Jun 10, 2025
Dr. Cara Battersby, an associate professor at the University of Connecticut and head of the Milky Way Laboratory, reveals fascinating insights about the previously obscured center of our galaxy. She discusses how modern telescopes have unveiled the complex dynamics of star formation near the supermassive black hole, Sagittarius A*. Cara also highlights the challenges of creating a 3D map of the central molecular zone, the role of the ALMA telescope, and ongoing research that could reshape our understanding of cosmic phenomena.

Episode notes
Zone of Avoidance Unveiled
- The central part of the Milky Way was long called the Zone of Avoidance due to dust blocking visible light.
- Modern telescopes now see through this to reveal the molecular gas and star formation near the supermassive black hole.
Central Molecular Zone as Mini Galaxy
- The central molecular zone is physically separated and vastly different from the Milky Way's outskirts.
- It acts like a mini galaxy with intense gas flows, turbulence, and star formation near the supermassive black hole.
Galactic Center's Extreme Environment
- The galactic center is as hostile to life as expected due to radiation and exotic events.
- Nevertheless, its stellar density would make the night sky there stunningly bright and beautiful to visit.
