Mysterious Space Signal Pulsed Toward Earth for Seven Hours
Astronomers have detected an unusual and powerful signal from deep space that pulsed toward Earth for an extraordinary seven hours, far longer than typical transient radio signals. The signal's characteristics — its duration, regularity, and intensity — set it apart from known astrophysical phenomena and have left researchers searching for an explanation.
While repeating radio signals from space are not unheard of, most last only milliseconds or seconds. A seven-hour pulsing signal suggests a source with sustained and structured energy output, potentially a new class of astrophysical object or a known object type behaving in an unexpected way. Scientists are conducting follow-up observations to determine the signal's origin and better understand the mechanism producing it.
