SETI Institute and Breakthrough Listen add agentic AI to Allen Telescope Array search
The SETI Institute and Breakthrough Listen have deployed agentic AI at the Allen Telescope Array in Northern California to accelerate the search for extraterrestrial signals. Researchers can now steer the telescope, calibrate instruments, correct data errors, and run signal-processing models using natural language prompts through a system called Nexus. NVIDIA's Holoscan platform processes up to…
Key points
- Agentic AI steers Allen Telescope Array and processes 2.4 terabits per second in real time
- NVIDIA Holoscan and RTX PRO 6000 Blackwell GPUs enable in-flight data processing on premises
- System achieved first real-time AI detection of Crab Nebula pulsar, evaluating Nemotron next
The pipeline has already achieved the first real-time AI detection of a pulsar in the Crab Nebula. The team is evaluating open models including NVIDIA Nemotron for future deployments where data locality and fast turnaround are critical, such as observatories that may operate on the far side of the moon. Andrew Siemion of the SETI Institute said the new agentic observatories may find signals that have more in common with the AI agents themselves than with their human creators.
