Dr. Steven Kahn, an experimental astrophysicist and former director of the Vera C. Rubin Observatory, delves into the groundbreaking capabilities of the new telescope in Chile. He explains how its massive digital camera will capture a time-lapse 'movie' of the night sky, enabling the detection of countless galaxies and transient events. Kahn also discusses the challenges of constructing such an advanced facility, its mission to explore dark matter and energy, and how citizen scientists can get involved in unraveling the mysteries of our universe.

Episode notes
Precision Through Massive Samples
- Rubin is designed as a precision "statistics machine" to push many measurements below 1% uncertainty.
- Understanding instrument and atmosphere in detail is crucial to exploit huge sample sizes.
Democratizing Astronomy
- Rubin aims to democratize discovery: anyone can access images and study assigned galaxies.
- The project intentionally supports education, community colleges, and citizen engagement.
A Vast, Public Astronomy Archive
- Rubin's final data archive will total ~100 petabytes and exceed all prior astronomical images combined.
- The dataset will be public and accessible for broad scientific and educational use.
