Today’s episode—released to coincide with the announcement of an astronomical discovery—brings us inside the exciting world of scientific inquiry. In 2020, a group of scientists discovered a star-producing cosmic ripple in the local arm of the Milky Way that changed scientists’ understanding of the galaxy that our solar system calls home. They named it the Radcliffe Wave after the generative environment that inspired the finding. And the discoveries keep coming: new research published in Nature confirms that the Radcliffe Wave is indeed in motion, as its name suggests. Today, we talk to four of the scientists who collaborated on this groundbreaking research about what it all means.

Episode Transcript
Guests
João Alves is a professor of stellar astrophysics at the University of Vienna. During his Radcliffe fellowship year in 2018–2019, he combined both space and ground-based observational data to build the first map of the space motion of gas and to investigate how giant gas clouds, the nurseries of stars, came to be.
Alyssa A. Goodman is the Robert Wheeler Willson Professor of Applied Astronomy at Harvard University, a former codirector for science at Harvard Radcliffe Institute, a research associate of the Smithsonian Institution, and the founding director of the Harvard Initiative in Innovative Computing. She was a Radcliffe fellow in 2016–2017, and her work spans astrophysics, science education, data science, data visualization, and prediction.
Ralf Konietzka is a PhD student in astronomy and astrophysics at Harvard University. His research focuses on the formation and evolution of the Milky Way, and he uses a combination of analytic theory, observations, data visualization, and numerical simulations to investigate the structure and dynamics of the local interstellar medium and examine how stars originate.
Catherine Zucker, who earned her PhD from Harvard University in 2020, is an astrophysicist at the Center for Astrophysics | Harvard & Smithsonian whose research focuses on developing novel techniques to tease out the 3D structure and dynamics of our home galaxy, the Milky Way. Much of her work involves the use of “big data” and high-performance computing.
