Episode 4 - Listening to the Universe: AI, Big Data, and Discovery in Astronomy

In this episode, we talk with Dr. Chiara Stuardi, an astrophysicist and researcher in radio astronomy, about how artificial intelligence is transforming scientific research.Modern astronomy is an extremely data-intensive field, with millions of celestial sources and images that can no longer be analyzed by hand. Using radio astronomy as a case study, we explore how machine learning helps scientists detect faint cosmic structures, work at the limits of noisy data, and turn overwhelming datasets into new discoveries.Along the way, we discuss the role of convolutional neural networks in real research, the challenges of black box models, how scientists validate AI-based results, and whether AI is making science more accessible or raising new barriers. The episode closes with a broader reflection on AI as a tool to accelerate research, not a replacement for human scientists.
