Episode 89: Extremely Emotional Exoplanets
Tuesday Apr 16, 2024
Tuesday Apr 16, 2024
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!

Episode 88: The Luck of the Irish
Saturday Mar 30, 2024
Saturday Mar 30, 2024
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.

Episode 87.5: The Shamrock Shake-Up
Sunday Mar 17, 2024
Sunday Mar 17, 2024
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!

Episode 87: Unexpected Gravitational Waves
Sunday Mar 10, 2024
Sunday Mar 10, 2024
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.

Episode 86: Indigenous Astronomy Part II - Science of the First Astronomers
Friday Feb 23, 2024
Friday Feb 23, 2024
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!

Episode 84: Abominable Ice
Sunday Dec 10, 2023
Sunday Dec 10, 2023
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.

Episode 83: Stellar Shrinkflation
Monday Nov 27, 2023
Monday Nov 27, 2023
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.

Episode 82: So the universe thinks it can dance?
Saturday Nov 11, 2023
Saturday Nov 11, 2023
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.
