2 min readKey summary
Researchers used the VLA and MeerKAT to search the K2-18b system for alien radio technosignatures.
After filtering out Earth interference and instrument noise, the preprint found no convincing artificial narrowband signal.
The null result narrows the SETI search around a high-profile potentially habitable exoplanet.
It also showcases improved radio-search methods for future targets.
