Mysterious radio signal at 45 MHz detected from red dwarf GJ 725A
An international team of astronomers, using the LOFAR radio telescope, has detected coherent radio emission at a frequency of 45 MHz from the red dwarf system GJ 725A, located 11.5 light-years from Earth. This is the lowest-frequency confirmed signal from a star system. Scientists have three main hypotheses for its origin.
