Slowly repeating bursts of intense radio waves from space have puzzled astronomers since they were discovered in 2022.
We know some repeating radio signals come from a kind of neutron star called a radio pulsar, which spins rapidly , beaming out radio waves like a lighthouse. The trouble is, our current theories say a pulsar spinning only once every 18 minutes should not produce radio waves.

This probably indicates that the radio emitter isn't the red dwarf itself, but rather an unseen object in a binary orbit with it.
