In the toxic waters of Sulphur Cave in Steamboat Springs, Colo. lives blood-red worm blobs that have attracted scientific interest from around the world. We don special breathing gear and go into the cave with David Steinmann, the spelunking scientist who first documented the worms, along with a trio of science students from Georgia Tech, to collect worms and marvel at the unique crystals and cave formations (ever heard of snottites??) that earned Sulphur Cave a designation as a National Natural Landmark in 2021. Then we learn about how extremophiles like these worms are helping scientists search for new antibiotics, medicines, or in the case of the Georgia Tech team, models for worm blob robots that can explore uneven, dangerous terrain, like caves on other planets.

It may seem obvious now that other galaxies lie beyond the Milky Way, but less than 100 years ago, some astronomers held a view of our universe that was a little more ... self-centered. In the 1920s, astronomers were locked in the "Great Debate" — whether Earth was center of the universe and if the universe was just the Milky Way. Today, Scientist in Residence Regina G. Barber talks to Dr. Vicky Scowcroft about the stars that ended astronomy's Great Debate.

NASA's Artemis Moon mission was supposed to launch Monday. But it was delayed due to a problem one of the rocket engines. When it launches, it will be a giant step towards sending humans back to the moon. We're eager to know: What leaps in scientific knowledge will be gained?

It's a question planted in our minds by the scientist Hal Walker, who led an experiment during the first lunar landing half a century ago. The goal: Beam a laser at the moon. This encore episode, Scientist in Residence Regina G. Barber talks to host Aaron Scott about the Lunar Laser Ranging experiment — and how shooting that laser helped us better understand one of Einstein's theories.
