ExEP Tech Colloquium (Virtual)
Exoplanet Exploration Program Technology Colloquium: The Coronagraph Design Survey
Rus Belikov (NASA/ARC), Chris Stark (NASA/GSFC)

In January 2023, the Exoplanet Exploration Program (ExEP) kicked off the Coronagraph Design Survey, chartered to collect and document a broad range of coronagraph designs that may be applicable for NASA’s Habitable Worlds Observatory (HWO). The working group that conducted the Survey, led by Rus Belikov (ARC) and Chris Stark (GSFC), cast a very wide net capturing known and never-heard-of-before novel coronagraph designs. They have completed their 17-month study and will be delivering a final report to the HWO Technical Assessment Group (TAG). Come hear their public briefing of what they learned, and how the results of their survey help point the way to future direct imaging of Earth-like planets.

Building Foundation Models for Science: What happens if we build massive AI models on scientific data?
Shirley Ho (Center for Computational Astrophysics, Flatiron Institute)

In recent years, the fields of natural language processing and computer vision have been revolutionized by the success of large models pretrained with task-agnostic objectives on massive, diverse datasets (e.g. ChatGPT). These so-called "foundation models" have enabled transfer learning on entirely new scales, and have outperformed supervised training models across numerous problems. I will discuss the Polymathic AI initiative, a collaboration between researchers at the Flatiron Institute and scientists around the world. Polymathic AI is designed to spur scientific discovery using similar technology to that powering ChatGPT, we call it "Foundation Models". Using Polymathic AI, scientists will be able to model a broad range of physical systems across different scales.

Featured Video

Celebrating 30 years in orbit, the Hubble Space Telescope has revealed astonishing secrets about our universe. Yet, while its most famous pictures may reveal galaxies and nebulas across the cosmos, it’s also unlocked secrets here in our own solar system.
