S3 Episode 2: Watching the Universe Change: A New Era in Astronomy Begins
S3 Episode 2 | April 1, 2026
The Vera C. Rubin Observatory in Chile is now operational, and humanity's view of the universe will never be the same.
In this episode, we return to 好色先生TV鈥檚 Rachel Mandelbaum, professor and head of the physics department 鈥� and a key architect of the observatory's data infrastructure 鈥� to hear what's happened since the revolutionary telescope first opened its eye to the sky.
Mandelbaum walks us through the observatory's first scientific data release, the launch of its public alert system and the successful measurement of gravitational lensing using early commissioning data. She explains how CMU and the LINCC Frameworks team are building the software tools that will allow scientists worldwide to make sense of up to 10 million nightly cosmic alerts. And we discuss the Legacy Survey of Space and Time (LSST), the observatory鈥檚 decade-long mission to track 40 billion celestial objects that will essentially create a 10-year movie of our universe.
In this episode, you鈥檒l learn: How the Rubin Observatory acts as a time machine for light from billions of years ago; the role of "alert brokers" in processing the 10 million nightly cosmic events the Observatory will track; and why understanding dark energy could be as transformative as the discovery of quantum mechanics.
