AI agents now steer the hunt for alien signals at the Allen Telescope Array
The search for life beyond Earth has a new helper: artificial intelligence. Breakthrough Listen and the SETI Institute have brought AI agents into the daily search for extraterrestrial intelligence at the Allen Telescope Array in Northern California, announced on Friday, 30 October 2026.
The agents can steer the telescope, correct incoming data, and run AI models on the live stream — all from a single request in plain language. The system is built on NVIDIA’s Holoscan platform. A tool called DAQIRI pulls huge streams of sensor data straight into computer memory, so observations are processed as they happen. The SETI Institute’s CyberEther software does the maths, and a web-based system called Nexus lets researchers watch the data and change settings with plain typed instructions.
The setup can handle 2.4 terabits of data every second on NVIDIA RTX PRO 6000 Blackwell graphics processors, with the computing done on site. NVIDIA says the agents can compress work that would take humans weeks or years into hours.
The system has already proved itself: it made the first real-time AI detection of a pulsar — a rapidly spinning stellar remnant that pulses like a lighthouse — in the Crab Nebula. That is a known natural object, not a signal from aliens. No signal from another civilisation has been found.
Andrew Siemion, the SETI Institute’s lead scientist for Breakthrough Listen, called the step “a breakthrough in translation” — human-built AI listening for AI built by someone else.
Why it matters
Radio telescopes produce far more data than people can watch live. A strange signal lasting a few seconds can be missed, or found only months later. AI agents that steer the telescope and check data in real time give scientists a better chance of spotting something unusual while it happens, and free researchers to focus on the most interesting signals.
What happens next
The team is now testing open AI models, including NVIDIA’s Nemotron, for use where data must stay local and replies must be fast — including observatories that could one day work offline on the far side of the Moon. The search goes on at the Allen Telescope Array, with the agents watching the sky around the clock.
