What does it take to see the surface features of distant stars or track satellites in deep space? In this episode we sit down with Professor Michelle Creech-Ekman, Professor of Physics and Project Scientist at New Mexico Tech. From her roots in North Dakota to her pivotal work at JPL on the Keck Interferometer, Dr. Creech-Ekman shares her journey and her current groundbreaking project: the Magdalena Ridge Observatory Interferometer (MROI).

Perched 10,500 feet high in central New Mexico, the MROI is a engineering marvel. We dive deep into the tech behind this massive optical and infrared array, including:

• High-Precision Engineering: Custom Belgian-built altitude-altitude mounted telescopes and Italian "squashed" domes that can be relocated across 28 stations in just four hours.
• Extreme Resolution: How "optical trombones" in a light vacuum delay line allow the array to achieve spatial resolution down to half a milliarcsecond—roughly 90 times sharper than the angular size of Betelgeuse.
• Cutting-Edge Science: The observatory's historic milestone of reaching first fringes on July 12th, and its mission to image starspots, track expanding supernovas, and monitor objects in geosynchronous orbit.

Plus, Dr. Creech-Ekman reflects on her passion for inspiring the next generation of scientists, the importance of human spaceflight, and why maintaining a sense of wonder is vital.

Tune in for an inspiring conversation on human ingenuity, big tech, and reaching for the stars! BONUS - find out what the shape of a wire suspended between two poles is called!

As we pull up stakes on the Plains of San Augustin and wrap up our time with the Karl G. Jansky Very Large Array, let's take a quick pit stop to reflect on our journey so far and set the stage for what's coming next on the Enchanted Frequencies Mission to New Mexico.

In this interlude episode, I preview the next leg of the expedition:

• 🏔️ Magdalena Ridge Observatory Interferometer (MROI): Bleeding-edge optical and infrared astronomy at 10,600 feet.
• 📡 The Long Wavelength Array (LWA): Listening to the universe at the lowest radio frequencies from vast fields of dipole antennas.

Can a star make a cookie and searching for techno- and bio-signatures to find signs of extraterrestrial life.

What do cosmic cookies, giant space spectrometers, and artificial intelligence in deep space have in common? They're all part of the daily work of Dr. Chenoa Tremblay, project scientist with the SETI Institute, Breakthrough Listen, and the National Radio Astronomy Observatory (NRAO).

In this episode of The Star River Podcast, host Eric Loyd sits down with Dr. Tremblay to explore the cutting edge of astrochemistry and the modern search for extraterrestrial intelligence (SETI). From her unconventional journey starting out in laboratory chemistry testing dirt samples to hunting for complex molecules and technosignatures with world-class radio telescopes, Chenoa shares a mind-bending look at how we listen to the universe.

In this episode, we explore:

• Cosmic Chemistry: How stars bake the ingredients for life - and cookies!
• Physics in the Vacuum: Why atoms actually grow bigger in the near-vacuum of interstellar space.
• Technosignatures vs. Biosignatures: Why SETI is looking for cosmic "Wall-E" robots and technological waste rather than little green men.
• The Power of Radio Astronomy: How arrays like the VLA, MeerKAT, and more process massive streams of data to hunt for artificial signals.
• The Human Side of Science: Transitioning from lab tech to lead scientist, and making space science accessible to everyone.

What happens when you leave the high-stakes, "level-10 emergencies" of political campaign management to find your center among the stars? In this episode, I sit down with Corrina Jaramillo-Feldman, Senior Public Information Officer for the National Radio Astronomy Observatory (NRAO) VLA, VLBA, and ngVLA. Together, we navigate her fascinating, meandering journey from running statewide campaigns to translating the invisible, silent data sets of radio astronomy for the global public.

As I continue my Enchanted Frequencies series of episodes from New Mexico, I saved the best for last. Corrina opens up about occupying the liminal spaces of identity, the liberating power of "cheerful nihilism" under a pitch-black Santa Fe sky, and the exciting future of the Next Generation Learning Center at the VLA. It's a deep, soulful conversation about public policy, workforce development, and remembering the sacred magic of being small.

• The "Cheerful Nihilist" Perspective: Discover how a childhood solar system book and a spooky, dark house on a Santa Fe mountain shaped Corrina's unique, joyful framework for handling life's heaviest moments.
• Sneak Peek at the Future of Space Education: Learn how the upcoming Next Generation Learning Center at the VLA is going K-12, expanding into adult trades, and transforming New Mexico into a premier global hub for workforce development.
• A Call to Action for Citizen Science: Hear Corrina's passionate defense of the permanence of science funding, why your phone calls to representatives matter, and how everyday people can protect the future of space exploration.

Whether you are looking to reconnect with your own sense of wonder or want a fascinating peek behind the curtain of the world's most advanced radio telescopes, this conversation is the perfect antidote to the noise of everyday life. From political campaigns to the hum of the cosmos, Corrina's journey reminds us just how beautiful and liberating it is to be small.

Gather around the campfire, fellow Star River navigators! In this episode, we sit down with Signe Mason, an Operations Specialist at the world-renowned Very Large Array (VLA) in New Mexico and an astrophysics researcher simulating black holes at Northwestern University for part 2 of her journey down the River.

I continue my conversation with Signe, from the outdoor patio at the Capital Bar and Grill in Socorro, complete with interruptions, sirens, and train horns. Now with more people! The editing on this one got a little wonky because I actually ended part 1 prior to our break, but it was a better place to split the conversatios. So in this "end of part 1 plus part 2,", we look at what made young Signe tick, why astrophysics was the farthest thing from her mind, and how she thinks that overcoming adversiy is what makes us thrive.

Don't forget to listen to part 1 of my conversation with Signe, where the River starts its journey, and the bar was quieter!

What happens when two VLA workers get interviewed without warning in the parking lot of the VLA? Let's find out.

This was in the parking lot of the U.S. National Science Foundation Very Large Array without notice. After the hubbub of the open house had faded for the day, but right as people were starting to arrive for the Star Party and set up their telescopes, one of the workers telling people where to park yelled out, "hey, podcast guy! Can I be on your podcast?" After figuring out that he was only half joking, I surprised him by saying "yes."

It was recorded on my mobile phone. There was a lot of wind. It messed with the microphones on my phone and there are times when the conversation is hard to hear. I suggest headphones.

Warning, this was a pretty raw conversation. I debated editing out some of the edgier parts, but decided that not to. The conversation we had was the one you'll hear, including the swearing.

This is 27 minutes of real, raw conversation recorded in the parking lot of the VLA with Lorenzo Pina and Richard Harding. Two of the blue-collar workers who make it all happen.
