NVIDIA Holoscan Platform Now Powers SETI's Search for Extraterrestrial Signals
NVIDIA says its Holoscan platform and AI agents are being used by Breakthrough Listen and the SETI Institute to search for extraterrestrial signals at the Allen Telescope Array.
Quick answer
How is NVIDIA's technology being used in the search for extraterrestrial intelligence?
NVIDIA says Breakthrough Listen and the SETI Institute have integrated its Holoscan platform and agentic AI into the Allen Telescope Array, letting AI agents steer the telescope, process sensor data in real time and detect signals, including a pulsar in the Crab Nebula, from natural language prompts.
Key takeaways
- NVIDIA says Breakthrough Listen and the SETI Institute have integrated the NVIDIA Holoscan platform into the Allen Telescope Array to support the search for extraterrestrial intelligence.
- According to NVIDIA, AI agents at the observatory can steer the telescope, calibrate the instrument, correct data errors and plot results from a single natural language request.
- NVIDIA says a Holoscan platform library called DAQIRI pulls terabits per second of sensor data directly into GPU memory, while a SETI Institute signal-processing framework called CyberEther performs computations using NVIDIA CUDA-X libraries cuFFT and cuBLAS.
- NVIDIA says the system, orchestrated through a tool called Nexus, can handle 2.4 terabits per second on NVIDIA RTX PRO 6000 Blackwell GPUs with on-premises inference.
- NVIDIA says the pipeline has achieved a first real-time AI detection of a pulsar in the Crab Nebula, and the team is evaluating open models including NVIDIA Nemotron for future offline use cases.
NVIDIA says Breakthrough Listen and the SETI Institute have integrated the NVIDIA Holoscan platform into the search for extraterrestrial intelligence at the Allen Telescope Array in Northern California. According to NVIDIA, agentic AI now allows researchers to steer the instrument, correct incoming data and apply AI models to the data stream through a single natural language request.
How the system works
NVIDIA says a Holoscan platform library called DAQIRI pulls terabits per second of sensor data directly into GPU memory, allowing observations to be processed in flight rather than stored on hard drives first. The company says a SETI Institute signal-processing framework called CyberEther then performs the required computations using NVIDIA CUDA-X libraries, including cuFFT and cuBLAS.
NVIDIA describes a tool called Nexus as a web-based observatory orchestrator that serves as the agent harness for the system. According to the company, Nexus gives agents a single source of truth for instrument state, compute resources and pipelines, and lets researchers monitor packet loss, view live spectrograms and rewrite signal-processing blocks by prompting in natural language.
NVIDIA says the system can handle 2.4 terabits per second of data on NVIDIA RTX PRO 6000 Blackwell GPUs, with inference running on premises next to the telescope. The company says the combined pipeline enables an agent to steer the telescope's antennae, calibrate and focus the instrument for a clean signal, catch and fix data errors, and plot the resulting output.
Results and next steps
According to NVIDIA, the pipeline has already achieved the first real-time AI detection of a pulsar in the Crab Nebula. A pulsar is described in the material as a rapidly spinning stellar remnant that emits pulses like a cosmic lighthouse.
NVIDIA says the team is next evaluating open models, including NVIDIA Nemotron, for cases where data locality and turnaround speed matter most, and for observatories that may eventually operate offline, including a scenario the company describes as the far side of the moon.
