Episode 94: The Floor Is Lava!

astro[sound]bites ·

2024/06/30

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

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

Episode 92.5: The Ship of 3-seus

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

Beyond- Astronomy is a little Mental

2024/06/04

Episode 92: Beyond- Astronomy is a little MentalAstronomy 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

Episode 91: A Uranian FareWill

2024/05/23

91 is the atomic number of protactinium. Speaking of protracted, it’s finally time to say FareWill to Dr astroSaundbites himself, after five years of co-hosting our wonderful podcast. We begin with a deep dive into his Uranian adventures that might offer the key to our next mission there. We then reflect on his time in grad school, share some sage wisdom and explore what the future holds as he transitions to a not-postdoc at NASA. Will’s first paper:

Episode 90: The Great H0 Debate

astro[sound]bites ·

2024/04/29

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

Episode 89: Extremely Emotional Exoplanets

astro[sound]bites ·

2024/04/16

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”

Episode 88: The Luck of the Irish

2024/03/30

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

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!Intro music excerpt: “Granny hold the candle while I shave the chicken’s

Episode 87: Unexpected Gravitational Waves

2024/03/11

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

2024/02/23

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

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

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

Episode 82: So the universe thinks it can dance?

astro[sound]bites ·

2023/11/12

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

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

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
