b revue program.
The gang really struggles on the space sound and then decides it just might be okay to peak in grad school.

Episode 63: Our Take on Landmark Papers Part I
In this week’s episode, we take a deeper look into Alex and Will’s research through two landmark papers in their field. Will pulls out a strip chart to teach us about how Neptune’s atmosphere looked in the 1960s (and why it’s still important today). Alex gives us a deeper look into explosive transients and presents a paper on supernovae from the early 1970s that reveals the power of fermi estimation and a little intuition. Meanwhile, Sabrina kicks off a conversation about the ethics of research and faces the reality of not being able to check every line of source code from the simulations she uses. See you next episode for Kiersten and Sabrina’s turn!

Halloween is in the air! Get ready for a spoooooky episode where we take a stroll through the haunted side of the Universe. Alex takes us on a trek through a graveyard to investigate the skeletons the Milky Way is hiding - and no, we’re not talking about the candy! Then Will tells us a ghost story about the old blue monsters hiding under our extragalactic beds, but don’t worry too much. He reassured us that they only eat dust.

The gang is back! In this episode, we take a trip to the largest and the smallest astronomical scales to learn about all the exciting new ways that JWST is transforming the field in its first 100 days. Sabrina zooms out to find some sparkly galaxies and catch a glimpse into the dazzling high-redshift Universe. Then Kiersten zooms into JWST’s first directly imaged exoplanet to figure out why it’s making us all so hungry. We round out the episode with an interview from York University Professor Sarah Rugheimer, who tells us all about the science to get excited about in the years to come.

We’re herded into a crowded auditorium for a press conference held by our very own Sabrina Berger. The breaking news? We’re going on break! But not just that, we’re launching our second sonification challenge! This challenge is focused on using sound for instruction, so submit a sound that teaches us about an astronomy concept in two minutes or less. Click the link below for details. To get inspired, we hear from Jendaya Wells, a music major at Lincoln University and a member of the team using sonification to explore data from the upcoming Vera Rubin Observatory! Both her and her sonifications are very bright.

We’re first joined by Paul Green and Afra Ashraf, the creators of the new sonification project Sensing the Dynamic Universe. Then Sarah Kane, a senior undergrad at the University of Pennsylvania, joins us to talk about her journey in astronomy and sonification while being legally blind. We round things out by listening to kilonovae, radio interferometers, and the atmosphere of Uranus! Is there anything we didn’t discuss?

Is it Halloween yet? This week, Alex, Kiersten, and Sabrina zoom out to stare at the spookiest voids on the most massive scales. Alex tells us how we can use baryonic acoustic oscillations, or BAOs – the astrophysical counterpart to the delicious buns – to study the shapes of these voids. Sabrina turns up the power for her space sound, and we turn on the lights while listening to Kiersten describe a chilling cold spot in the CMB.

In this episode, Sabrina teaches Will gamer lingo and the gang applies it to astronomy. Alex discusses a class of super-charged supernovae with bumpy and clumpy physics, and Sabrina shows us how to use pulsars to upgrade our data security (once we figure out how to uninstall Norton Antivirus).
Then we discuss whether objects in the universe really can be OP (overpowered) and Alex begins to question if he ever really understood the definition (spoiler: he didn’t).

Every new beginning comes from some other beginning's end. In her final episode as co-host, Malena reflects on her graduate school experience, research interests, and celebrity crushes. Will brings us Malena’s research to unlock the mysteries of planet formation through interstellar aliens, and Alex shifts the conversation and stacks together Malena’s results on the hunt for Planet 9. He also spends way too long making the space sound.

Episode 54: Dusting off the Disks
We recorded this episode a few months ago and are dusting it off today. We’re leaving a bit of dust though, because that’s what makes debris disks so exciting! Malena tells us about a disk that is both beautiful in appearance and in its scientific potential to reveal planetary dynamics. Alex tells us about a disk that might have as much water as the solar system, but unfortunately none of it is liquid (or confirmed). Will brings us a space sound that makes the episode a little more trashy.

Will describes recent findings that the Sun is a bit sleepier than its peers, Alex Illustr(is/ates) how galaxy cluster fly-bys can make an ultra-diffuse galaxy a little more chill, and Malena delivers an uncharacteristically non-thematic space sound. To top it off, we learn about the slowest song ever written (hold your applause until the end).

More importantly, we are joined by PhD student Sophia Lilleengen, who tells us about her research into stellar streams and dark matter in the Milky Way, as well as her career in astronomy so far. Malena presents research about a quirky stellar stream and wonders if it could contain the answers to everything, all of it.

Alex and Malena sit down for a gourmet meal and Will, with curved mustache and slicked hair, pours the wine. Alex enjoys his star cluster soup as he tells us about the state-of-the-art in star formation simulations. The gang then enjoys a space sound entremet (served chilled) before moving onto a main course of freshly seared planet. Malena explains how we might tell if a sun-like star has dined on a planet, and shockingly enough, we learn that these stars like to eat. Malena also tells us all about the kind of puns she’d like to make…but she doesn’t actually make them.

Ever misplace a brown dwarf? If re-tracing your astrophysical steps doesn’t help, it’s probably where you least expect to find it. In this episode, Alex and Malena bring us some brown dwarfs discovered in truly unusual locations. Alex sees the glass half full when he tells us how brown dwarfs could explain long secondary periods in red giants, solving a longstanding mystery. Malena guides us to a brown dwarf oasis in the phase space desert and manages to still talk about planets.

Do you enjoy reading and listening to science communication? Are you ready to get involved with it yourself? From chatting with friends to podcasting, blogging to writing magazine stories, the world of SciComm is more accessible and more diverse than you may have thought.
We share some personal stories about how we got started in scicomm and hear from 2 SciCommers who made the leap from being PhD students to full-time communicators. Kerry shares her experience pitching magazine articles and discusses her new job as a Communications Specialist for the American Astronomical Society. Stephanie tells us how she discovered her passion for public outreach and how it led to her dream job as the head of the social media campaign for the Vera Rubin Observatory.

This is Episode #42, so it might just contain the Answer to Life, the Universe, and Everything. Today we set our phasers to stun and dig into some astrophysics research that brings science fiction one step closer to becoming science fact! Will teaches us what it takes to become a class II civilization on the Kardashev scale, and Malena gently reminds us that we can’t stop the change, any more than we can stop the suns from setting. Plus, Alex has a space sound that’ll leave you all starry-eared.

How do we figure out the masses of astronomical objects far too large to fit on any human-made scale? In this episode, Alex tracks the paths of planets to figure out which ones are winning a gravitational game of tug-of-war, while Will describes a mysterious little galaxy that seems to be missing a key component. And, you won’t want to miss our spectacular sonification contest runner-up from Tharindu Jayasinghe, who brought to sound the most extreme heartbeat star known to date!

We’re back from vacation! We play 2 truths and a lie about what we did this summer and learn that the truth might be subjective. Alex brings a BBQ-themed Astrobite about the brightest galaxies, teaching us that “astronomical Hot DOG” is a state of being. Malena discusses how planets vacation to the outer solar system (spoiler: they never return home).
For this week’s space sound, we speak with the winner of the 2021 Sonification Competition, Misty Bentz. Listen to and view her winning sonification, Fantasy on Active Galaxies: https://astrosoundbites.com/2021/09/11/episode-40-space-summer-surprise/

Billions of years before Van Gogh put paint to canvas and immortalized them forever, the stars in the sky were nothing more than an intricate tangle of magnetic fields and swirling gas. Turn the clock back with us as we learn about the physics of these protostellar systems! Northwestern/CIERA postdoctoral associate Erin G. Cox teaches us about the polarization patterns of Class 0 and Class I systems, and Will gets all turbulated as he discovers how HII regions might drive star formation.

Tired of vacations being ruined by cloudy weather? Alex the travel agent can book your next trip to brown dwarf binary 1416B, where it’s always a balmy 2000 degrees and never cloudy. Or maybe a sojourn to a hot Jupiter is more your style? Malena the meteorologist has you covered with your 10-million year forecast: cloudy and lopsided.
In recognition of Juneteenth and the start of #BlackInAstro week, both papers featured in this episode were led by Black astronomers.

How can astronomers study something that nobody has ever seen? In this episode, we switch to the dark side to shine a light on one of the biggest questions in all of astrophysics: the nature of dark matter. Malena teaches us how dark matter helps galaxy clusters glow up, and Will takes a journey to the center of the Earth to find prehistoric prints from a big WIMP. Plus, Alex brings us our most romantic space sound yet.

In this Beyond episode, we veer off the traditional path to a PhD with three interviews from early-career astronomers who did things a little bit differently.
Tim Holt shares his transitions from zoology to teacher and, finally, to astronomer. Ashley Walker describes how perseverance helped her to realize her dream as Chicago State University’s very first astrochemistry major. Natalia Guerrero paints a story of her journey leaving a graduate program, taking a leadership role on the TESS team, and reentering academia more inspired than ever.

Planets and quenching and stars, oh my! In this finale to our four-part series on machine learning in astrophysics, the team hits the (virtual) road to hear from the experts. Our first stop is Irvine, California, where Tae Baxter teaches us that even galaxies struggle to stay active during quarantine. Next, we’re off to Porto, Portugal, where Ana Barboza uses the planetary ends to justify the k-means. We also make a pit stop for some banana-inspired techno.
