Dead Satellite's Signal Confounds Astronomers | JQJO

Australian astronomers detected a powerful radio signal initially believed to be from a distant galaxy. Further investigation revealed the source was Relay 2, a defunct 1964 NASA satellite, approximately 4,500 kilometers away. The signal, likely caused by a massive electrostatic discharge or micrometeorite impact, highlights the growing problem of space debris and its potential interference with astronomical observations. The event underscores the need for improved methods to distinguish between satellite signals and genuine astronomical phenomena, particularly as more satellites populate Earth's orbit.
