NASA Uses AI to Discover Wandering Black Hole Devouring Star
NASA announced that astronomers have discovered a rare "wandering" supermassive black hole tearing apart and consuming a star, aided by an artificial intelligence system.
The event is located about 750 million light-years away in the outskirts of a galaxy, with the black hole having a mass approximately 1 million times that of the Sun. The Zwicky Transient Facility detects about 500,000 flashes each night, and the new AI algorithm automatically identified unusual ultraviolet outbursts consistent with tidal disruption events, which were subsequently confirmed by the Swift Observatory.
AI-assisted screening has significantly improved the efficiency of discovering hidden black holes deviating from the centers of galaxies, with observational resources automatically categorized and tracked across multiple wavelengths, benefiting astronomical teams with AI survey capabilities while traditional manual screening methods are under pressure.

Supermassive black holes typically reside at the centers of galaxies, and wandering (orphan) black holes are difficult to observe directly due to the lack of continuous accretion from a host galaxy core; the instantaneous high-energy radiation from tidal disruption events has become the primary discovery method, with previous similar events mostly concentrated in the nuclear regions of galaxies.
In terms of research pathways, the ZTF's large-scale time-domain survey generates a massive number of candidates, and the AI classification algorithm is specifically trained to identify tidal disruption features deviating from central locations, allowing previously overlooked peripheral events to be prioritized for marking. Swift then follows up with ultraviolet and X-ray observations, forming a closed loop of "AI initial screening - telescope confirmation."
Similar cases can be seen in the search for early supernovae and electromagnetic counterparts of gravitational waves: it is challenging for humans to process hundreds of thousands of transient sources daily, making machine learning a standard pre-filter. The current search for intermediate mass and wandering black holes is in an accelerated phase of "algorithm-driven discovery."
Essentially, this represents a technological replacement: when the volume of survey data far exceeds the limits of manual processing, AI automatic classification directly replaces traditional visual screening, enhancing both discovery efficiency and the capture rate of rare celestial bodies.
