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 spen...

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...

What’s the opposite of high-energy astrophysics? In today’s episode, we recognize the unsung heroes of astronomy: the low-energy, sleepy objects that keep on chugging in spite of it all. 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 uncharact...

In this episode, the gang struggles to come up with a title (and Will manages to still get it wrong in the outro). 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 th...

How are your sunglasses like the stars, planets, and galaxies that comprise our universe? Not only do they look cool – they’re also no stranger to polarization! In today’s episode, Will describes a mysterious transient lurking within our own galaxy, while Malena shares how baby magnetic fields might have polarized the baby Universe. Alex guides us through a trashy symphony of delightful debris, sh...

Pop the champagne and blow out the candles, it’s our fiftieth episode!! To celebrate, we’ve prepared a list of fifty different paths that you can take with a degree in physics or astronomy. What’s the difference between soft money and hard money? What does Sir David Attenborough think about the moon? How do you really pronounce the word “potpourri”? Listen to this episode to have two of these ques...

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 o...

We’re kicking off the new year by spinning a record from a few months back, about all the ways that rotation teaches us about the universe. Malena describes a few energetic stars lurking around the Main Sequence, and Will keeps his opinions about MOND to himself. Alex brings us home with an orchestral sonification to rival Stravinsky’s best.    Astrobites: https://astrobites.org/2020/05/20/blue-lu...

In today’s episode, we learn all about the clues that Kevin has benevolently placed within the Universe to teach us about the graceful and multifaceted field of galaxy evolution. Alex describes how much the galaxies of today can learn from their wise, high-redshift ancestors through Lyman-alpha emission, while Will segues into the mysterious properties of one of the most nearby aged galaxies. Male...

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...

It’s time to talk radio on the radio! In this episode, we explore some of the research beaming out of the world's largest fully steerable radio dish -- the Green Bank Telescope (GBT)! We hear from Brenne Gregory, a Scientific Data Analyst at GBT, about her trek from the rolling hills of Scotland to the heart of the Allegheny Mountains. Will keeps his finger on the pulse of a pair of neutron stars,...

All speeds are relative—especially in astrophysics. In today’s episode, we learn about the timescales of different transients and explore what the fastest and slowest events can teach us. Alex describes the fastest koala in the universe, Will shares the slowest rotating lighthouse known to date, and Malena tosses in a magnetic curveball to bring us home.   Astrobites:  https://astrobites.org/2019/...

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...

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...

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 Thari...

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...

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 syste...

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 wee...

In this episode, we discuss the varied methods used to determine stellar ages.
